9、l 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 coating with seal base material (s) is the responsibility of the Tier One supplier. T

10、he Tier One supplier shall have the seal tested against the applicable performance specification requirements, and must keep all tested samples for review by Ford Materials Engineering. Table 3.0 describes the construction of the dynamic seal, and must be submitted with Supplement A. (Reference Supp

11、lement A). The Tier One supplier is responsible for including Table 3.0 and this performance specification on the part drawing. 3.3 FINISHED PARTS Testing must be conducted at Design Verification (DV) and Product Validation (PV) per Table 2.0 (including Supplement A), unless otherwise agreed to by M

12、aterials Engineering, and on actual production parts or a section of the part whenever possible. Where part dimensions limit testing equipment access, representative test samples may be substituted. DV Testing must follow the Process Window DOE, paragraph 3.5. PV Testing must be conducted on actual

13、production processed parts. No change in material, facility, or processing is permitted without written approval from Ford Materials Engineering Activity, via SREA. All test values are based on parts conditioned in a controlled atmosphere of 23 +/- 2 C and 50% R.H. for not less than 24 h prior to te

14、sting and tested under the same conditions unless otherwise specified. 3.4 APPEARANCE: COLOR, FINISH, SURFACE (FLTM BI 109-01) The part shall be generic black (GAXA) in color and have, at most, a “K“ level (2-4 on a 60 gloss meter) for gloss, unless otherwise specified on the engineering drawing or

15、PDL. The color shall be uniform (no change in color less than Rating 5 of the Gray Scale, AATCC Evaluation Procedure 1/ISO 105-A02) along the entire length of the seal assembly, including molded or mitered corners and splices. The surface shall be free of blisters, voids and any bloom unless otherwi

16、se specified on the engineering drawing. 3.5 PROCESS WINDOW DEFINITION The supplier shall perform a DOE for development of new materials and for continuous improvement of current materials, utilizing response surface analysis to determine the Process Window of the system. The variables to be include

17、d in the design are cure temperature (material and coating), conveyor speed, and coating flow. An initial screening experiment should be run to determine what level will generate a window which includes testing to failure. This screening experiment should be reviewed with the Materials Engineer to s

18、et up the final DOE. Response attributes to the DOE should be based on the materials tested and should include, but not be limited to: ENGINEERING MATERIAL SPECIFICATION WSS-M9P9-C Controlled document at www.MATS Copyright 2014, Ford Global Technologies, LLC Page 3 of 14 Coefficient of Friction Film
