19、Nothing in this standard supercedes applicable laws and regulations.Note: In the event of conflict between the English and domestic language, the English language shall takeprecedence.Note: In this document, the word shall is a requirement and the word should is a recommendation.Note: In this docume
20、nt, the word label refers to all marking methods and technologies (including all methods inAppendix L).Note: All label samples and examples used in this document as for demonstration purposes only.1.1 Scope. This standard defines the bar code symbologies, data content, and label/Direct Part Marking(
21、DPM) layout for parts, components, assemblies, and modules used in the manufacturing of GM vehicles. Thisstandard also defines the performance standards for printed bar codes and Direct Part Marking. This standarddoes not apply to packaging labels or service parts labels.1.2 Mission/Theme. Not appli
22、cable.1.3 Classification. Not applicable.1.4 New Sourced Parts, Components, Assemblies, and Modules. All parts, components, assemblies, ormodules with KCDS codes TRA, AVG and/or VER shall comply with this document. When scanning is used forCOM components or assemblies, this standard shall apply.1.5
23、Carryover Parts, Components, Assemblies, and Modules. Linear 1D Bar Code formats as specified inGM1737 are allowed on carryover scanned parts, components, assemblies or modules until the beginning ofMY2014. See NOA QLT196B for additional information. See Appendix H for Linear Bar Code referenceinfor
24、mation.1.6 Control Module Software. Control Module Software shall comply with GMW4710. New data structureshall go into effect beginning with Global B Architecture or upon new part sourcing for MY14.1.7 Additional Label Content. This specification defines only TRACE/ERROR-PROOFING REQUIREMENTSfor lab
25、els and Direct Marked Parts (DPM). GM MAY allow additional information on the label / DPM under thefollowing conditions:x complies with all applicable GMWs and regulationsx is visually separated / distinct from traceability / error proofing contentx does NOT contain additional bar codes (only GM-req
26、uired bar code is allowed unless others are requiredby law)x does NOT interfere with bar code scannabilityx agreed to by General Motors via the CG2503 approval process1.8 Reasons for Bar Code Scanning.1.8.1 Traceability. Traceability refers to all categories of GM defined component tracking that req
27、uire barcodes (i.e. includes TRA, AVG and/or VER). The primary purpose of traceability is to precisely identify thevehicles (VIN/trace number) involved in a spill or potential field action. Product Engineering is responsible fordefining which parts, components, assemblies, and modules require tracea
28、bility.1.8.2 Error Proofing. Error proofing provides the capability to validate the correct part/component/module/assembly has been installed on the vehicle.2 ReferencesNote: Only the latest approved standards are applicable unless otherwise specified.2.1 External Standards/Specifications.ANSI MH 10

34、l Rights ReservedJune 2013 Page 7 of 52DFMEA: Design Failure Mode Effects AnalysisBar codes may be used for error-proofing purposes; however, all other possible error-proofing alternativesshould be considered first due to the cost associated with bar codes and scanning. Parts, components,assemblies
35、and modules identified by Manufacturing Engineering through the Process Failure Mode andEffects Analysis (PFMEA) as sensitive to selection error may require a bar code for electronic verification. TheManufacturing Engineer will initiate a PRTS to communicate to Product Engineering the need to add th
36、e barcode. The Component DRE must fill out a CG2503 if a traceability or error-proofing bar code is required andinitiate an EWO as appropriate.3.2 Label/Mark Anatomy. The label/mark shall be constructed in a layout most suitable for the part,component, assembly, or module. The location and orientati
37、on of the symbol may be critical for applicationsusing automated fixed mount scanners. The Traceability Label/DPM format must be used for parts withtraceability requirements. Examples shown in this document are for illustration purposes only and are not to beconstrued as specifications. Note that da
38、ta identifiers such as Y, P, 12V, T, C, etc. shall not be printed on thelabel in human-readable form.3.2.1 Human-Readable Content Requirements for Traceability (see Appendix J for Powertrain). Therequirements for trace information shall include:x GM-required 2D Bar Codex GM assigned 8-digit part num
39、berx GM assigned compressed VPPS code with the last digit representing part location (see Appendix C2)x Manufacturing or assembly sites Data Universal Numbering System (DUNS) identificationx The 16-character traceability structure where L=Line, S=Shift, YY=Year, DDD=Julian Date (seeAppendix B for Ju
40、lian Calendars) and the last 9 characters (last 8 for lot/batch) are supplier-defined data.The Trace Code can be alpha and/or numeric.Figure 1: Illustration of a Serialized Traceability Label/DPMFigure 2: Illustration of a Lot/Batch Traceability Label/DPMFigure 3: Anatomy of a Label/DPM with a Symbo

45、les. Reference GMW4710 for the method to program electronic modules withtraceability information. Exterior labeling of electronic modules shall conform to the traceability structure asdetailed in paragraph 3.2.1 except for carryover electronic parts. Carryover electronic parts shall use theformat de

The last nine characters of the traceability code are definedaccording to Appendix J. See Appendix J for additional information.3.2.6 Tire Trace Data. See Appendix
47、 K for Tire Data trace syntax.3.3 Bar code Symbologies and Encodation. Bar code symbologies shall consist of the proper data syntax,data identifiers, control characters, and data fields. See Appendix E, H and J for additional information on barcode symbology and proper encodation.3.3.1 Bar Code Symb
48、ology. The information in this section applies to the two-dimensional (2D) bar codesymbologies defined in this Standard. Data Matrix (preferred symbology) ISO/IEC 16022 SymbologySpecification (Appendix D) or QR Code (with GM approval) ISO/IEC 18004, Symbology Specification, shall beused (Figure 5).
49、QR Codes provide decreased error correction, hence, Data Matrix is the preferred symbology.Figure 5: Two-Dimensional (2D) Symbologies Data Matrix (Preferred) and QR CodeThe data syntax structure used for Message Header, etc. is defined by ISO/IEC 15434.
