Bendix Requirements Guideline
There are currently 19 elements that are the requirements of PPAP.
The intent of this guideline is to give clarification to the Supplier of what the
Bendix expectations are for each element requirement.
General Comments/Suggestions:
•
All 19 requirements are to be addressed, regardless of level of submission.
•
Page 1 of the PPAP Submission Package is recommended to be an
introductory page. It should include: Part Name; Part Number; Drawing
Number; Engineering Change Level; Engineering Change Level Date;
Supplier Name; Supplier Code; Supplier Street Address, City, State and Zip
Code; Supplier Phone Number; Supplier Fax number; Customer Name
(BCVS), and the using plant that the supplier is submitting the PPAP
package to.
•
Any element requirement that is not included or does not apply is to have a
page stating such included under the appropriate tab in the PPAP submission
package.
•
Note that the requirements of AIAG PPAP Fourth Edition, Appendix H, applies to
BCVS products (Truck Industry-Specific Requirements).
•
The APQP Core Tools Forms diskette is available to guide the supplier through the
part approval process (contact your BCVS Supplier Quality Development
representative).
•
The supplier can expect to have the submitted PSW form, once approved
by Bendix, returned to them via fax (be sure to include appropriate fax
number on introduction page).
•
Production part approval records, regardless of submission level shall be
maintained for the length of time that the part is active plus one calendar
year.
•
All Drawings, Specs, and other supplemental information contained herein
as examples, is strictly for reference purposes only.
1. Design Records:
Hard copies of the following items are to be submitted with the PPAP package:
• Engineering Drawings
• Process, Material and Engineering Specifications
• Design Records are required for all components and details e.g. where the part is
a machined casting, the machining supplier is responsible to produce the design
records for the casting, which includes the Supplier’s approved Part Submission
Warrants and all Design Records for all sub-supplier parts.
• Where the design record is in electronic format, the supplier shall still provide a
hard copy of those documents.
As an example, reference the Bendix prints and associated specs included in this
document (element # 9, "Dimensional Results").
Note 1: For any saleable product there will be only one design record. The
design record may reference other documents making them part of the design
record.
Note 2: A single design record can represent multiple part or assembly
configurations.
Note 3: For parts identified as “black box”, the design record specifies the
interface and performance requirements.
Note 4: For parts identified as catalog parts, the design record may consist only
of a functional specification or a reference to a recognized industry standard.
Note 5: For bulk materials, the design record may include identification of raw
materials, formulations, processing steps and parameters, and final product
specifications or acceptance criteria.
•
Reporting of Part Material Composition shall be provided by the supplier when
required and this data must comply with all Bendix requirements.
•
Polymeric parts must be identified with the ISO symbols such as specified in ISO
11469 (Plastics) and/or ISO 1629 (Rubber & lattices). The following weight
criteria shall determine if the marking requirement is applicable:
- Plastic parts weighing at least 110g.
- Elastomeric parts weighing at least 220g.
2. Authorized Engineering Change Documents:
•
•
Examples include marked up drawings signed and approved by BCVS
Engineering, or MCRs where approval by BCVS Engineering has been obtained.
PPAPs are NOT to be submitted if the design requirements have not been met.
3. Customer Engineering Approval:
•
Bendix specifications may require suppliers to submit test results or samples for
evaluation by the BCVS Materials Department. Suppliers are responsible for
conforming to the requirements of BW specs either called out on BCVS
drawings, or as included as part of the Design Record prior to PPAP submission.
As an example, reference the Bendix spec, BW-128-P, section 6.0 included in
this document.

