Cerato, EU Controlled document at www.MATS Copyright 2013, Ford Global Technologies, LLC Page 1 of 6 POLYAMIDE (PA) 6, HEAT STABILIZED, 15% GLASS FIBER WSS-M4D1037-A1 REINFORCED BLOW MOLDING COMPOUND 1. SCOPE The
2、 material defined by this specification is a blow molding thermoplastic heat stabilized 15% glass fiber molding compound based on polyamide 6. 2. APPLICATION This specification was released originally for material used for air induction system such as dirty air ducts. 2.1 LIMITATIONS This material a
3、bsorbs 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 stabilizers, long term exposure to direct sunlight will cause chalking
4、 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 PRODUCTION MATERIALS Material suppliers and part producers must conform
5、 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, maximum or ran
6、ge 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 This specification is based on virgin materials. Materials with post-consumer, post-industrial, or repolymerised recycled materials as de
7、fined by WRS-M99P42-A1 are preferred and should be used whenever feasible. 3.1.3 The use of regrind is permitted for economic and environmental reasons with compliance as indicated in WSS-M99P1111-A. 3.1.4 Dry as molded: All test values indicated herein are based on material and specimens with moist
8、ure content not exceeding 0.2% except where noted (Moisture Conditioned) (test according to ISO 15512 Method B/ASTM D 6869). All test materials have to be sealed in moisture-proof containers and stored at 23 +/- 2 C ENGINEERING MATERIAL SPECIFICATION WSS-M4D1037-A1 Copyright 2013, Ford Global Techno
