All critical areas with respect to these properties shall be clearly designate
13、d on the engineering drawing. 3.4 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS Ford Motor Company, at its option, may conduct infrared and/or thermal analysis of material/parts supplied to this specification. The spectra established for initial approval shall constitute the reference standard
14、and shall be kept on file at the designated material laboratory. All samples shall produce spectra that correspond to the reference standard when tested under the same conditions as those specified on the master spectrum. 3.5 STATISTICAL PROCESS Suppliers must conform to the requirements of Ford Qua
15、lity System Standard Q-101. A mutually acceptable Control Plan as described therein is required for material/source approval. Appropriate statistical tools must be used to analyze process/product data so that variation in the final product is continuously reduced. 3.6 SUPPLIERS RESPONSIBILITY All ma
16、terials supplied to this specification must be equivalent in all characteristics to the material upon which approval was originally granted. ENGINEERING MATERIAL SPECIFICATION ESF-M4D405-C1/C2 WP 3948-b Page 4 of 5 Prior to making any change in the properties, composition, construction, color, proce
17、ssing 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 proposed changes an
18、d 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 restrictions are defined
19、 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 of interest from the a
20、ffected 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 compli
21、ance 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 suitabili
22、ty for intended processes and/or applications. Upon approval, the material will be added to the Engineering Material Approved Source List. 5.
