10、otifyPurchasing, Toxicology and t he affected Materials Engineering activity ofth e proposed changes and obtain the written approval of the MaterialsEn gineering activity. Test data, test samples and a new codeidentification are to be submitted with the request.Sub stance restrictions imposed by law

11、, regulations or Ford, apply to themateria ls addressed by this document. The restrictions are defined inEngin eering Material Specification WSS-M99P9999-A1, unless a differentsuf fix (e.g., A2 or A3) is specified on the engineering document for theapplication.4. APPROVAL OF MATERIALSMat erials defi

12、ned by this specification must have prior approval by theresponsible Materials Engineering activity. Suppliers desirin g approval of theirmaterial s shall first obtain an expression of interest from the affectedPurch asing, Design and Materials Engineering activity. Upon request, theSupplier shall s

13、ubmit to the affected Materials Engineering activity its ownlaboratory report to the specification (test results, not nominal values), themat erial designation and code number, and test specimens for Ford evaluation.Upon approv al, the material will be added to the Engineering Material ApprovedSource List.
