2、1 FILLED, COLOR PIGMENTED, MOLDING COMPOUND, INTERIOR 1 SCOPE The material defined by this specification is a molding compound based on polypropylene copolymer, mineral filled, molded-in-color, for unpainted interior applications. 2 APPLICATION This specification was released originally for material
3、 used for interior trim applications. 2.1 LIMITATIONS This material should not be used in safety relevant locations such as locations in which vehicle crash forces or airbag deployment could cause part breakage. 3 REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and
4、 part producers must conform to the Companys Standard Requirements for Production Materials (WSS-M99P1111-A). 3.1.1 Many 4D resin specifications prior to 2011, identified certain requirements with the symbol (s), which indicated that the mean and +/- 3 sigma values were to be reported. The specifica
5、tion minimum, maximum or range was established using 3 sigma data. For 2011 and beyond, refer to Table 1 for number of samples required for each test. 3.1.2 This specification is based on virgin materials, however materials with recycled content as defined by WRS-M99P42-A1 (post-consumer and/or post
6、industrial recyclates and repolymerised recycled materials) should be used whenever technically feasible and following all materials and PV testing required by Ford Materials Engineering. 3.1.3 The use of regrind is permitted, for economic / environmental reasons, with compliance as indicated in For
7、d Engineering CAD and Drafting Standard E-4 3.1.4 Materials used in interior applications must meet the requirements outlined in WSS-M99P2222-D1/Latest, Performance, Vehicle Interior Environment Quality Material/Component Requirements. Data must be included in material submission package. 3.1.5 Perf
