SCOPE The material defined by this specification is a heat stabilized polyamide 66 molding compound. 2. APPLICATION WSS-M4D648-B1
3、material is being released for non-visible applications( interior, body and underhood). WSS-M4D648-B2 material is being released for molded in color interior applications. 2.1 LIMITATIONS This material absorbs and retains moisture. Part design and tolerances must accommodate changes in part dimensio
4、ns and physical properties due to moisture absorption or loss in the service/assembly environment. B1 suffix only: This material typically does not contain UV stabilizers, long term exposure to direct sunlight will cause chalking and loss of gloss without suitable additives. This material is not sui
5、table for long term exposure to engine coolant, or direct exposure to strong acids or bases. It is not suitable for use above 155 C. For B2 only. Must be tested to WSS-M99P2222 D1/Latest, Performance, Vehicle Interior Environment Quality Material/Component Requirements if the part exceeds 100 cm2 or
6、 100 g. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.1.1 Note: Many 4D resin specifications prior to 2011, identified certain requirements with
7、the symbol (s), which indicated that the mean and +/- 3 sigma values were to be reported. The specification minimum, maximum or range was established using 3 sigma values. 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
8、materials, however materials with recycled content as defined by WRS-M99P42-A1 (post-consumer and/or post 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
9、The use of regrind is permitted, for economic / environmental reasons, with compliance as indicated in Ford Engineering CAD and Drafting Standard E-4.
