14、all be rated after exposure using the AATCC Gray Scale for Evaluating Change in Color (10 Step). Production materials shall exhibit fade resistance qualities equal to or better than the master sample approved for production by the Interior Materials Engineering Section. 3.11.2 Fiber Deterioration No
15、 excessive deterioration of fibers or yarns after the above xenon arc exposure. The resistance to deterioration of production material shall be equal to or better than that exhibited by the master sample approved by the Interior Materials Engineering Section. Test Method: Firmly apply a piece of 3Ms
16、 Highland Brand 6200 Permanent Mending Tape to the surface of the exposed fabric (yarn). Then rapidly strip the tape and mount it on a sheet of light or dark cardstock which contrasts with the color of the fiber. Repeat the test with a new piece of tape on an unexposed sample and compare the length
17、and quantity of fibers removed by the tape. Report fiber deterioration if a significantly larger number of fibers (usually of shorter lengths) are removed from the exposed versus unexposed sample.

27、ls Engineering activity of the proposed changes and 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 addres
28、sed by this document. The restrictions 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
29、 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 a completed copy of their laboratory test reports, signed by a qualified and authorized representati
30、ve of the test facility, demonstrating 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 assessment of suitability for intended processes and/or applications.
