5、3 This specification was released originally for material used for non-visible applications (exterior and underhood/underbody) and containing post consumer or post industrial recycled resin content. 2.1 LIMITATIONS This material absorbs and retains moisture. Part design and tolerances must accommoda

6、te changes in part dimensions and physical properties due to moisture absorption or loss in the service/assembly environment. This material is not suitable for long term exposure to engine coolant, or direct exposure to strong acids or bases. For B1 and B3: This material typically does not contain U

7、V stabilizers, long term exposure to direct sunlight will cause chalking and loss of gloss without suitable additives. For B3 only: This material has low impact resistance. 3.

13、ere 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 content exceeds 0.2%, condition the material for a minimum of

14、 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.

15、ectra 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 specification shall produce IR spectra and thermograms that corres

16、pond 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 indicated that the mean and +/- 3 sigma values were to be reported. Th

17、e 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-M4D648-B1 and WSS-M4D648-B2 are based on virgin materials. 3.4.3 WRS -M4D648-B3 must contain 100% (Post Consumer Recycled (PCR)

18、and/or Post Industrial Recycled (PIR) content and Renewable Bio-Based, as defined by WRS-M99P42-A1 and WNS-M99P42-A4). Actual percent to be reported as part of the data submission pack.
