3、 15% MINERAL) REINFORCED MOLDING COMPOUND, 25% PCR AND/OR PIR CONTENT 1. SCOPE The material defined by this specification is a thermoplastic heat stabilized 25% glass fiber and 15% mineral reinforced molding compound based on polyamide 66. Material with recycled content should be used whenever feasi
4、ble. 2. APPLICATION WSS-M4D823-B1 This specification was released originally for material used for engine valve covers. WRS-M4D823-B2 This specification was released originally for materials containing post consumer or post industrial recycled content. 2.1 LIMITATIONS - This material absorbs and ret
5、ains 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 and los of
6、gloss. - This material is not suitable to direct long term exposure to engine coolant, or direct exposure to strong acids or bases. It is not suitable to use above 150C. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Compa
7、nys 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 range was establ
8、ished using 3 sigma data. For 2011 and beyond, refer to Table 1 for number of samples required for each test. 3.1.2 WSS-M4D823-B1 is based on virgin materials.

9、 must contain 25% 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. 3.1.4 The use of regrind is permitted for economic and environmental reasons with compliance as indicated in W
10、SS-M99P1111-A. 3.1.5 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). All test materials have to be sealed in moisture-proof conta
11、iners 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 below 133 kPa. Conduct tests in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5% relative humidity.
