2、PIR RECYCLED RESIN CONTENT 1. SCOPE The material defined by this specification is a thermoplastic with approximately 30% glass fiber and 5% mineral reinforced molding compound based on polyamide 66. 2. APPLICATION This specification was released originally for cam cover materialscontaining post cons

3、umer 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 in the service/assembly environment. This material does not contain

4、UV stabilizers, long term exposure to direct sunlight 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 150oC. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUC

5、TION 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 valu

6、es 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. 3.1.2 Material must contain 50% Post Consumer Recycled (PCR) and/or Post Industrial Recycled (PIR) content as de

7、fined by WRS-M99P42-A1. The remaining portion of the material can come from virgin sources. ENGINEERING MATERIAL SPECIFICATION WRS-M4D1021-A1 Copyright 2014, Ford Global Technologies, LLC Page 2 of 7 3.1.3 The use of regrind is permitted, for economic / environmental reasons, with compliance as indi

8、cated 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 specified on the engineering drawing. Any changes to what is specified on the dr

9、awing (no specification implies zero regrind) must be approved by Materials and PD Engineering through the formal Ford Motor process (SREA). 3.1.4 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

10、 Conditioned, see paragraph 3.1.5) (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 for at least 24 h immediately after processing. If the moisture content exceeds 0.2%, conditioning the material for a mini

11、mum 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. Individual specimens shall not be removed from closed containers until immediately before testing. 3.1.5 Moisture Conditioned: The specimens shall be co

12、nditioned to a moisture content of 1.0 to 2.0 wt% moisture then place the specimens in standard atmosphere of 23 +/- 2 C and 50 +/- 5% relative humidity for at least 1 h before testing (according to ISO 1110). Moisture content shall be reported to verifly the moisture level. 3.1.6 Performance Criter

13、ia: Parts using this specification shall meet the appropriate performance specifications, WSS-M15P50-B. 3.1.7 As specified in WSS-M99P1111-A, paragraph 3.2, Ford Materials Engineering may request a Control Plan and Certificate of Analysis (CoA) containing lot testing requirements which must include,

14、 but are not limited to: Filler Content Impact Strength, Notched Charpy at 23C Flexural Modulus 3.2 SAMPLE PREPARATION Unless otherwise specified all tests shall be carried out on injection molded, one-end gated test specimens. The test specimens A and D shall be molded using molding conditions defi

15、ned in ISO1874-2. No annealing is allowed. See Table 1 for the number of samples required.
