2、CYCLED RESIN CONTENT 1. SCOPE The material defined by this specification is a thermoplastic 30% glass fiber/mineral reinforced molding compound based on polyamide 6. 2. APPLICATION This specification was released originally for intake manifold material containing post consumer or post industrial rec

3、ycled 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 UV stabilizers, long term e

4、xposure 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. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppli

5、ers 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 values were to be reported. The sp

6、ecification 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 100% Post Consumer Recycled (PCR) and/or Post Industrial Recycled (PIR) content as defined by WRS-M99P42-A1. The

7、remaining portion of the material can come from virgin sources. ENGINEERING MATERIAL SPECIFICATION WRS-M4D993-B3 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 indicated in Ford Engineering CAD

8、 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 drawing (no specification impli

9、es 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 Conditioned, see paragraph 3

10、.1.X) (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%, condition the material for a minimum of 16 h at 40 50 C at a redu

11、ced 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 conditioned to a moisture content

12、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 Criteria: Parts using this specificati

13、on shall meet the appropriate engine and underhood 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, but are not

14、 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 defined in ISO18

15、74-2. No annealing is allowed. See Table 1 for the number of samples required.
