4、n and shroud. WRS-M4D1029-A2 This specification was released originally for material containing post consumer or post industrial recycled resin content. 2.1 LIMITATIONS This material absorbs and retains moisture. Part design and tolerances must accommodate changes in part dimensions and physical pro

5、perties 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 suitable to direct long term exposure to engine coolant, or direct exposure

6、 to strong acids or bases. It is not suitable to use above 150 C. 3. REQUIREMENTS 3.1 APPROVED 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, o

7、r other documents. The list of approved sources is located within Ford at or available externally through a Ford Materials Engineer. Approval of new sources requires the completion of the latest version of the FMD template. Data should be submitted at the same time as the specification data package

8、. Only one FMD package is required per trade name approved, FMD is not required for each manufacturing site. FMD is required for new site approvals that do not have an existing FMD record.

All test materials have to be sealed in moisture

10、-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. 3.3 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS IR spectra and thermogr

11、ams from initial material approval shall constitute the reference standard and shall be kept on file at the designated material laboratory. The material supplier shall ensure that all future material supplied to the specification shall produce IR spectra and thermograms that correspond to the refere

12、nce standard when tested under the same conditions. 3.4 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS 3.4.1 Many 4D resin specifications prior to 2011 identified certain requirements with the symbol (*), which indicated that the mean and +/- 3 sigma values were to be reported. The specification min

13、imum, 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 WSS-M4D1029-A1 is based on virgin materials. 3.4.3 WRS-M4D1029-A2 must contain minimum 60% Sustainable Material (Post Consumer Recycled (PCR) and/or Po

14、st Industrial Recycled (PIR) content, as defined by WRS-M99P42-A1). Actual % to be reported as part of the data submission pack. 3.4.4 The use of regrind is permitted, for economic / environmental reasons. Part manufacturers using this specification must complete DV and PV testing with the allowable

15、 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 specific amount implies zero regrind) must be approved by Materials and PD Engineering through the formal Ford Motor Company process (SREA).

16、3.4.5 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, see paragraph 3.2) (test according to ISO 15512 Method B/ASTM D6869). All test materials have to be sealed in moisture-proof co

17、ntainers 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 +/- 2 C and 50 +/- 5% relative humidity.
