9、ior to making any change in the properties, composition,construction, color, processing or labeling of the materialoriginally approved under this specification, whether or not suchchanges affect the materials ability to meet the specificationrequirements, the Supplier shall notify Purchasing, Toxico

10、logy andthe affected Materials Engineering activity of the proposed changesand obtain the written approval of the Materials Engineeringactivity. Test data, test samples and a new code identification areto be submitted with the request.Substance restrictions imposed by law, regulations or Ford, apply

11、to the materials addressed by this document. The regulations aredefined in Engineering Materials Specification WSS-M99P9999-A1.4. APPROVAL OF MATERIALSMaterials defined by this specification must have prior approval by theresponsible Materials Engineering activity. Suppliers desiring approvalof thei

12、r materials shall first obtain an expression of interest from theaffected Purchasing, Design and Materials Engineering activity. Uponrequest, the Supplier shall submit to the affected Materials Engineeringactivity a completed copy of their laboratory test reports, signed by aqualified and authorized

13、 representative of the test facility,demonstrating full compliance with all the requirements of thisspecification (test results, not nominal values), the materialdesignation and code number, and test specimens for Ford evaluation. Fords engineering approval of a material will be based on itsperforma

14、nce to this specification and on an assessment of suitabilityfor intended processes and/or applications. Upon approval, the materialwill be added to the Engineering Material Approved Source List.ENGINEERING MATERIAL SPECIFICATIONWSS-M14J513-AWP 3948-b Page 3 of 35. GENERAL INFORMATIONThe information
