Part design and tolerances must accommodate changes in part dimensions and physical properties due to moisture absorption or loss in the service/assembly environment. 3. REQUIREMENTS 3.1 APPROV
4、ED SOURCES This specification requires the use of approved sources. Only the sources identified on the Ford Approved Source List (ASL) can be used when this specification is listed on the drawing, CAD file, or other documents. The list of approved sources is located within Ford at or available exte
5、rnally through a Ford Materials Engineer. 3.2 CONDITIONING AND TEST CONDITIONS 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 D6869). All test materials
6、 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 reduced pressure below 133 kPa. Conduct tests in a controlled atmosphere of 23 +
7、/- 2 C and 50 +/- 5% relative humidity. Individual specimens shall not be removed from closed containers until immediately before testing 3.3 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS IR spectra and thermograms from initial material approval shall constitute the reference standard and shall
8、 be kept on file at the designated material laboratory.

10、ed. 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. 3.4.2 This specification is based on virgin material and does not allow the addition of recycled content (PIR/PCR). 3.4.3 The use of
11、 regrind is permitted, for economic / environmental reasons. 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 th
12、e drawing (no specific amount implies zero regrind) must be approved by Materials and PD Engineering through the formal Ford Motor Company process (SREA) or Engineering Notice. . 3.4.4 Dry as molded: All test values indicated herein are based on material and specimens with moisture content not excee

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 ma
14、terial 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. Individual specimens shall not be removed from closed containers until immediately before testing Moisture conditions results for Tensi
15、le Strength, Tensile Modulus, Charpy Impact, and Flexural Modulus can be found in the Ford Material Database. 3.4.5 Moisture Conditioned: The specimens shall be conditioned 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% re
16、lative humidity for at least 1 h before testing (according to ISO 1110). Moisture content shall be reported to verify the moisture level. 3.4.6 Performance Criteria: Parts using this specification shall meet the appropriate performance specifications, WSS-M15P4-H/Latest. Parts must fulfill applicabl
