Their primary purpose is to preserve and promote free competition. It is NCMA’s policy to strictly comply in all respects with the antitrust laws. Association meetings or workshops by their very nature bring competitors together. Accordingly, it is absolutely necessary to avoid discussions of legally sensitive topics and especially important to avoid recommendations with respect to these sensitive subjects. Agreements to fix prices, allocate markets or customers, engage in product boycotts and to refuse to deal with third parties are automatically or per se illegal under the antitrust laws. It doesn't matter what the reason for the agreement. Accordingly, at any association meeting discussions of prices, including elements of prices such as allowances and credit terms, quality ratings of suppliers, and discussions which may cause a competitor to cease purchasing from a particular supplier, or selling to a particular customer, must be avoided. Also, there should be no discussion that might be interpreted as a dividing up of territories or customers. An antitrust violation does not require proof of a formal agreement. A discussion of a sensitive topic, such as prices, followed by parallel action by those involved in or present at the discussion is enough to show a price fixing conspiracy. As a result, those attending an associationsponsored meeting must remember the importance of avoiding not only unlawful activities, but even the appearance of unlawful activity. As a practical matter, violations of these rules can have serious consequences for a company and its employees. The Sherman Antitrust Act is both a civil and criminal statute. Violations are felonies punishable by penalties of up to $10 million for corporations and by imprisonment of up to three years or penalties of up to $100,000, or both, for individuals. The Justice Department, state attorney general, and any person or company injured by a violation of the antitrust laws may bring civil actions for three times the amount of the damages, plus attorneys' fees and injunctive relief. Antitrust investigations and litigation are lengthy, complex, disruptive and expensive. Therefore, all companies and their employees must not only comply with the antitrust laws in fact, but must conduct themselves in a manner that avoids even the slightest suspicion that the law is being violated. Associations, because they bring competitors together, are natural targets, along with members alleged to have participated with or through the association. The following is a list of topics that must never be the subject of any type of agreement among competitors, whether explicit or implicit, formal or informal. Such topics should NEVER be discussed at association meetings. This list is not exhaustive of prohibited topics or subjects. Please consult legal counsel in the event of any confusion or question over whether a topic is permissible or appropriate for discussion among association members: a. b. c. d. e. f. g. h. i. j. k. l. m. n. o. Prices to be charged to clients, customers or by suppliers; Specific methods by which prices are determined, with directions as to "how to do it" or even less; Division or allocation of markets or customers; Coordination of bids or requests for bids; Terms and conditions of sales, including credit or discount terms; Terms for distribution of products; Targets for production of products or the level of production; Specific profit levels; Exchange of price information as to specific customers; A boycott of or a refusal to deal with a customer or supplier; Compilation of “approved” lists of customers or suppliers. "Profit" levels...i.e., "here's what our members need to do to make money." Whether a company's pricing practices are “unethical,” “improper,” etc. Coordination of "bids" or "requests for bids" or requests for proposals ("RFPs"). Standards or codes to eliminate competition. When in doubt about discussing any topic, consult with your own legal counsel, or with association staff or its legal counsel, to be sure you are on safe antitrust ground. When unsure, play it safe and avoid the topic. Conflict of Interest Considerations: placing (or the appearance of placing) one's own self-interest or any third-party interest above that of the Association; while the receipt of incidental personal or third-party benefit may necessarily flow from certain Association activities, such benefit must be merely incidental to the primary benefit to the Association and its purposes; abusing their Board membership by improperly using their Board membership or the Association's staff, services, equipment, resources, or property for their personal or third-party gain or pleasure, or representing to third parties that their authority as a Board member extends any further than that which it actually extends; engaging in any outside business, professional or other activities that would directly or indirectly materially adversely affect the Association; engaging in or facilitate any discriminatory or harassing behavior directed toward Association staff, members, officers, directors, meeting attendees, exhibitors, advertisers, sponsors, suppliers, contractors, or others in the context of activities relating to the Association; soliciting or accepting gifts, gratuities, free trips, honoraria, personal property, or any other item of value from any person or entity as a direct or indirect inducement to provide special treatment to such donor with respect to matters pertaining to the Association without fully disclosing such items to the Board of Directors; and providing goods or services to the Association as a paid vendor to the Association only after full disclosure to, and advance approval by, the Board, and pursuant to any related procedures adopted by the Board.

