2、t 2012, Ford Global Technologies, Inc. GASKET, STEEL CORE-NON ASBESTOS FACING, LAMINATED WSE-M8G229-A NOT TO BE USED FOR NEW DESIGN 1. SCOPE The material defined by this specification is a non asbestos gasket facing material laminated on to a perforated low carbon steel core. 2. APPLICATION This spe

3、cification was released originally for material requiring high compressive strength and high temperature resistance such as exhaust manifold gasket(s). 3. REQUIREMENTS Material specification requirements are to be used for initial qualification of materials. Note: All tests shall be conducted in acc

4、ordance with ASTM F 104 Type 1 material unless otherwise specified. The requirements of this specification are valid for gasket material of 1.02 to 1.22 mm thickness. Test specimens are to be selected from finished gaskets when practicable. Prior to testing the materials shall be conditioned in an o

5、ven at 100 +/-2 C for 1 hour and allowed to cool to 21 to 30 C in a desiccator containing anhydrous calcium chloride. 3.1 QUALITY SYSTEM REQUIREMENTS Material suppliers and part producers must conform to the Companys Quality System Requirements. 3.2 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS

6、 IR spectra and thermograms established for initial approval shall constitute the reference 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.

7、3.3 CONSTRUCTION The composite material consists of a quality grade of graphited non-asbestos/binder material secured to one side of pierced, tin plated, low carbon steel.

17、tics to the material upon which approval was originally granted. Prior to making any changes to the material originally approved under this specification, whether or not such changes affect the materials ability to meet the specification requirements, the Supplier shall notify the affected Purchasin

18、g, and Materials Engineering activities (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 restric

19、tions imposed by regulations or Company direction applies to the materials addressed by 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 h

20、ave prior approval. Certain materials 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 their materia
