2、, CELLULOSE/SYNTHETIC RUBBER AND RESIN ESE-M8G164-A NOT TO BE USED FOR NEW DESIGN 1. SCOPE: The material defined by this specification is a moderate temperature heat insulating material composed of cellulose fibers, synthetic rubber and resins. This material is asbestos free. 2. APPLICATION: This sp

3、ecification was released originally for material used as a spacer gasket between the carburetor and intake manifold when the temperature will not exceed 150 C. 3. REQUIREMENTS: All tests shall be conducted in accordance with ASTM F 104, Type 3 material or SAE J 90 unless otherwise specified. Test sp

4、ecimens are to be selected from finished gaskets when practicable. Specimens used for fluid properties should not be cut or trimmed prior to exposure. 3.1 CONSTRUCTION The spacer-gasket consists of a cellulose board reinforced with an SBR rubber or NBR/phenolic resin binder, coated on all the outer

5、edges and sides with nitrile rubber and with all the bolt holes reinforced with phenolic bushing. The gasket is also coated with a release agent. 3.2 DENSITY, min 720 - 832 kg/m3 (Type 2) 3.3 COMPRESSIBILITY 8 - 20% (ASTM F 36, 34.5 MPa load) Recovery, min 50% 3.4 TENSILE STRENGTH, min 10.3 MPa 3.5

8、sticking and tearing with no evidence of corrosion . Metal Plates . Aluminum to Aluminum . Aluminum to Steel . Steel to Steel Test Method: A 15.9 mm I.D. x 38.1 mm O.D. test specimen is clamped between 2 discs of 13.5 mm I.D. x 51 mm O.D. metal plates (maximum thickness 1.57 mm) backed by 12.7 mm st

9、eel plates. 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 149 +/- 3 C for 5 h. Remove and allow to cool to room temperature. The specimen shall come off the metal plates with a minimum of tearing and the metal plates must show

10、 no evidence of corrosion. 3.8 PHENOLIC BUSHINGS 3.8.1 Compressive Strength, min 69 MPa (ASTM D 695) 3.8.2 Deflection at 69 MPa, max 10% (ASTM D 695) 3.8.3 Removal Force From Gasket, min 378 N 3.8.4 Density, min 1394 kg/m3 (ASTM D 792) 3.9 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS Ford Moto
