SCOPEThe mate rials defined by these specifications are glass cloth tapes withthermosetting, pressure sensitive adhesive.ESF-M3G156-A is ra
3、ted for continuous separation at 155 C.ESF-M3G156-A2 is rated for continuous operation at 200 C.2. APPLICATIONThese s pecifications were released originally for materials used in theignition coil and alternator.3. REQUIREMENTS3.1 STATISTICAL PROCESSSupplie rs must conform to the requirements of Ford
4、 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 is continuously reduced.3.2 INFRARED SPECTROPHOTOMETRY AND
5、/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 thermograms established for i nitial approval shallconst itute the reference standard and shall be kept on file at thedesignated mat
6、erial laboratory. All samples sha ll produce 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 ma terial conditioned ina control led atmosphere of 23 +/- 2 C and 5
