1、 ENGINEERING MATERIAL SPECIFICATION Date Action Revisions Rev 00 2013 05 10 Released V Cerato, FOE Controlled document at www.MATS Copyright 2013, Ford Global Technologies, LLC Page 1 of 6 POLYAMIDE (PA) 6, HEAT STABILIZED 35% GLASS WSS-M4D1038-A1 FIBER REINFORCED MOLDING COMPOUND 1. SCOPE The mater
2、ials defined by this specification are 35% glass fiber reinforced, heat stabilized polyamide 6 molding compounds. 2. APPLICATION This specification was released originally for material used for intake manifolds and GOR/FEM. 2.1 LIMITATIONS This material absorbs and retains moisture. Part design and
3、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. This material is not suit
4、able for direct 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 must conform to the Companys Standard Requirements For P
5、roduction 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 range was established using 3 sigma data. For 2
6、011 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, however materials with recycled content as defined by WRS-M99P42-A1 (post-consumer and/or post-industrial recyclates and repolymeris
7、ed recycled materials) should be used whenever technically feasible and following all materials and PV testing required by Ford Materials Engineering. 3.1.3 The use of regrind is permitted, for economic / environmental reasons, with compliance as indicated in Ford Engineering CAD and Drafting Standa
8、rds E-4. 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 Conditioned) (test according to ISO 15512 Method B/ASTM D 6869).

9、Ford Global Technologies, LLC Page 2 of 6 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 reduced pressure
10、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. 3.2 SAMPLE PREPARATION Unless otherwise specified all tests shall be carried out on injection mold
11、ed, one-end gated test specimens. The test specimens A and D shall be molded using molding conditions defined in ISO 1874-2. See Table 1 for the number of samples required. Specimens shall be as follows: Specimen A 150 minimum x 10 x 4.0 +/- 0.2 mm (ISO 527-2, Specimen Type 1A) Specimen B 355 x 100