Call to Order and Introductions The meeting was called to order at 10:45 AM. It was noted that a quorum was present. 2. Review of the NCMA Antitrust Policy Statement The chairman directed the committee’s attention to NCMA’s antitrust statement for review. The chairman asked all to comply with the intent of this policy. 3. Overview of Meeting Structure Dave Mariner explained the structure of the meetings for the day and encouraged everyone to flexible in discussion. 4. Review of the Agenda The agenda was approved as presented. Manufactured Stone Market Segment Committee – July 29, 2014 J:\Committee Activities\Midyear Meeting\2014\Cmte Minutes\Approved\Minutes - Manf Stone Market Segment - MY14.docx Date revised: 8/11/14\RHH/brkt Page 2 of 8 5. Review of the Minutes The minutes of the previous meeting were reviewed and approved as presented. Chris Hines made a motion to accept the minutes and Danielle Bach second. 6. Review of Manufactured Stone Strategic Plan and Objective Dave opened this part of the meeting with expressing the goal to have an open discussion and critique the strategic plan and encourage feedback to start deciding the direction NCMA should take in relation to MVMA members and their goals within NCMA. He asked for everyone to think about what pieces of the day’s discussion add the most value to the MVMA members. He briefly mentioned Coronodo’s resignation due to the company’s feeling that NCMA was going in to many directions and the feeling that the focus should be strictly on technical, most specifically the ASTM standards and code process. 7. Subcommittee Meetings and Reports 7.1. Manufactured Stone Communications Subcommittee (Richard Kelly) – 11:00 am Richard Kelly called the meeting to order 10:55 am 7.1.1. Approval of February 7, 2014 Manufactured Stone Communications Subcommittee Meeting Minutes Bobby Staten made a motion to approve the minutes, Chris Hines seconded. They were approved unanimously. 7.1.2. Cost versus Value Study Clare Ramminger gave a recap of the MVMA participation in Hanley-Wood’s Remodeling magazine’s Cost vs. Value Study. There was discussion regarding how Hanley Wood developed their costs. The information will be available in January 2015. NCMA staff was asked to send out a press release once the study is available disseminate the information to link to members when it becomes available. NCMA will link the survey from MSV section of the website directly to the survey. 7.1.3. Shipment Report Clare Ramminger reported that there are eight companies currently participating in the Shipper’s Report. Only the members who participate in the program get the report. There was discussion about improving the details of the information for the report. All were encouraged to participate. Dave Mariner asked for a phone call to follow-up on improving the information breakdown that could increase participation. 7.1.4. Tradeshow Participation Strategy There was discussion regarding MVMA’s participation in the WOC/WOM last year and it was decided that this was not the best venue for the MVMA to focus. There were similar feelings regarding the International Builder’s Show. Staff shared that NCMA was participating in Hardscape North America and that MSV products will be included. It was suggested that NCMA should list all MVMA members in NCMA booth. 7.1.5. Promotion and Outreach Activities 7.1.5.1. Distribution Plan for 4th Edition of Installation Guide The distribution of the new Installation Guide includes hosting on MSV section of the website. Members were encouraged to link to the site directly. We do not want people to download the PDF and then host it on their website. Our information is copyrighted. Staff showed members also how to purchase from the Bookstore. Manufactured Stone Market Segment Committee – July 29, 2014 J:\Committee Activities\Midyear Meeting\2014\Cmte Minutes\Approved\Minutes - Manf Stone Market Segment - MY14.docx Date revised: 8/11/14\RHH/brkt Page 3 of 8 Advisory Item A motion was made by Chris Hines and seconded by Dan Krouse to recommend that the logos and website addresses of MVMA members of NCMA be added to the back cover of the Installation Guidelines. The subcommittee discussed ways to add value to MVMA membership, and how to promote the members of the association. One cost-neutral way of achieving this is to add the logos off all MVMA members of NCMA be added to the back cover of the Installation Guide. The back cover is nearly blank at this time, and it will be fairly easy to add those logos. Additionally, since NCMA uses electronic distribution of materials and ‘print-on-demand’, maintenance of these logos (when someone joins or leaves the association) can be performed expeditiously. The motion was approved by a vote of 7 in support, 0 opposed and 0 abstaining. The motion was accepted by the Manufactured Stone Committee. None. Motion: Discussion: Vote: Minority Position: Strategic Plan Relevance: Note—Item was accepted as advisory by the NCMA Board of Directors on August 1, 2014. 7.1.5.2. ASTM Standards – ASTM C1670 (Product Spec) and ASTM C1780 (Installation) Items were mentioned but deferred discussion to the MSV Technical Subcommittee. 7.1.5.3. TEK Section 20 – Manufactured Stone Veneer Staff showed the current plans to produce a MSV TEK Section. 7.1.5.4. Website and Solutions Center Staff showed the new website and the MSV section. Materials are easily accessible from this section of the website. Need to be careful about pictures of projects that are non-compliant with installation guidelines. The Solutions Center was also shown and how to become a sponsor was discussed. 