Scope

1.1 This classification system² provides a means for specifying or describing pertinent properties of commercial nonmetallic gasket materials. Materials composed of asbestos, cork, cellulose, and other organic or inorganic materials in combination with various binders or impregnants are included. Materials normally classified as rubber compounds are not included, since they are covered in Classification D 2000. Gasket coatings are not covered, since details thereof are intended to be given on engineering drawings or in separate specifications. While the facing materials for laminate composite gasket materials (LCGM) are included in Classification System F 104, materials normally classified as LCGM are not covered since they are included in Classification F 868.

1.2 Since all of the properties that contribute to gasket performance are not included, use of the classification system as a basis for selecting materials is limited.

1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
