NCMA Antitrust Policy
The antitrust laws are the rules under which our competitive economic system operates. 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.

c.

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.

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.

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.

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

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.

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.

NCMA Draft Strategic Plan for
Manufactured Stone
Draft January 26, 2015
MISSION – NCMA expands the marketplace for manufactured stone veneer products by advancing,
promoting and protecting the common interests of its members.
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. Effectively establish NCMA as the technical authority on manufactured and maintain an external
image as a competent and objective industry advocate.
2. Advocate safe, economical, and sustainable solutions.
3. Focus NCMA marketing efforts on providing tools and resources from the national level for more
effective use and implementation by members at the state and regional level.
4. Ensure that association work plan is tactically feasible and balanced against available resources
and practical expectations.
POSSIBLE FUTURE PROGRAMS– The following is a list of programs and objectives that could be
considered by the industry at a future date, but are not currently in the work plan for the Association
through 2015. This list is not prioritized, and is intended only as a summary of potential activities that
have been discussed by the Manufactured Stone Segment, and could be considered as future work
items should the Market Segment find value in the future.

SUBJECT: Potential Revisions to the Acceptance Criteria for Precast Stone Veneer, Subject AC51-1214-R1 (EL/BJ)
To Whom It May Concern:
Thank you for the opportunity to provide input on potential changes to ICC-ES AC-51. 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.

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.

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.

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.

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.

 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.

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.

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.