7.1.5.4.1. Electronic Posting and Distribution Practices Discussed in previous parts of the meeting. Encourage members to link directly to NCMA site. 7.1.5.5. Laboratory Testing Promotional Offer Promotion is currently being offered and members are encouraged to send product to the lab for testing. NCMA needs data. 7.1.5.6. Concrete Masonry Designs – Masonry The Masonry issue of the magazine will be distributed shortly and includes some MSV projects as well as the FAQ about the ASTM standards. 7.1.6. Student Outreach 7.1.6.1. Student Design and Unit Design Competitions NCMA staff explained the current NCMA Foundation program. The committee discussed and decided that this is not something that they would consider right now. 7.1.6.2. Incorporation into University Curriculum NCMA staff explained the current NCMA Foundation supported programs. While the committee thought this was interesting, there was nothing to purse at this time. 7.1.7. Design Awards NCMA staff indicated that Design Awards program will launch in January and MSV is included in the program. Manufactured Stone Market Segment Committee – July 29, 2014 J:\Committee Activities\Midyear Meeting\2014\Cmte Minutes\Approved\Minutes - Manf Stone Market Segment - MY14.docx Date revised: 8/11/14\RHH/brkt Page 4 of 8 7.1.8. Other Business Possible Trade Show Participation – North American Masonry Conference, AIA Trade Show 7.1.9. Adjournment Richard Kelly thanked everyone and adjourned the meeting at 12:30 pm. 7.2. Manufactured Stone Technical Subcommittee (Chris Hines) 7.2.1. Approval of February 7, 2014 Manufactured Stone Technical Subcommittee Meeting Minutes Dan Krouse made a motion to approve the minutes and Tony Fuller seconded. All approved. 7.2.2. Review of Identified Activities and Work Products Staff reviewed the various initiatives and projects the MSV Technical Subcommittee is overseeing. They include: 4th Edition Installation Guide – The installation guide has been completed and posted to the web. Addition potential revisions will be discussed under Agenda Item 7.2.3. Certification – To be discussed under Agenda Item 10. Research – Earlier this year the Subcommittee recommended investigating the performance of installing MSV over continuous insulation. ASTM Referencing – Staff has been directed to initiate the process of incorporating references to ASTM C1670 and ASTM C1780 into building codes. This process has been initiated. Product Testing – NCMA’s Lab is offering a free set of tests to each member producer. Literature Development o TEK 20-1; Installation Practices: Drafted, pending review. o FAQ 4-14; ASTM Standards: Completed. o Installation Guide: Completed. o TEK 20-X; Control Joints: Under development. o TEK 20-X; Water Penetration Resistance: Under development. o TEK 20-X; Seismic Design: Under development. o TEK 20-X; Efflorescence Control: Under development. Activities and resources associated with each of these projects will be prioritized later in the meeting. 7.2.3. Lath Installation Orientation Recommendations Upon the release of the 4th Edition of the Installation Guide, several noted a typo in the section discussing the installation orientation of lath. In discussing potential fixes to this language, it became clear that additional clarifying discussion could be incorporated into this section of the Installation Guide to offer better guidance in the field during construction., specifically the confusion resulting from the term ‘cups’. Chris Little summarized the differences between industry best practices and minimum installation requirements dictated by existing codes and standards. ASTM C1063 requires that lath be installed horizontally along the length of the wall, and in the case of self-furring lath, requires the dimples/furring to be against the wall surface, but do not dictate the orientation of the lath cups. It was also noted that the adage ‘like a good whiskey; smooth going down and rough coming up’ applies to lath installation orientation. Staff was directed to draft some new language for possible inclusion in the Installation Guide that clarifies the practices associated with lath installation, differentiates minimum code requirements from industry practices, and removes the term ‘cups’ from the discussion. 7.2.4. Needs Assessment – ASTM C1670, Standard Specification for Adhered Manufactured Stone Masonry Veneer Units Staff reported that they have initiated some in-house trial testing on manufactured stone units to begin to establish a database of information that could be used to support improvements to ASTM C1670. As part of this testing it was observed that some inconsistencies were noted, and while the source of these Manufactured Stone Market Segment Committee – July 29, 2014 J:\Committee Activities\Midyear Meeting\2014\Cmte Minutes\Approved\Minutes - Manf Stone Market Segment - MY14.docx Date revised: 8/11/14\RHH/brkt Page 5 of 8 inconsistencies is not know at this time, the working theory that the rate of water absorption of stone units may be influencing the measured results being evaluated; particularly freeze/thaw and shrinkage testing. To date the Lab has initiated absorption testing of multiple sets of units from several different production sources to begin to quantify the rate of water absorption. General observations