SCOPEThi s specification defines the bond requi
2、rements for pressure sensitiveadhesive coated sponge rubber.2. APPLICATIONThi s specification was released originally for assemblies consisting ofpressure sensitive, closed cell sponge rubber, bonded to chromium platedsub strates. The pressure sensitive adhesive is intended as an assemblyaid. Con se
3、quently, it should be used only where the sponge rubber ismechanically retained in final assembly.3. REQUIREMENTS3.1 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/s
4、ource approval. Appropriatestatist ical tools must be used to analyze process/product data sothat variation in the final product is continuously reduced.3.2 CONDITIONING AND TEST CONDITIONSAll test values indicated herein are based on ma terial conditioned ina control led atmosphere of 23 +/- 2 C an