PROCESS SPECIFICATION BW-128-P
CHROMATE CHEMICAL CONVERSION FILM (ALODIZING)
FOR ALUMINUM ALLOYS
1.0
SCOPE
The purpose of this process is to produce a chemical chromate conversion film on
aluminum alloy parts to improve corrosion resistance and paint bonding
properties. This treatment shall be applied after all machining, stamping, bending
or other forming operations have been performed.
The coating will degrade at temperatures above 140° F (46°C) with subsequent
loss of corrosion resistance.
2.0
PROPERTIES
2.1
3.0
Parts treated according to this specification shall have a uniform iridescent
to brown adherent coating. A porous, powdery coating is not acceptable.
The process shall supply the corrosion resistance described under
Qualification Requirements.
PROCESS
3.1
The parts shall be placed in baskets in a manner which will minimize air
pockets and provide best drainage, when possible. Configuration of some
parts may leave an unavoidable air pocket. Certain parts alodized by outside
vendors may be rack coated in which case rack marks must be in a noncritical location. Sealing ring grooves and seat areas are typical critical
locations.
3.2
If the conversion coating bath is heated, stirring is recommended to avoid
breakdown of chemicals in the immediate vicinity of the heating coils.

4. Design FMEA:
•
•
•
If the supplier has design responsibility, the BCVS expectation is to have a
DFMEA in the AIAG compliant format submitted with the PPAP package.
If the supplier considers their design to be of a proprietary nature, a waiver for
this requirement must be obtained from the using plant quality function prior to
PPAP submission and is to be included under this tab of the PPAP package.
If the supplier does not have design responsibility, a page stating “Not
Applicable” is to be included under this tab of the PPAP package.
NOTE 1: A single Design FMEA may be applied to a family of similar parts.
NOTE 2: For Bulk Materials, see Appendix F. (AIAG 4 Edition)
5. Process Flow Diagrams:
•
The supplier must include a process flow diagram that clearly describes the
production process steps and sequences. The process flow step numbers
should match up with the Process FMEA and Control Plan step numbers.
NOTE: Process flow diagrams for “families” of similar parts are acceptable if the
new parts have been reviewed for commonality by the organization.
6. Process FMEA:
•
The supplier must include a process FMEA that is compliant to the AIAG
format.
•
PFMEAs are to include ALL process steps, e.g. receiving, incoming inspection,
labeling, shipping, etc.
•
All BCVS Special Characteristics must be included in the PFMEA.
•
High RPN process steps should include actions to reduce them.
NOTE 1: A single Process FMEA may be applied to a process
manufacturing a family of similar parts or materials if reviewed for
commonality by the supplier.
NOTE 2: For Bulk Materials, see Appendix F. (AIAG 4th Edition)
7. Control Plan:
•
Control plans for “families” of similar parts are acceptable if the new parts have been
reviewed for appropriate commonality.
•
Control plan approval by BCVS prior to PPAP package submission is NOT
required.
•
Regardless of the form used by the supplier, all elements of AIAG APQP
format must be addressed.
•
All BCVS Special Characteristics must be included in the control plan.
Note 1: Control plans for ‘families of parts are acceptable if the new parts
have been reviewed for commonality by the organization.
Note 2: Control Plan approval may be required by Bendix.
8. Measurement System Analysis Studies:
•
MSA studies are to be submitted for all gages or families of gages used to
measure the applicable product/process characteristic of the initial process
capability study.
•
Where Special Characteristic requirements apply, valid MSA’s for each
specific gage used to measure the Special Characteristics must be
submitted. MSA studies for gage families are NOT acceptable.
NOTE: Gage R & R acceptability criteria are defined in the
Measurement Systems Analysis reference manual.
9. Dimensional Results:
•
•
Dimensional results are to be included for each unique manufacturing cell or
production line and all cavities, molds, patterns, or dies.
It is expected to have a "ballooned" drawing included with the PPAP package.
Each ballooned element of the drawing is to be numbered and correspond to the
numbering sequence on the Dimensional Results form.
As an example, reference the drawing 298725 and Dimensional Results included
in this document.
•
•
•
•
•
Actual dimensional results are to be shown in the Supplier Measurement Results
column of the Dimensional Results form. Write down the actual reading (or
range) obtained (NOT "OK / Not OK").
The OK/Not OK boxes are to be checked appropriately to indicate conformance
of the measurements obtained to the Design Record requirements.
Drawing notes are to be included on the Dimensional Results form, along with
evaluation results.
Dimensional results of sub-components are to be included in the PPAP
submission package (see element # 1, "Design Records of Saleable Product").
Embedded dimensional requirements within BW specifications are to be
recorded.
As an example, reference the Bendix spec, BW-111-ES for flash, ejector pins,
surface finish, etc. requirements included in this document.
•
The organization (supplier) shall identify one of the parts measured as the
“master sample”. (see section 15)
NOTE: The Dimensional Results form in Appendix C (PPAP 4th Edition) shall be
utilized for this purpose.