thus far include: Deep vs. Shallow Immersion Does Not Seem to be Critical Average Weight Increase at 24 hours = 13% Average Weight Increase at 48 hours = 14% Average Weight Increase at 264 hours = 15% Average 24/48 Hour Saturation = 95% Average 24/264 Hour Saturation = 87% The Subcommittee agreed that understanding and resolving these testing differences should take precedence over the currently planned research project investigating installation over insulation. Action Item A motion was made by Craig Walloch and seconded by Chris Hines to recommend that the $25,000 included in the 2014 budget, originally designated for researching the installation of manufactured stone over continuous insulation, be instead reallocated to research and benchmark manufactured stone unit properties. Background Discussion: Preliminary testing of manufactured stone units using the recently approved ASTM C1670 criteria has shown some unanticipated inconsistencies in the measured results. The Committee agrees that investigating and resolving these issues should take precedence over the currently planned project to assess the impacts of installing manufactured stone over continuous rigid insulation. Vote: The motion was approved by a vote of 10 in support, 0 opposed, and 0 abstaining. Minority Position: None. Strategic Plan Relevance: Quality of Units Note—Action item was approved by the NCMA Board of Directors on August 1, 2014. Motion: Given this reprioritization, the Subcommittee also agreed to disband its current task groups. Once the unit testing evaluation is complete, additional task groups can be established as needed to tackle specific tasks. Advisory Item A motion was made by Bobby Staten and seconded by Danielle Bach to recommend that the three task groups (Research, Installation, and Unit Spec Task Groups) reporting to the MSV Technical Subcommittee be disbanded. Background Discussion: With the finalization of the 4th Edition of the Installation Guide, the tasks assigned to the Installation Task Group have been completed. Further, with the recommendation to reprioritize available research funds in 2014, the Research Task Group is no longer needed for the immediate future. Finally, given the nearly identical membership between the MSV Technical Subcommittee and the Unit Spec Task Group, activities can be streamlined through consolidation. Vote: The motion was approved by a vote of 11 in support, 0 opposed, and 0 abstaining. Minority Position: None. Strategic Plan Relevance: NA Note—Item was accepted as advisory by the NCMA Board of Directors on August 1, 2014. Motion: 7.2.5. Other Business Chris Hines surveyed the Subcommittee for additional critical topics that should be on the short list for future consideration. These include: Understanding and evaluating the bond characteristics of manufactured stone. Educating and enforcing proper moisture management techniques and industry installation practices. Proper techniques for installation manufactured stone over continuous insulation. Manufactured Stone Market Segment Committee – July 29, 2014 J:\Committee Activities\Midyear Meeting\2014\Cmte Minutes\Approved\Minutes - Manf Stone Market Segment - MY14.docx Date revised: 8/11/14\RHH/brkt Page 6 of 8 8. Reconvene Manufactured Stone Committee Meeting Dave Mariner Reconvened the MSV meeting. The committee went through the Draft MSV strategic plan and decided what was of high priority for the MVMA members. 9. Education Strategies and Opportunities Not discussed 10. Overview of Related Certification Programs Not discussed specifically 10.1. Installer Certification Discussed that this is not main priority, but should continue encouraging people follow the Installation Guide. However, if Staff has the opportunity to educate at speaking program engagements where the MVMA does not incur costs, they should pursue those. 10.2. Production Certification Discussed the pros and cons of the having a certification, but was decided that this was not a priority right now. 11. Committee Structure and Membership 11.1. Meeting Venue and Format Briefly discussed that the traditional NCMA Meeting format may not be what MVMA members need, but that the one-day track was much better received. 11.2. Leadership Roles Dave Mariner told the committee that he will be moving to Australia at the end of the year and asked if there were any volunteers for his position. 12. Dues and Bylaws Issues Dave Mariner suggested that NCMA look at what MVMA members are currently paying in dues and reevaluate the fees. He did mention that he feels that NCMA is much better than their previous management company and there is good value in that. 13. Membership 13.1. Review of Membership Status Members were encouraged to look at the current list of members and try to help identify who are potential MSV members. 13.2. Membership Promotion Nothing discussed at this time. 14. Review and Prioritization of 2015 Budget and Work Plan Staff to revise Strategic plan and move forward from there. Most notably, it was decided that external outreach and communications/promotional activities were not of the highest priority for this group. If NCMA is working on a program, MVMA members should be included as long as there is no extra cost to the members. 15. Review and Approval of Manufactured Stone Market Segment Strategic Plan and Objectives Revised plan will be distributed for approval by the committee. 16. Other Business Nothing discussed at this time.

