2、 INTERIOR 1. SCOPE The material defined by this specification is a thermoplastic injection molding compound based on polypropylene 30% coupled glass fiber reinforced for interior molded in color applications. 2. APPLICATION This specification is released for material used for a glovebox latch paddle

3、 on the C489 program. 2.1 LIMITATIONS This material has low impact resistance at low temperatures. Production level materials must be used in preparing test parts / panels. The use of improper sample preparation materials can influence test results. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PROD

4、UCTION MATERIALS Material suppliers 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 va

5、lues 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 to meet specification limits. 3.1.2 WSS-M4D732-B4 is based on virgin materials. Materials with post-consumer, p

6、ost industrial, or repolymerised recycled materials as defined by WRS-M99P42-A1 are preferred and should be used whenever feasible. 3.1.3 The use of regrind is permitted, for economic / environmental reasons, with compliance as indicated in Ford Engineering CAD and Drafting Standard E-4. 3.1.4 Mater

7、ials used in interior applications must meet the requirements outlined in WSS-M99P2222-D1/Latest, Performance, Vehicle Interior Environment Quality Material/Component Requirements. Data must be included in material submission package 3.15 Performance Criteria: Parts using this specification shall me

8、et the appropriate performance specifications, WSS-M15P4-F/ Latest for Hard, Interior Molded-in-Color component performance. 3.2 SAMPLE PREPARATION Unless otherwise specified all tests shall be carried out on injection molded, one-end gated test ENGINEERING MATERIAL SPECIFICATION WSS-M4D732-B4 Copyr
