2、SCOPEThe mate rial defined by this specification is a high grade, multipurposega sketing material comprised of non-asbestos reinforcing compounds incombination with a fully cured nitrile rubber.2. APPLICATIONThi s specification was originally released for materials requiring goodautoma tic transmiss

3、ion fluid, and good dimensional stability. Thesemate rials exhibit superior crush resistance under high flange loading.Typical gasket applications include extension housing to case.3. REQUIREMENTS3.1 STATISTICAL PROCESSSupplie rs must conform to the requirements of Ford Quality SystemStand ard Q-101

4、. 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 is continuously reduced.3.2 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSISFord Motor

5、 Company, at its option, may conduct infrared and/ortherma l analysis of material/parts supplied to this specification.The IR spectra and thermograms established for i nitial approval shallconst itute the reference standard and shall be kept on file at thedesignated material laboratory. All samples

6、sha ll produce IR spectraand thermograms that correspond to the reference standard when testedunder the same conditions.3.3 CONDITIONING AND TEST CONDITIONSAll tests shall be conducted in accordance with ASTM F 104, Type 7materia l unless otherwise specified. The requirements of thisspecifi cation a

7、re valid for gasket material of 0.4 to 1.2 mmthickness. Test specimens are to be selected from finished gasketswhen practicable.Prior to testing the ma terial shall be conditioned in an oven at 100+/- 2 C for 1 h and allowed to cool to 23 +/- 2 C in a desiccatorcontaining anhydrous calcium chloride.
