APPLICATIONThi s specification was released originally for adhesives used to bondglass, plastic, stainless steel, and phosphated galvanized steel.Compl iance wit
3、h this performance specification does not guarantee theadhesiv e will function for all potential applications on a vehicle. Thespe cific assembly should be evaluated to design engineering performancerequirements.3. REQUIREMENTS3.1 STATISTICAL PROCESSSupplie rs must conform to the requirements of For
4、d 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 AN
5、D/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 ma
6、terial 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 materials conditionedin a co ntrolled atmosphere of 23 +/- 2 C and
7、50 +/- 5 % relativehumidity for not less than 24 h prior to testing and tested under thesame conditions unless otherwise specified.ENGINEERING MATERIAL SPECIFICATIONWSB-M11P41-B1WP 3948-b Page 2 of 4 3.4 SHEAR ADHESION, min(SAE J1523, 0.76 mm bondline thickness, 25 mm bondoverlap, 50 mm/minute pull
