WRS-M4D578-B2 This specification was released originally for materials used for applications containing

5、post-consumer or postindustrial recycled resin 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

6、 not contain UV stabilizers, long term exposure to direct sunlight will cause chalking and loss of gloss. This material is not suitable for direct 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 APPROVED S

9、D Molders not on the CMB program or regions without CMB are required to use materials listed on the Ford Approved Source List (ASL), and are encouraged to use the CMB sources listed above. Only the sources identified on the Approved Source List can be used when this specification is listed on the dr

10、awing, CAD file, or 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 specific

11、ation data package. 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 3.2 CONDITIONING AND TEST CONDITIONS All test values indicated herein are based on material an

12、d 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 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

13、 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. Individual specimens shall not be removed from closed containers until immediately before testin

14、g 3.3 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS IR spectra and thermograms 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 spec

15、ification shall produce IR spectra and thermograms that correspond to the reference 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 (s), which indicate

16、d that the mean and +/- 3 sigma values 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. 3.4.2 WSS-M4D578-B1 is based on virgin materials. 3.4.3 WRS-M4D578-B2 must c

17、ontain minimum 65% (Post-Consumer Recycled (PCR) and/or Post Industrial Recycled (PIR) content by weight and Renewable Bio-Based, as defined by WRS-M99P42-A1 and WNS-M99P42-A4).
