2、MPOUND, INTERIOR WSS-M4D960-A2 1. SCOPE The material defined by this specification is a molded in color molding compound based on acrylo-nitrile-butadiene-styrene (ABS) and PA6 blend that has been UV stabilized for unpainted interior applications. It has excellent chemical and stress crack resistanc
3、e, high impact strength and low gloss. 2. APPLICATION This specification was released originally for material used for door switch bezels on the Crown Victoria/Grand Marquis platform to replace painted PC/ABS. 2.1 LIMITATIONS This material absorbs and retains moisture. Part design and tolerances mus

7、th compliance as indicated in WSS-M99P1111-A. 3.1.3 WSS-M99P1111-A exception for conditioning of PA. DRY AS MOLDED: All test values indicated herein are based on material and specimens with moisture content not exceeding 0.2% except where noted (Moisture Conditioned) (test according to ISO 15512ASTM
8、 D 6869). All test materials have to be sealed in moisture-proof containers and stored at 23 +/-2 oC for at least 24 h immediately after processing. If the moisture content exceeds 0.2%, conditioning the material for a minimum of 16 h at 40 50 oC at a reduced pressure below 133 kPa. Conduct tests in
9、 a controlled atmosphere of 23 +/- 2 oC and 50 +/- 5% relative humidity. Individual specimens shall not be removed from closed containers until immediately before testing.

10、eters At the request of Ford Materials Engineering the supplier shall be responsible to collect critical process control data on each lot of material produced. Testing required will be jointly developed between Ford Materials Engineering and the supplier based on Control Plan and PFMEA review at the
11、 time of initial approval. Annually the supplier will review the in process data with Ford Materials Engineering to show that the process has remained under control. The data needs to be submitted in January for the previous calendar year. Data showing poor quality control measures or lack of submit
