ENGINEERING MATERIAL SPECIFICATION ESE-M8G182-A Page 4 of 4 4. APPROVAL OF MATERIALS: Materials defined by this specification must have prior

17、 approval by the responsible Materials Engineering activity. Suppliers desiring approval of their materials shall first obtain an expression of interest from the affected Purchasing, Design and Materials Engineering activity. Upon request, the Supplier shall submit to the affected Materials Engineering activity its own laboratory report to the specification (test results, not nominal values), the material designation and code number, and test specimens for Ford evaluation. Upon approval, the material will be added to the Engineering Material Approved Source List.
