SCOPE The materials defined b
3、y this specification are 30% glass fiber reinforced, heat stabilized polyamide 6 molding compounds. Material with recycled content should be used whenever feasible. 2. APPLICATION This specification was released originally for material used for intake manifolds and GOR/FEM. This material is formulat
4、ed to have enhanced welding properties. 2.1 LIMITATIONS This material absorbs and retains moisture. Part design and tolerances must accommodate changes in part dimensions and physical properties due to moisture absorption or loss in the service/assembly environment. This material does not contain UV
5、 stabilizers, long term exposure to direct sunlight will cause chalking and loss of gloss. This material is not suitable for direct long term exposure to engine coolant, or direct exposure to strong acids or bases. It is not suitable for use above 150 C. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR
6、 PRODUCTION MATERIALS Material suppliers and 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 sig
7、ma values were to be reported. The specification 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 to establish specification limits. 3.1.2 WSS-M4D993-B1 is based on virgin materials. 3.1.3 WRS-M4D993-B2 m
