2、EEL, EPOXY RESIN COATED ESE-M8G231-A3 1. SCOPE The material defined by this specification is a steel laminated gasket which consists of three layers of steel. The block side plate and the cylinder head side plate are coated with a hi gh temperature resistant NBR elastomer on the outside. The middle

3、plate is coated with a high temperature resistant NBR on both sides. 2. APPLICATION This specification was released originally for material requiring exceptional compressive strength as w ell as excellent sealing at high temperatures as required by cylinder head gaskets. 3. REQUIREMENTS Material spe

4、cification requirements are to be used for initial qualification of materials 3.1 QUALITY SYSTEM REQUIREMENTS Material suppliers and part p roducers must conform to the Companys Quality System Requirements. 3.2 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS IR spectra and thermograms established

5、 for initial approval shall constitute the reference standard and shall be kept on file at t he designated material laboratory. All samples shall produce IR spectra and thermograms that correspond to the reference standard when tested under the same conditions. 3.3 CONSTRUCTION The gasket consists o

6、f three steel plates coated after assembly wit h an NBR elastomer. The center plate of the gasket is coated on both sides before assembly with a micro thin layer of rubber. 3.4 BLOCK SIDE PLATE 3.4.1 Metal 1008/1010 (SAE J403) ENGINEERING MATERIAL SPECIFICATION ESE-M8G231-A3 Page 2 of 3 Copyright 20
