SCOPEThe mat erials defined by this specification are slow solvents with a lowevaporation rate.2.
2、 APPLICATIONThis specification was originally released for materials used as controladditi ves for levelling and flash off properties of solvent borne primer/surfaces.3. REQUIREMENTS3.1 STATISTICAL PROCESSSupplie rs must conform to the requirements of Ford Quality SystemStand ard Q-101. A mutually a
3、cceptable 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 Company, at i
4、ts 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 sha ll produce
