ENGINEERING MATERIAL SPECIFICATION ESF-M4D405-C3 WP 3948-bPage 3 of 3 3.8 SUPPLIERS RESPONSIBILITY All materials supplied to this
13、specification must be equivalent in all characteristics to the material upon which approval was originally granted. Prior to making any change in the properties, composition, construction, color, processing or labeling of the material originally approved under this specification, whether or not such
14、 changes affect the materials ability to meet the specification requirements, the Supplier shall notify Purchasing, Toxicology and the affected Materials Engineering activity of the proposed changes and obtain the written approval of the Materials Engineering activity. Test data, test samples and a
15、new code identification are to be submitted with the request. Substance restrictions imposed by law, regulations or Ford, apply to the materials addressed by this document. The restrictions are defined in Engineering Material Specification WSS-M99P9999-A1, unless a different suffix (e.g., A2 or A3)
16、is specified on the engineering document for the application. 4. APPROVAL OF MATERIALS Materials defined by this specification must have prior approval by the responsible Materials Engineering activity. Suppliers desiring approval of their materials shall first obtain an expression of interest from
17、the affected Purchasing, 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 c
18、ompliance with all the 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 suit
19、ability for intended processes and/or applications. Upon approval, the material will be added to the Engineering Material Approved Source List. 5.
