SCOPE The materials defined by this specification are low modulus, high elongation silicone rubber with

3、 low silicone volatiles, excellent tear resistance and compression set, suitable for long-term, high temperature service conditions. 2. APPLICATION This specification was released originally for materials used as the best-in-class gaskets for the rocker arm cover and oil pan where a low volatile sil

4、icone rubber is needed to prevent silica contamination of emission components. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.4 MATERIAL TESTING 3.4.

5、1 Preparation of Test Specimens Test specimens may be taken from either test sheets or molded parts. To insure a proper cutting of specimens, backup all test sheets/parts with cardboard or a rubber sheet. The test sheets shall have the following dimensions: 150 x 150 mm, min x 2.0 +/- 0.2 mm. The te

6、st sheets must be cured for 10 minutes at 177 C. Part specimens must be cut as follows: . Tensile Strength per ISO 371/ASTM D 412, die C, full thickness. If the length between the compression limiters is not long enough to accommodate a die C, use a die exactly one-half the dimensions of the die C.

7、. Tear Strength per ISO 34/ASTM D 624, full thickness. . Volume Change - 25 mm x part width x part thickness. . Compression Set - 25 mm long x part width x single thickness minus any skirt. Do not buff any sample including those with a bead, except for compression set. ENGINEERING MATERIAL SPECIFICA
