14、ering Material Specifications. 4.1 Material(s) technical data sheet(s), Design Matrix, Design FMEA, and other material related processing information shall be made available for review prior to qualification testing. Process P-Diagram and plant specific Process FMEA shall be developed before the mat
15、erial can be introduced to a production facility. Under agreed-upon circumstances, certain previously submitted data may be applied to subsequent data submissions. In this case, the qualification requirements will depend on the degree of changes made to the material. The final test requirements shal
16、l be agreed upon between the responsible Materials Engineer and the supplier prior to testing ENGINEERING MATERIAL SPECIFICATION WSS-M3B82-A1/A2/A3 Copyright 2017, Ford Global Technologies, LLC Page 3 of 3 4.2 APPROVAL OF MATERIALS Suppliers desiring approval of their materials shall first obtain an
17、 expression of interest from Purchasing, Design or Product Development, and Materials Engineering. The supplier shall submit a completed copy of their laboratory test reports, signed by a qualified and authorized representative of the test facility, demonstrating full compliance with all the require
18、ments of the Material Specification. Tested material samples must be available for review upon request and kept for a minimum of one year. Upon request, the supplier will review the associated quality control documents (Process Failure Mode and Effects Analysis, Control Plans, Certification testing)
19、 with Ford. 4.3 SUPPLIERS ONGOING RESPONSIBILITY All materials must be equivalent in all characteristics to the material upon which approval was originally granted. Prior to making any changes to the material originally approved, whether or not such changes affect the materials ability to meet the s
20、pecification requirements, the supplier shall notify the affected Supplier Technical Assistance (STA), Purchasing, and Materials Engineering activities of the proposed changes (with reasons) by submission of a completed Suppliers Request for Engineering Approval, SREA. For parts and components using
21、 Ford Engineering Material Specifications, all samples tested to the specifications for Design Verification (DV), Production Verification (PV) and Production Part Approval Process (PPAP) sign off must be kept until Job 1. 4.4 RESTRICTED SUBSTANCE MANAGEMENT STANDARD Substance restrictions imposed by
22、 regulations or Company direction applies to the materials addressed by this document. The restrictions are identified in the Restricted Substance Management Standard WSS-M99P9999-A1 which is updated yearly. It is the suppliers responsibility to comply with this standard on a continuing basis throug
23、h IMDS and or GMAP reporting. 5. SUMMARY OF REVISIONS 2017 05 31 Removed WSS-M99P1111-A and added those requirements directly to the specification.
