SCOPE The ma
3、terial defined by this specification is a thermoplastic 10% glass fiber and 15% mineral filled, heat stabilized molding compound based on polyamide 6,6. 2. APPLICATION WSS-M4D366-B1 This specification was released originally for material used for engine cooling fan and shroud. WRS-M4D366-B2 This spe
4、cification was released originally for materials containing post consumer or post industrial recycled content. 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
5、 in the service/assembly environment. This material absorbs and retains moisture. Part design and tolerances must accommodate 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 PROD
6、UCTION 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 va
7、lues 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-M4D366-B1 is based on virgin materials. 3.1.3 WRS-M4D366-B2 must c
8、ontain 75% Post Consumer Recycled (PCR) and/or Post Industrial Recycled (PIR) content as defined by WRS-M99P42-A1. The remaining portion of the material can come from virgin sources.
