13、n or Product Development, and Materials Engineering. The supplier shall submit a completed copy of their laboratory test reports, signed by a qualified and authorized ENGINEERING MATERIAL SPECIFICATION WSS-M3H138-A Copyright 2015, Ford Global Technologies, LLC Page 3 of 4 representative of the test
14、facility, demonstrating full compliance with all the requirements 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
15、 and Effects Analysis, Control Plans, Certification testing) 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
16、 not such changes affect the materials ability to meet the specification 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 fo
17、r Engineering Approval, SREA. For parts and components using 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 SUB
