10、 Development Materials Activity. 3.1.2 This specification is based on virgin materials, however materials with recycled content 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
11、 all materials and PV testing required by Ford Materials Engineering. The use of regrind is permitted, for economic / environmental reasons, with compliance as indicated in WSS-M99P1111-A. Critical Process Parameters At the request of Ford Materials Engineering the supplier shall be responsible to c
12、ollect 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 process data with For
13、d Materials Engineering to show that the process has remained under control. The data needs to be submitted in January for the previous calendar year.
