SCOPE The materials defined by these specifications consist of a low carbon steel core covered equally on both sides with a compressed graphite sheet. 2. APPLICATION These s pecifications were re
3、leased originally for material used where high temperature resistance is paramount, such as a gasket for the EGR valve and carburetor spacer. 3. REQUIREMENTS 3.1 CONSTRUCTION 3.1.1 Steel Core Low carbon steel. Thickness: ESE - M8 G169 - A ESE - M8G169 - A2 0.0914 to 0.1509 to 0.1118 mm 0.1844 mm 3.1
4、.2 Graphite The compressed graphite sheet shall be plied uniformly and bonded to each side of the steel core to meet requirements of the application at the thickness specified on the e ngineering drawing. 3.2 FINISHED GASKET All tests shall be conducted in accordance with ASTM F 104, Type 5 material
5、s, unless otherwise specified. 3.2.1 Immersion in Liquids Distilled Water 22 h at boiling Permanent Antifreeze 48 h at boili ng After immersion in above fluids, as specified, the graphite shall be firm and must not separate from the steel core.

10、standard and shall be kept on file at the designated material laboratory. All samples shall produce IR spectra and thermograms that correspond to the reference standard when tested under the same conditions. 3.4 REQUIREMENTS Material s pecification requirements are to be used for initial qualificati
11、on of materials. 3.4.1 Quality System Requirements Material suppliers and part producers must conform to the Companys Quality System Requirements. 3.5 SUPPLIERS RESPONSIBILITY All mat erials supplied to this specification must be equivalent in all characteristics to the material upon which approval
12、was originally granted. Prior to making any changes to the material originally approved under this specification, whether or not such chang es affect the materials ability to meet the specification requirements, the Supplier shall notify the affected Purchasing, and Materials Engineering activities
13、(with reasons) of the proposed changes. Upon notification of the Company, further instructions will be provided. Note: Suppliers should be prepared to provide test data and samples demonstrating compliance to this specification, if requested. Substance restrictions imposed by regulations or Company
14、direction applies to the materials addressed b y this document. The restrictions are identified in Restricted Substance Management Standard WSS - M99P9999 - A1. 4. APPROVAL OF MATERIALS Materials defined by this specification for direct supply to the Company must have prior approval. Certain materia
15、ls subcontracted by part suppliers may also require prior approval. These include materials critical to the Companys business for regulatory, safety, environmental or compatibility requirements or contractual agreements. Suppliers desiring approval of thei r materials shall first obtain an expressio
16、n of interest from Purchasing, Design or Materials Engineering activity. Upon request, the Supplier shall submit a completed copy of their laboratory test reports, signed by a qualified and authorized representat ive of the test facility, demonstrating full compliance with all the requirements of this specification.
