2、NG COMPOUND 1. SCOPE The material defined by this specification is a thermoplastic 35% glass fiber reinforced impact modified molding compound based on polyamide 66. 2. APPLICATION This specification was released originally for material used for the housing transmission control selector. 2.1 LIMITAT
3、IONS 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 materialdoes not contain UV stabilizers, long term exposure to direct sunlight
4、will cause chalking or loss of gloss. This material is not suitable to 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 PRODUCTION MATERIALS Material suppliers and part producers m
5、ust 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 values were to be reported. The specification minimum, max
6、imum or range was established using 3 sigma data. For 2011 and beyond, refer to Table 1 for number of samples required for each test. 3.1.2 Dry as molded: All test values indicated herein are based on material and specimens with moisture content not exceeding 0.2% except where noted (Moisture Condit
7、ioned) (test according to ISO 15512 Method B/ASTM D6869). All test materials have to be sealed in moisture-proof containers and stored at 23 +/- 2 C for at least 24 h immediately after processing. If the moisture content exceeds 0.2%, conditioning the material for a minimum of 16 h at 40 50 C at a r
8、educed pressure below 133 kPa. Conduct tests in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5% relative humidity. Individual specimens shall not be removed from closed containers until immediately before testing. ENGINEERING MATERIAL SPECIFICATION WSS-M4D703-B1 Copyright 2014, Ford Global Techn
9、ologies, LLC Page 2 of 7 3.1.3 This specification is based on virgin 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. 3.1.4 The use of re
10、grind is permitted, for economic / environmental reasons, with compliance as indicated in Ford Engineering CAD and Drafting Standard E-4. Part manufacturers using this specification must complete DV and PV testing with the allowable amount of regrind and the maximum allowable regrind content must be
11、 specified on the engineering drawing. Any changes to what is specified on the drawing (no specification implies zero regrind) must be approved by Materials and PD Engineering through the formal Ford Motor process (SREA). 3.1.5 Performance Criteria: Parts using this specification shall meet the appr
