14、all be clearly designated on the engineering drawing. 3.17 SUPPLIERS RESPONSIBILITY All materials supplied to this 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, constructi

15、on, color, processing or labeling of the material originally approved under this specification, whether or not such changes affect the materials ability to meet the specification requirements, the Supplier shall notify Purchasing, Toxicology and the affected Materials Engineering activity of the pro

16、posed ch anges and obtain the written approval of the Materials Engineering activity. Test data, test samples and a 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 regulat

17、ions are defined in Engineering Materials Specification WSS - M99P9999 - A1. 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 o

18、f interest from 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, demo

19、nstrating full compliance with all the requirements of this specification (test results, not nominal values), the material designa tion and code number, and test specimens for Ford evaluation. Ford engineering approval of a material will be based on its performance to this specification and on an assessment of suitability for intended processes and/or applications. Upon approval, the material will be added to the Engineering Material Approved Source List.