SCOPE:
This Standard establishes the Bendix Commercial Vehicle Systems L.L.C. (BCVS)
acceptance limit for aluminum and zinc die castings and is a supplement to the
individual casting drawing. All requirements herein must be met, in addition to all
other requirements of the applicable drawing.
If there is a conflict between BW-111-ES and the drawing, the drawing shall prevail.
2.0
PURPOSE:
The purpose of this document is to define the BCVS acceptance level of die castings
intended for production use and to serve as an aid to the casting suppliers.

3.2
BW-107-ES Date Code Requirements.
GENERAL:
4.1
In those cases where a special flatness is required, it will be specified on the
drawing. Otherwise NADCA Standards shall prevail.
4.2
Mastering surfaces will be specified on the casting drawing when required.
These are cast surfaces, which are used to locate the casting in a machining
fixture for first machining operations.
4.3
Die casters who intend to machine castings to obtain the specified as cast
dimensions must note this fact on their quotation sheet.
4.4
Key surfaces to be machined will be identified per Section 6.4 on both the
casting and machining drawings1. These machining drawings must be provided
to the die caster by SBM as part of the quotation process.
4.5
Unless otherwise noted on the drawing, measurements for concentricity,
perpendicularity, runout, length, etc. shall not include parting lines, gate marks
or flash.

5.0
POROSITY:
Die castings are never entirely free of porosity. However, this standard will attempt to
define the degree of porosity and imperfections permitted based on the functional need
of both the “as cast” and “as machined” part as it pertains to their use in the BCVS
organization.
5.1
6.0
Definitions:
5.1.1
Porosity: Irregular shaped voids in the die cast part as a result of gas
bubbles, impurities, shrinkage, movement of base material, etc.
5.1.2
Pore Size: The size of the porosity is defined as the largest dimension
of the pore; i.e. major diameter of a spherical or irregular shaped void,
or the longest dimensions of a crack-like void. Typical descriptions
are “pin-point” which are pores .020” (0.5mm) diameter or smaller,
and “pit type” which are pores larger than .020” (0.5mm) diameter.
5.1.3
Surface Porosity: Surface porosity is defined as any void occurring at
a surface, either cast or machined.
5.1.4
Chain Porosity: Chain porosity is a set of interconnected pores
forming a chain-like void.
REQUIREMENTS:
6.1
Working Pressure: Castings used in pneumatic control valves are designed for a
working pressure of 150 psi and must withstand a proof test2 of 600 psi without
failure. BCVS reserves the right to test components on production line or
laboratory equipment using either finished components or assemblies.
6.2
Leakage: The casting must be free of porosity, which may cause external
leakage.
BCVS reserves the right to test components on production line or laboratory
equipment using either finished components or assemblies.
Leakage determined to stem from air passage through gates, parting lines,
casting skin or other areas created by the casting process3 will be grounds for
rejection.
2
Frequency of proof testing is determined by statistical process control. Consult BCVS quality or 6 sigma
departments for further details.
3
Casting Process is further defined as the three processes of casting, annealing and cool down used in the
creation of the part. Optimized gating, reduced air entrapment, fewer cold shuts, reduced porosity and
optimized shot profiles are some of the parameters that can be optimized through the use of computer
simulation. Source: www/magmasoft.com or equal.
BW-111-ES
4 of 6
6.3
Porosity Levels: The level of porosity permitted will be determined by BCVS
and more than one level may be specified on a part. The level of porosity for
unspecified areas will be covered by a note on the casting and machining
drawings.
6.4
Machined Surfaces:
6.4.1
Key machined surfaces will be designated on the casting and
machining drawings by using the symbol K-1 or K-2. These surfaces
must meet porosity LEVEL 1 or porosity LEVEL 2 requirements
respectively to a depth, which will allow machining to the finished
dimension. For interpretation of these porosity levels refer to
Manufacturing Acceptance Standard Engineering Die Cast
Specification BW-111-ES Supplement.
K-1: Machined surfaces shall not have pores larger than those in Level
1 or a frequency of pore occurrence greater than that of Level 1.
K-2: Machined Surfaces shall not have pores larger than those in
Level 2 or a frequency of pore occurrence greater than that of Level 2.
6.4.2
6.5
Porosity Greater in Excess Level 3: In some instances porosity in
excess of Level 3 will be exposed in a non-critical machined zone of a
casting. When it is determined by BCVS engineering that strength and
gas tightness are not compromised for the section in question, porosity
in excess of Level 3 will be acceptable. In addition, the porosity
requirement does not apply to those cross sectional areas of solid
material that are 1/8” or greater from all adjacent surfaces; for
example, material that could be cored away, if practical. Such
exceptions should be noted in an NCM and added to the drawing if
deemed appropriate by BCVS engineering.
Surface Condition as Cast:
“As Cast” sealing surfaces will be identified on the casting drawing by the
symbol S. No parting lines or die drag marks will be permitted on these
surfaces. The surface finish, whether as a result of surface porosity, die
checking or abrasive (blast) cleaning, shall not exceed 160 microinches.
Unless otherwise specified on the casting drawing, the condition of all cast
surfaces must meet North American Die Casting Association Standard NADCA
G-6-6-94 Class 1. Identifying marks on castings must be completely legible
following cleaning and deburring procedures. If questions occur as to legibility,
they should be directed to BCVS engineering or quality department.

