Aluminum to Steel. Steel to SteelTest Method: A 15.9 mm I.D. x 38.1 mm O.D. test specimen is clampedbetween 2 discs of

10、 13.5 mm I.D. x 51 mm O.D. metal plates (maximumthickness 1.57 mm) backed by 12.7 mm steel plates. A 12.7 mm steelbolt is inserted through the hole and a nut put on it. Tighten thebolt to 79 N.m. Heat the assembly to 149 +/- 3 C for 5 h. Removeand allow to cool to room temperature. The specimen shal

11、l come offthe m etal plates without tearing and the metal plates must show noevidence of corrosion.3.9 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSISFord Motor Company, at its option, may conduct infrared and/ortherma l analysis of material/parts supplied to this specification.The IR spectra and

12、 thermograms established for i nitial approval shallconst itute the reference standard and shall be kept on file at thedesignated material laboratory. All samples sha ll produce IR spectraand thermograms that correspond to the reference standard when testedunder the same conditions.3.10 STATISTICAL

13、PROCESSSupplie rs must conform to the requirements of Ford Quality SystemStand ard Q-101. A mutually acceptable Control Plan as describedtherein is required for material/source approval. Appropriatestatist ical tools must be used to analyze process/product data sothat variation in the final product
