The IR spectra and thermograms established for initial approval sh
13、all constitute the reference standard and shall be kept on file at the designated material laboratory. All samples shall produce IR spectra and thermograms that correspond to the reference standard when tested under the same conditions. 3.5 STATISTICAL PROCESS Suppliers must conform to the requireme
14、nts of Ford Quality 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 RESPON
15、SIBILITY 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, construction, color, processing or labeling of the material originally approved under
16、 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 and obtain the written approval of the Materials Engineering
17、activity. Test data, test samples and a new code identification are to be submitted with the request. ENGINEERING MATERIAL SPECIFICATION ESF-M4D405-B/D/D2 WP 3948-b Page 4 of 5 Substance restrictions imposed by law, regulations or Ford, apply to the materials addressed by this document. The restrict
18、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 of int
19、erest 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, demonstra
20、ting full compliance 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 assessm
21、ent of suitability for intended processes and/or applications. Upon approval, the material will be added to the Engineering Material Approved Source List. 5 GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting the requirements of this specification.
