SCOPEThe material define
2、d by this specification is a solvent release liquidgasket based on chlorosulfonated polyethylene.2. APPLICATIONThis material was originally released for sealing lever to transmissiongear shaft of 5 speed rear wheel drive.3. REQUIREMENTS3.1 STATISTICAL PROCESSSuppliers must conform to the requirement
3、s of Ford Quality SystemStandard Q-101. A mutually acceptable Control Plan as describedtherein is required for material/source approval. Appropriatestatistical tools must be used to analyze process/product data sothat variation in the final product is continuously reduced.3.2 INFRARED SPECTROPHOTOME
4、TRY AND/OR THERMAL ANALYSISFord Motor Company, at its option, may conduct infrared and/orthermal analysis of material/parts supplied to this specification.The IR spectra and thermograms established for initial approval shallconstitute the reference standard and shall be kept on file at thedesignated
5、 material laboratory. All samples shall product IR spectraand thermograms that correspond to the reference standard when testedunder the same conditions.3.3 CONDITIONING AND TEST CONDITIONSAll test values indicated herein are based on material conditioned ina controlled atmosphere of 23 +/- 2 C and
