Contact Materials Engineering (FoE) for status) 1. SCOPE The materials defined by these specifications are ther
3、moplastic 20% glass fiber reinforced injection molded polypropylene compound. Material with recycled content should be used whenever feasible. 2. APPLICATION These specifications were released originally for material used for fuse junction panel box assembly, floor console substrate (interior non vi
4、sible components) and carbon canisters. 2.1 LIMITATIONS This material does not contain UV stabilizers, long term exposure to direct sunlight will cause chalking and loss of gloss. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to
5、 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 specification minimum, maximum or range
6、was established using 3 sigma data. For 2011 and beyond, refer to Table 1 for number of samples required for each test to establish specification limits. 3.1.2 WSS-M4D731-B1 is based on virgin materials. 3.1.3 WRS-M4D731-B2 This specification must contain -% of recycled content as defined by WRS-M99
7、P42-A1. The remaining portion of the material can come from virgin sources. 3.1.4 The use of regrind is permitted, for economic and environmental reasons, with compliance as indicated in WSS-M99P1111-A. 3.1.5 Materials used in interior applications must meet the requirements outlined in WSS-M99P2222