This plan is organized into several sections, generally defined as follows: CORE OBJECTIVES – these are the primary focus of industry efforts for the near future. BEDROCK PROGRAMS – these are programs that are intended to protect the interests of the industry, as well as provide a basic level of service from the Association. GUIDING PRINCIPLES – These are principles to be considered when creating projects and objectives. POSSIBLE FUTURE PROGRAMS – these are possible programs and initiatives that have been discussed previously but are not included in the current work plan. They are maintained here as a ‘parking lot’ for future consideration. CORE OBJECTIVES – The following is a list of prioritized objectives on which NCMA should focus its efforts through 2015 to achieve the greatest return for the members of the association through expansion of the marketplace for manufactured stone veneer products. 1. Quality of Units – Improve the overall industry quality and the perceived quality of manufactured stone veneer and provide mechanisms to distinguish those with better quality. Strategies to accomplish this objective: Standards for Manufactured Units – improve ASTM unit standards to include appropriate performance requirements and test methods to consistently measure performance. Compliance with Unit Standards – encourage compliance testing of products by manufacturers, educate manufacturers on unit criteria, test methods, and preparation of specimens for testing, increase awareness level of specifiers of existence of standards, and encourage specifications to require compliance. Quality Assurance – Develop industry recommendations for quality control and quality assurance for manufactured stone veneer units. Plant Accreditation/Product Certification – develop and promote accreditation programs intended to ensure the production and delivery of quality units in conformance with established product specifications. 2. Quality of Walls – Improve the installation of manufactured stone veneers and improve the perception of the quality of the finished wall system. Strategies to accomplish this objective: Industry Recommendations for Installation – Develop, publish and disseminate best practices and details for installation to result in quality walls. Research Wall Systems – Conduct and support research to support development of industry recommendations for design and installation. Codes and Standards – Support appropriate provisions in building codes and standards to ensure cost-effective, quality walls. II. System Education – Improve the level of understanding by designers, owners, installers, inspectors, and industry representatives on appropriate design, installation, and selection of materials to achieve quality adhered veneer masonry systems. Strategies to accomplish this objective: Educate Installers – Develop and support programs to improve the level of knowledge of installers. Educate Designers – Develop and support programs to improve the level of knowledge of designers Educate Inspectors - Develop and support programs to improve the level of knowledge of inspectors 3. Other Objectives – While not identified to the same level of program priority as those above, the following issues/topics were also identified as important to market and member success. Improve Industry Participation – increase the number of companies participating in industry efforts and improve the nature of their participation. Industry Shipments Reports – conduct quarterly shipments reports for those companies participating. Promote Current Industry Projects and Resources – promotion of resources such as the MVMA Installation Guide, and positive results of the Cost vs. Value study. DRAFT BEDROCK PROGRAM and SERVICES - The following list of programs and services are those that are considered essential to the effective operations of the association. In terms of priority, resources must be maintained for these programs and services before additional resources are allocated to address other specific objectives as outlined above. 1. Advance and protect manufactured stone position within the following codes, standards, and regulations: a. International Codes (IBC, IRC, etc.) - protect b. ASTM Committee C15 (manufactured masonry units) – protect/advance c. Green standards and rating systems (USGBC, sustainable sites initiative, etc.) – advance/protect 2. Maintain on-staff technical competency and: a. provide technical support to members, contractors, designers, and other related constituent groups, b. maintain relevant existing technical resources, and c. conduct technical seminars. 3. Keep the membership informed of important issues and events related to manufactured stone veneer products market. Communicate and collaborate with other national, regional, and state associations that have similar industry interests to leverage NCMA’s abilities to accomplish objectives. 4. Educate members and users about manufactured stone veneer products. GUIDING PRINCIPLES – the following principles should be taken into account in developing projects and allocating resources to best achieve desired outcomes. 1.

The National Concrete Masonry Association (NCMA) is the national trade organization representing manufacturers of manufactured stone veneer products and as such AC51 is certainly important to us and our membership. NCMA represents producers of many manufactured concrete products, including manufactured stone veneer (also known as ‘precast stone veneer’ and ‘adhered manufactured stone masonry veneer’) that are a part of the Masonry Veneer Manufacturer’s Association (MVMA), which is a part of NCMA. The discussion items included in the open later dated December 1, 2014 to all parties interested in precast stone veneer have been reviewed by the technical staff at NCMA with contributions from constituency of our manufactured stone veneer members. The review of the AC-51 document has given rise to a number of valid questions, particularly related to the sampling procedures of testing and verification of pertinent physical attributes such as average thickness and saturated unit weight. Further, the comparison of the AC-51 document and the related ASTM C1670, Standard Specification for Adhered Manufactured Stone Masonry Veneer (AMSMV) Units, has clearly defined the differences in requirements for testing and related properties. It should first be brought to the attention of those involved in the review of the AC-51 document, that there is a more current version of the ASTM standard than the 2013 version, referenced in the letter from ICC-ES. The most recent version at the time of developing these comments is ASTM C1670/C1670M-14. This updated version has incorporated changes that bring some clarity to sampling, testing, and physical requirements which may resolve some of the questions posed in the open letter. Specifically, the open letter has several questions relating to number of units to evaluate for dimensions and installed weight. While this issue continues to be debated within ASTM Committees, the most recent version of ASTM C1670/C1670M does address minimum numbers of units to sample for various tests. NCMA does not share the interpretation offered by ICC-ES that ASTM C1670/C1670M requires evaluation of every unit for weight. The standard, requires testing on a