For thermoplastic materials, this specification is based on virgin material only. The use of regrind is permitted, for economic/environmental reasons, with
9、compliance as indicated in WSS-M99P1111-A. 3.2 DYNAMIC SEAL PERFORMANCE MANAGEMENT All seals evaluated under this performance specification must have Supplement A completed and signed by Ford Materials Engineering, the material/coatings supplier, and the Tier One supplier. Compatibility of the seal
10、coating with seal base material (s) is the responsibility of the Tier One supplier. The Tier One supplier shall have the seal tested against the applicable performance specification requirements. Table 3.0 describes the construction of the dynamic seal, and must be submitted with Supplement A. (Refe
