5、pot decor effects. 2. APPLICATION These specifications were released originally for materials used for various interior applications such as pillar trims, door bins, package tray side supports etc. 2.1 LIMITATIONS Mold-in-color part using this material must comply with all the requirements of WSS-M1

6、5P4-Latest. Production level materials must be used in preparing test parts / panels. The use of improper sample prep materials can influence test results. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard R

7、equirements. For Production Materials (WSS-M99P1111-A). 3.1.1 All requirements of this specification, identified by symbol(s), shall be met with data representing 3 sigma values using latest ISO test methods. 3.1.2 This specification is based on virgin materials, however materials with recycled cont

8、ent as defined by WSS-M99P42-A (post-consumer and/or post industrial recyclates and repolymerised recycled materials) should be used whenever technically feasible and following all materials and PV testing required by Ford Materials Engineering. The use of regrind is permitted, for economic / enviro

9、nmental reasons, with compliance as indicated in WSS-M99P1111-A.

10、l 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 time of initial approval. Annually the supplier will review the in

11、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 submitted data may result in deletion from the Ford Approved Source List.
