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

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

The curves established for initial approval shall constitute the reference standard and shall be kept on file at Central Laboratory. All samples shall produce curves that correspo
12、nd to the reference standard when tested under the same conditions as those specified on the master curve. ENGINEERING MATERIAL SPECIFICATION ESE-M8G164-A Page 3 of 3 3.10 SUPPLIERS RESPONSIBILITY Material supplied to this specification must be equivalent to that originally approved. Changes in form
13、ulation or processing shall not be made without prior approval as described in Supplier Procedure I-A. 4. APPROVAL OF SUPPLIERS: Suppliers to this specification must be approved by the affected product engineering office. Procedure for gaining approval of a specific material to a new/existing ES-M specification is contained in Supplier Procedure I-A. Approved new suppliers will be added to the Engineering Materials Approved Source List.