Flash4 Control:
Unless otherwise specified, the following requirements must be met:
6.6.1
Parting Line/External Profile Flash must be within 0.4 mm (.015”) of
the die casting surface (Ref: NADCA G-6-5-94).
6.6.2
Cored Hole and Insert Flash must be within 0.25 mm (.010”) of the die
cast surface (Ref: NADCA G-6-5-94).
6.6.3
Ejector Pin Flash must not exceed 0.60 mm (0.025”) height.
6.6.4
Removal of Flash at the Bottom of a Cored Hole: A 0.8 mm (.030”)
breakout around a trimmed hole is permitted.
6.6.5

Previous Special (Classified) Characteristics
This document obsoletes the Star, Shield, and Delta Classified Characteristics. These characteristics are still valid
for existing drawings, but they cannot be used on new or revised drawings after release of this document. These
characteristics must be replaced with the new S/C or C/C symbol when a drawing is updated. The circle c/c
(obsolete from a previous revision) must either be updated to a new symbol or removed.
2.0
Restrictions
2.1 Fan Drive Exception: This procedure is not applicable for Fan Drive components / assemblies and assembly
processes. Special (Classified) Characteristics assigned to the fan drive drawings were based on other criteria, not
driven by DFMEA. Therefore, the Special Characteristics assigned to fan drive component / assemblies and
processes are not valid nor covered by this document.
3.0
Concessions for Non-Conforming Material (NCM)
3.1 No concessions are allowed for Star, Shield, and Delta symbols.
3.2 Concessions are allowed for circle c/c only with signed approval from the Product Engineer and the Customer
(if applicable).
4.0
Control
4.1 All Star, Shield, and Delta symbols are to be produced on a process with a minimum short-term capability of
1.67 Cpk (±6 Sigma). The long-term capability of the process must be monitored and maintain a 1.33 Ppk
minimum.
4.2 All characteristics not meeting capability requirements must be checked 100% on a device (test stand or
inspection equipment) that is free from operator interpretation.
4.3 Any Special Characteristic that does not meet capability must have a written plan for improved capability
established and approved by the Plant Quality Manager.
4.4 The control method must be detailed in the control plan for all Special Characteristics. Specific controls are
detailed in Procedure DPP 6.2.2.2. The required sample size will follow the latest edition of AIAG PPAP manual or
as agreed upon in the control plan.
4.5 Circle c/c characteristics still on drawings must have an initial short term capability Cpk of 1.33. It is not
necessary to track long term capability.
5.0
