APPLICATION This specification was released originally for materials used for underbody shields, wheel liners, and/or other non visible applications and containing post consumer or post industrial recycled resin content 2.1 LIMITATIONS This material does not co

4、ntain UV stabilizers, therefore long term exposure to direct sunlight could cause chalking and loss of gloss, and must not be used for visible (mold-in-color or painted) applications. These materials should not be used for interior applications and have not been tested to meet Vehicle Interior Envir

5、onment Quality Material/component Performance Requirements (WSS-M99P2222-D1). 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,

6、 CAD file, or other documents. The list of approved sources is located within Ford at or available externally through a Ford Materials Engineer. 3.2 CONDITIONING AND TEST CONDITIONS All test values are based on material conditioned for not less than 24 h prior to testing in a controlled environment

7、 of 23 +/- 2 C and 50 +/- 5% relative humidity. Testing of the material should occur in the conditioning environment or soon after removal. 3.3 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS 3.3.1 Many 4D resin specifications prior to 2011, identified certain requirements with the symbol (s), which

8、indicated 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. 3.3.2 The use of regrind is permitted, for economic / environmental

9、reasons. Part manufacturers ENGINEERING MATERIAL SPECIFICATION WRS-M4D952-A4 Copyright 2016, Ford Global Technologies, LLC Page 2 of 7 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 engi

10、neering 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). 3.3.3 This material must contain a minimum of 75% Post Consumer Recycled (PCR) and/or Post
