SCOPE The materials defined by these specifications are magnetizable and heat bondable deadener sheetings with an anti-blo
5、cking surface finish on one side. WSK-M99G140-C1 and WSK-M99G140-C3 consist of single layered, WSK-M99G140-C2 and WSK-M99G140-C4/C5/C6/C7 of double layered deadener sheetings, of which one layer is magnetizable. 2. APPLICATION Material specification requirements are to be used for initial qualificat
6、ion of materials. These specifications were released originally for materials used as vibration deadeners in the passenger compartment to the inner sides of roof, door tail gate and side wall. WSK-M99G140-C1/C2 are applied in inverted, WSK-M99G140-C3/C4/C5 in vertical or horizontal position. WSK-M99
7、G140-C6/C7 are molded parts. Prior to use the material must be magnetized under actual production conditions. It is applied to baked electrocoat. 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production