representative sample, and that all units are intended to be manufactured to comply with the code requirements for dimensions and weight, but evaluation of every unit shape would be onerous and unnecessary. ASTM C1670/C1670M-14 is the result of over eight years of standard development at ASTM, with significant input from manufactured stone veneer producers, users, and many other interested parties. The requirements within this standard are those necessary to assure quality of manufactured stone units, and units complying with these requirements meet all necessary code provisions for these units. Rather than create a second set of similar requirements, AC-51 should simply reference ASTM C1670/C1670M-14 for physical requirements for manufactured stone veneer units. This is consistent with how other materials within AC 51 are handled (for example, ASTM C926 is referenced for cement plaster). This change would also simplify the marketplace for both producers of these products as well as users, since only a single set of physical requirements would exist for these materials. In addition, an ASTM standard for installation of manufactured stone veneer systems has been developed. ASTM C1780-14, Standard Practice for Adhered Manufactured Stone Masonry Veneer, provides minimum standards for installation of manufactured stone veneer systems over a wide range of structural back-up systems. It is also the opinion of this organization and its members that AC 51 reference ASTM C1780 for installation practices. As part of these comments, attached is a marked-up version of AC-51 with proposed revisions from NCMA to establish a compliance path for units to meet ASTM C1670/C1670M, and with installation methods to comply with ASTM C1780. It is acknowledged that there may be other systems besides those covered under these standards that may utilize AC-51, so a compliance path using the current AC-51 revisions is maintained (with some minor modifications to simplify testing requirements in some places). Also contained in this markup are some other editorial and minor revisions with the intent to improve the overall content of AC-51. The longstanding goal in the development of these standards has been formal reference in TMS 402/602, Building Code Requirements and Specifications of Masonry Structures. Upon formal adoption, which in turn would make these standards part of the International Building and Residential Codes by reference, the need to coordinate AC-51 with these standards becomes more important. With that, AC51 should reference developed consensus standards for both unit requirements (ASTM C1670/C1670M14) as well as installation practices (ASTM C1780) for manufactured stone veneer systems.

Dowds Manager, Research and Development Laboratory www.icc-es.org | (800) 423-6587 | (562) 699-0543 A Subsidiary of the International Code Council ® ACCEPTANCE CRITERIA FOR PRECAST STONE VENEER AC51 Approved February 2008 Effective March 1, 2008 (Editorially revised April 2012) Previously revised September 2010 PREFACE Evaluation reports issued by ICC Evaluation Service, LLC (ICC-ES), are based upon performance features of the International family of codes. (Some reports may also reference older code families such as the BOCA National Codes, the Standard Codes, and the Uniform Codes.) Section 104.11 of the International Building Code® reads as follows: The provisions of this code are not intended to prevent the installation of any materials or to prohibit any design or method of construction not specifically prescribed by this code, provided that any such alternative has been approved. An alternative material, design or method of construction shall be approved where the building official finds that the proposed design is satisfactory and complies with the intent of the provisions of this code, and that the material, method or work offered is, for the purpose intended, at least the equivalent of that prescribed in this code in quality, strength, effectiveness, fire resistance, durability and safety. This acceptance criteria has been issued to provide interested parties with guidelines for demonstrating compliance with performance features of the codes referenced in the criteria. The criteria was developed through a transparent process involving public hearings of the ICC-ES Evaluation Committee, and/or on-line postings where public comment was solicited. New acceptance criteria will only have an “approved” date, which is the date the document was approved by the Evaluation Committee. When existing acceptance criteria are revised, the Evaluation Committee will decide whether the revised document should carry only an “approved” date, or an “approved” date combined with a “compliance” date. The compliance date is the date by which relevant evaluation reports must comply with the requirements of the criteria. See the ICC-ES web site for more information on compliance dates. If this criteria is a revised edition, a solid vertical line (│) in the margin within the criteria indicates a change from the previous edition. A deletion indicator (→) is provided in the margin where any significant wording has been deleted. ICC-ES may consider alternate criteria for report approval, provided the report applicant submits data demonstrating that the alternate criteria are at least equivalent to the criteria set forth in this document, and otherwise demonstrate compliance with the performance features of the codes. ICC-ES retains the right to refuse to issue or renew any evaluation report, if the applicable product, material, or method of construction is such that either unusual care with its installation or use must be exercised for satisfactory performance, or if malfunctioning is apt to cause injury or unreasonable damage. NOTE: The Preface for ICC-ES acceptance criteria was revised in July 2011 to reflect changes in policy. Acceptance criteria are developed for use solely by ICC-ES for purpose of issuing ICC-ES evaluation reports. Copyright © 2012 ACCEPTANCE CRITERIA FOR PRECAST STONE VENEER (AC 51) 1.0 INTRODUCTION 1.1 Purpose: The purpose of this criteria is to establish the minimum requirements for recognition of adhered precast stone veneer in ICC Evaluation Service, LLC (ICC-ES), evaluation reports under the 2015, 2012, 2009 and 2006 International Building Code® (IBC), and the 2015, 2012, 2009 and 2006 International Residential Code®(IRC). This criteria is needed to clarify the requirements for composition, strength, durability and installation of precast stone veneer, which are not addressed in the code. 1.2 Scope: This criteria applies to precast stone veneer adhered with mortar to the exterior face of exterior walls and, at the report applicant’s option, to interior wall surfaces. The veneer system is considered a variation of exterior plaster regulated by IBC Section 2512, and 2015 IRC Section R703.7 (Section R703.6 of the 2012, 2009 and 2006 IRC), and a variation of adhered masonry veneer regulated by IBC Section 1405.10 (Section 1405.9 of the 2006 IBC). The veneer may be adhered to backings consisting of concrete, masonry or cement plaster mortar applied over metal or wire fabric lath. 1.3 Codes and Reference Standards: Where standards are referenced in this criteria, the standards shall be applied consistent with the requirements of the applicable code.

