    1、Designation: F2325 03 (Reapproved 2009)Standard Classification forMulti-Layer Steel (MLS) and Other Metal Layer Gaskets forTransportation Applications1This standard is issued under the fixed designation F2325; the number immediately following the designation indicates the year oforiginal adoption or

    2、, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This classification covers a means for specifying Multi-Layer Steel (MLS) and o

    3、ther Metal Layer Gaskets for Trans-portation Applications by application and construction. Thesestructures are composed of one or more steel or metal layers ofmaterial, which may have coatings or embossments. Commer-cial materials designated as composite or enveloped gaskets areexcluded from this cl

    4、assification and are covered by Classifi-cation F868 and Practice F336, respectively.1.2 Since all of the properties that contribute to gasketperformance are not included, use of this classification as abasis for selecting an MLS or Metal Layer gasket is limited.1.3 This standard does not purport to

    5、 address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory requirements prior to use.2.

Embossmentsmay also

Significance and Use4.1 This classification is intended to encourage uniformityin reporting properties of MLS and Metal Layer gaskets, toprovide a common language for comm

    11、unications betweenproducers and users, and to guide engineers and designers inthe application and construction of commercially availablegaskets.5. Basis of Classification5.1 This classification is based on the principle that MLSand Metal Layer gaskets should be described, in terms of thetransportati

    12、on application and construction. Thus, users ofMLS and Metal Layer gaskets can, by selecting differentcombinations, define various parts needed for specific applica-tions. Likewise, producers can report applications and con-struction of available products.1This classification is under the jurisdicti
