9、onmental 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 collect critical process control data on each lot of material produced. Testing required will be jointly developed between F

10、ord 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 Ford Materials Engineering to show that the process has remained under control. The data needs to be submitted in January for

11、the previous calendar year.