Approval of Agenda The agenda was approved as presented. Review of Ballot Items Subcmte Ballot C 15 (14-02) Item 16 ASTM C 1670, Spec for Adhered Manufactured Stone Masonry Veneer Consideration of Subcmte Negative by Donald Harvey Consideration of Subcmte Negative by Herb Nordmeyer Consideration of Subcmte Negative by John Swink Consideration of Subcmte Negative by Luis Carr Consideration of Subcmte Negative by Michael D. Lewis Consideration of Subcmte Negative by William McGinley Consideration of Subcmte Comment by Ian Chin o After initial review of all comments and negatives regarding the proposed change to remove the shrinkage requirements for adhered manufactured stone masonry veneer units a thorough discussion ensued. Mr. McGinley voiced concerns over bond delamination as a result of an excessive rate of linear drying shrinkage of units in a wall assembly. All agreed that due to the complexities of this composite wall system more investigation is necessary to determine an adequate acceptance criterion for linear drying shrinkage of MSV units, if any. Ron Kozikowski also voiced concerns over the validity of testing per ASTM C426, and proposed investigating the testing of shrinkage without inducing the initial swell of units per C426. It was decided to reviewing shrinkage requirements after the conclusion of ongoing NCMA research regarding MSV units. Subcmte Ballot C15.03 (14-02) Item 17 ASTM C 1670, Spec for Adhered Manf. Stone Masonry Veneer Consideration of Subcmte Negative Vote by Jeffery F. Speck – After discussion by the task group, Mr. Speck’s negative was found to be persuasive under the rationale that ASTM C330, although technically structured for structural concrete, is applicable for MSV units, a wet cast product. The more stringent materials requirements of C330 align within the harsher exposure commonplace with veneer units. It was decided to re-ballot to remove references to hydrated lime and include relaxation of gradation requirements. Consideration of Subcmte Negative Vote by Greg L. Campbell – The task group did not agree with the comments by Mr. Campbell because language pertaining to the relaxation of gradation requirements is typical to other concrete masonry related standards. Additionally, allowing variations in gradation allows producers to best customize aggregates to improve properties of units. Since the negative by Mr. Speck was found to be persuasive, no official action was necessary on this item. Main Cmte Ballot C 15 (14-02) Item 19; Subcmte Ballot C15.03 (14-02) Item 18 ASTM C 15.03.05 Task Group on Unit Specifications Meeting Minutes December 11, 2014 Page 1 Consideration of Subcmte Comment by Michael D. Lewis – Comment was considered by task group and decided that no further action was necessary Other Business Weight Per Square Foot – A draft ballot item was presented to the task group for review to establish a separate subsection of weight per square foot and reference to the appendix. The task group agreed to the proposed language and to include the item on the next ballot. Modifications to C426 for MSV Units – A draft ballot item was presented to the task group for review to provide guidance regarding specimen requirements for shrinkage testing. Currently there are no requirements for the size of shrinkage specimens per ASTM C426, the draft ballot item proposes 3x12 inch specimens to be submitted for testing, and in the instance that MSV units fail to meet the size requirements, an alternative procedure of submitting molded beams for testing is also concluded. The task group agreed to the proposed language and to include the item on the next ballot. At time of delivery vs. 28-day requirement – At the time of the meeting, a finalized draft ballot item was not available. It was discussed the proposed ballot item would further delineate the materials requirements for MSV units between “at time of delivery” vs. a 28-day requirement. A final draft will be submitted to the task group to review before the next ballot. Unit Thickness Requirements – A thorough discussion took place concerning the unit thickness requirements of MSV units. Referencing the IBC and TMS codes, it appears that some may interpret the language to require all MSV units in a given profile be verified against maximum average thickness requirements. Currently ASTM C1670 only requires the testing of 3 units to ascertain the average unit thickness for a given profile. The consensus from the task group was that, although three units may not be a large enough sample size, it remains unclear the level of sampling that is necessary to ensure profile meet the unit thickness requirements. Rick Garagliano volunteered to work with the task group chair in determining options towards verifying unit thickness and the appropriate level of sampling needed. Adjournment The meeting was adjourned at 12:00 pm.

