Standard Classification for Laminated Composite Gasket Materials
N F868
Annotation
This classification covers a means for specifying or describing pertinent properties of commercial laminate composite gasket materials (LCGM). These structures are composed of two or more chemically different layers of material. These materials may be organic or inorganic, or combinations with various binders or impregnants. Gasket coatings are not covered since details thereof are intended to be given on engineering drawings, or as separate specifications. Commercial materials designated as enveloped gaskets are excluded from this classification; they are covered in Practice F 336.
Since all of the properties that contribute to gasket performance are not included, use of this classification as a basis for selecting LCGM is limited.
The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.

Стандартная классификация для слоистых сложных прокладочных материалов
Эта классификация покрывает средние значения для определения или описания подходящих свойств коммерческих прокладочных материалов соединения ламината (LCGM). Эти структуры составлены из двух или больше химически различных уровней материала. Эти материалы могут быть органическими или неорганическими, или комбинации с различными переплетами или impregnants. Покрытия прокладки не покрыты, так как детали этого предназначены, чтобы быть данными на технических рисунках, или как отдельные спецификации. Коммерческие материалы, определяемые как окутанные прокладки, исключены из этой классификации; они покрыты на практике F 336.
