3、atex backcoating. WSB-M3H103-B2 is not backcoated. 2. APPLICATION These materials are intended for package tray use only. The WSB-M3H103-B1 specification was released originally for material used as a package tray cover for the 1994 Mark VIII. The WSB-M3H103-B2 specification was released originallly
4、 for material used as a package tray cover for the 1995 Continental. This material must always be bonded 100 % to another material to form a composite, and the composite must not burn in excess of 100 mm/minute. 3. REQUIREMENTS In addition to the requirements listed herein, the end-item carpet assem
5、bly (molded or otherwise fabricated), shall meet all the applicable requirements of WSB-M15P6-C performance specification for package tray assemblies. 3.1 STATISTICAL PROCESS Suppliers must conform to the requirements of Ford Quality System Standard Q-101. A mutually acceptable Control Plan as descr
6、ibed 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.

16、3.13.1 Resistance to Fade, min Rating 3 (SAE J1885, 488.8 kJ/m2, and AATCC Evaluation Procedure 1) The material shall 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
17、Master Sample approved for production by the responsible Materials Engineering Activity. 3.13.2 Fiber Deterioration No excessive deterioration of fibers or yarns after the above xenon arc exposure per para 3.13.1.

Test Method: Firmly apply a piece of 3Ms Highland Brand 6200 Permanent Mending Tape to the surface of the exposed fabric (fibers). Then rapidly strip the tape and mount it on a sheet of light or dark ca
19、rd stock which contrasts with the color of the fiber. Repeat the test with a new piece of tape on a unexposed sample and compare the length 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
