SCOPE The material defined by this specification is a low modulus, high elongation fluoroelastomer, with excellent oil and heat resistance, suitable for long-term, high t

3、emperature service conditions. 2. APPLICATION This specification was released originally for material used in the “best-in-class“ gasket for the rocker arm and oil pan, where high flange temperature resistance is required. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material s

4、uppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.4 MATERIAL TESTING 3.4.1 Preparation of Test Specimens All tests shall be performed on specimens die-cut from the molded parts or from molded ASTM test sheets, press cured for

5、10 minutes at 177 C and post cured for 16 h at 232 C. The ASTM test sheets shall have the following dimensions: 150 x 150 mm, min x 2.0 +/- 0.2 mm. Specimens taken from parts shall be cut as follows: . Tensile Strength according to ASTM D 412, die C, full thickness. If the length between the compres

6、sion limiters is not sufficient to accommodate die C, use a die exactly one-half the dimensions of the die C. . Tear Strength according to ASTM D 624, die B, 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
