2、N CONTENT, 25% RECYCLED MATERIAL BY WEIGHT 1. SCOPE The material defined by this specification is a 33% talc filled injection molding compound based on 25% recycled polypropylene homopolymer from post-consumer sources (PCR) and/or post industrial sources (PIR). 2. APPLICATION This specification was

3、released originally for material used for air-conditioning and heater housing. 2.1 LIMITATIONS This material does not contain UV stabilizers; long term exposure to direct sunlight will cause chalking and gloss loss. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material supplier

4、s and part producers must conform to the Companys Standard Requirements for Production Materials (WSS-M99P1111-A). 3.1.1 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. The spec

5、ification 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. 3.1.2 WRS-M4D939-A2 must contain 25% Post Consumer Recycled (PCR) and/ or post industrial sources (PIR) content as defined by WRS-M99P42-A1. The

6、 remaining portion of the material can come from virgin sources. 3.1.3 The use of 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 mus

7、t 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 Comany process (SREA). 3.1.4 Materials used in interior applications must meet the requi

8、rements outlined in WSS-M99P2222-D1/Latest, Performance,Vehicle Interior Environment Quality Material/Component Requirements. Data must be included in material submission package. 3.1.5 Performance Criteria: Parts using this specification shall meet the appropriate performance specification, WSS-M15
