4、on molding compound based on a 30% glass fiber reinforced, heat stabilized, cooling agent resistant polyamide 6,6. 2. APPLICATION These specifications were released originally for material used for parts of the engine cooling components. 2.1 LIMITATIONS This material absorbs and retains moisture. Pa

5、rt 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 stabilizers, long term exposure to direct sunlight will cause chalking and loss of gloss. 3. REQUIREM

6、ENTS 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 Many 4D resin specifications prior to 2011, identified certain requirements with the symbol (s), which ind

7、icated 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 WSS-M4D752-B1 is based on virgin materials. 3.1.3 WRS-M4D752-B2

8、 must contain 25% recycled content as defined by WRS-M99P42-A1 (post- consumer and/or post industrial recyclates and repolymerised recycled materials) The remaining portion of the material can come from virgin sources. 3.1.4 WRS-M4D752-B3 must contain 50% recycled content as defined by WRS-M99P42-A1