Review of Ballot Items Main Cmte Ballot C15 (14-02) Item 29 Revision of C1780-2014 Standard Practice for Installation Methods for Adhered Manufactured Stone Masonry Veneer Consideration of Main Cmte Negative by Donald Harvey Consideration of Main Cmte Negative by Gary Sturgeon Consideration of Main Cmte Negative by Michael Lewis Consideration of Main Cmte Negative by Rick Garagliano Consideration of Main Cmte Comment by Gregg Borchelt Consideration of Main Cmte Comment by Herb Nordmeyer Consideration of Main Cmte Comment by Dan Zechmeister o An in-depth discussion ensued over the topic of drainage wall systems. All negatives were considered, and while some negatives could be addressed as editorial revisions, it was decided to find Mr. Sturgeon persuasive under the rationale that methods for creating a wall drainage system should be included in a nonmandatory note. A revised ballot item was drafted by consensus during the meeting, with the intent to include the revised item on the next ballot. o Specific to Mr. Lewis’ negative, the task group found his negative to be unrelated and required no further action at this time. Main Cmte Ballot C15 (14-02) Item 30 Revision of C1780-2014 Standard Practice for Installation Methods for Adhered Manufactured Stone Masonry Veneer Consideration of Main Cmte Negative by Dan Zechmeister Consideration of Main Cmte Negative by Gary Sturgeon Consideration of Main Cmte Negative by Herb Nordmeyer o All negatives addressed the use of “when necessary” in the ballot item, related to analyzing the adequacy of the structural back up and attachments in existing wall assemblies for the installation of new veneer. The task group agreed to attempt to handle this as an editorial revision. Main Cmte Ballot C15 (14-02) Item 31 Revision of C1780-2014 Standard Practice for Installation Methods for Adhered Manufactured Stone Masonry Veneer Consideration of Main Cmte Negative by Gregg Borchelt – Negative was considered and determined to be persuasive and to be handled as an editorial change, under the rationale that scratch coats may be comprised of a material other than mortar. Consideration of Main Cmte Comment by Dean Cunningham – Comment was considered and the task group felt that no further action was required at this time. ASTM C 15.03.01 Task Group on Unit Specifications Meeting Minutes December 11, 2014 Page 1 Consideration of Main Cmte Comment by Rick Garagliano - Comment was considered and the task group felt that no further action was required at this time. Main Cmte Ballot C15 (14-02) Item 32 Revision of C1780-2014 Standard Practice for Installation Methods for Adhered Manufactured Stone Masonry Veneer Consideration of Main Cmte Negative by Nick Lang Consideration of Main Cmte Negative by Chris Little Consideration of Main Cmte Negative by Herb Nordmeyer Consideration of Main Cmte Comment by Gregg Borchelt Consideration of Main Cmte Comment by Dean Cunningham Consideration of Main Cmte Comment by Dominick Dowds Consideration of Main Cmte Comment by Rick Garagliano Consideration of Main Cmte Comment by Chris Hines o After a thorough discussion by the task group, all negatives were withdrawn under the agreement that editorial changes were made the ballot item concerning appropriate reference to explicitly state the inclusion of WRB in wall assemblies utilizing cement board as a backing substrate. Other Business Recommendation for paper back lath with furring strips – a potential ballot item was discussed concerning the requirement of using paper backed lathe for wall assemblies utilizing furring strips as a means to create a wall drainage system. The use of paper backed lathe would be an additional safe guard against water intrusion resulting from the cracks that form due to the variation in thickness of scratch coats where furring is present and not present. Paperbacked lath shall not qualify as an accepted layer of WRB. A draft of the ballot item will be submitted to the task group for review prior to inclusion on the next ballot. Variety of lath – Mr Hines brought to the attention of the task group the subject of applied liquid load bearing WRB systems. Further investigation into these seems was deemed necessary by the task group, prior to the drafting of any ballot item looking to include these systems. Interior vs Exterior Cement Board Application – Mr. Poerschke agreed to work on drafting a ballot item concerning different requirements for interior vs. exterior use of cement board as a backing substrate. A new items is expected for the next ballot cycle. Adjournment The meeting was adjourned at 9:30 pm.
