APPLICATION These specifications were released originally for material used f

5、or engine NVH and beauty covers. 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 stabil

6、izers, 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 150C. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCT

7、ION 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 sigma value

8、s 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-M4D968-B1 is based on virgin materials. 3.1.3 WRS-M4D968-B2 must contain 25% recycled content as defi

9、ned 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.
