Contact for questions concerning Engineering Material Specifications. 4.1 APPROVAL OF MATERIALS Suppliers desiring approval of their materials shall first obtain an expression of interest from the affected Purchas
21、ing, Design and Materials Engineering Activity. Upon request, the Supplier shall submit to the affected Materials Engineering Activity a completed copy of their laboratory test reports, signed by a qualified and authorized representative of the test facility, demonstrating full compliance with all t
22、he requirements of this specification (test results, not nominal values), the material designation and code number, and test specimens for Ford evaluation. Fords engineering approval of a material will be based on its performance to this specification and on an assessment of suitability for intended
23、 processes and/or applications. Upon approval, the material will be added to the Engineering Material Approved Source List. 4.2 SUPPLIERS ONGOING RESPONSIBILITY All materials must be equivalent in all characteristics to the material upon which approval was originally granted. Prior to making any cha
24、nges to the material originally approved, whether or 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 reason
25、s) by submission of a completed Suppliers Request for 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) s
26、ign off must be kept until Job 1. 4.3 RESTRICTED SUBSTANCE MANAGEMENT STANDARD Substance restrictions imposed by 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
