SCOPE The materials defined by these specifications consist of cellulose fibers bonded with synthetic rubber and

    4、coated with a film of nitrile rubber. The rubber is added to the base material to compensate for very small defects in the flange surfaces such as nicks and scratches. The coating must be unbroken and continuous. 2. APPLICATION These specifications were released originally for materials used in gask

    5、ets to seal coolants, oils and fuels where low, medium, and high flange loads are encountered. ESE-M8G173-A1: Is a high tensile, high density, low compressing, good recovery material where heavy duty flange application with high bolt pressures and good torque retention is needed. An anti-stick coati

    6、ng is added to the gasket to prevent blocking. ESE-M8G173-A2: Is an all purpose, gasket that seals most fluids at medium bolt pressure with good torque retention. An anti-stick coating is added to the gasket to prevent blocking. ESE-M8G173-A3: Provides good sealing with light and irregular flanges u

    7、nder minimal loading. Fair torque retention. An anti-stick coating is added to the gasket to prevent blocking. ESE-M8G173-A5: Is an all purpose gasket that seals most fluids at medium bolt pressure with good torque retention. Gasket contains no anti-stick. 3. REQUIREMENTS Material specification requ

    8、irements are to be used for initial qualification of materials. All tests shall be conducted in accordance with ASTM F 104 Type 3 material unless otherwise specified. Test specimens are to be selected from finished gaskets when practicable. Properties of very thick or very thin gaskets may vary slig

A 12.7 mm steel bolt is inserted through the hole and a nut put on it. Tighten the bolt to 79 N.m. Heat the assembly to 121 +/- 3 C for 5 h. Remove and allow to cool to room temperature. The specimen shall come off the metal plates without tearing and the metal plates must show no evidence of corrosion.
