APPLICATIONThese specifications were originally released for materials used forcle aning operations for metallic basecoats S-M32J110-B, solid colortopcoats SK-M98J9552-A and clearcoats SK-M32J9553-A.3. REQUIREM
3、ENTS3.1 STATISTICAL 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 i
4、n the final product is continuously reduced.3.2 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 thermograms established for i nitial approval shallcon
5、st 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.3.3 COMPOSITIONSK-M14J9561-A: Blend of aromatic hydrocarbons, g lycoleth

Dipphosphated test panels (UMA 18005) into the dilu ted enamel ina vertical position and dry for 24 hours at roo
10、m temperature20 +/- 3 C, also in a vertical position.Tes t: Fill thinners SK-M14J9556-A, S-M14J245-A and thethinner under test into beakers. Dip one prepar ed test panelinto each beaker so that half of it is dipped into thethinner. Leave it there without stirring until the enamel iscompletely dissol
11、ved.Evaluation: The time to dissolve the enamel in the thinnerunder test shall be same as or less than the time todissolving in the comparable thinner.ENGINEERING MATERIAL SPECIFICATIONSK-M14J9561-A/B/C/DWP 3948-b Page 3 of 4 3.4.6 Specific Resistance S ee initial sampleTo be agreed with Manufacturi
