1.1 ScopeThis specification covers various types, classes, and grades of flexible graphite material in which valve media temperatures are limited to a maximum of 1050°F (966°C). Where this specification is invoked as ASTM F 2168, Sections 1-18 apply. Where this specification is invoked as ASTM/DoD F 2168, Sections 1-18 and the Supplementary Requirements are applicable.

1.2 The values stated in SI units are to be regarded as standard.


This specification covers various types, classes, and grades of flexible graphite material in which valve media temperatures are limited to a maximum temperature. The material shall be classified into two types, classes, and grades. Type I is a corrugated ribbon or textured tape, Type II is die-formed ring. Class 1 is for use where detrimental material content of the packing need not be controlled beyond normal manufacturing limit and Class 2 is for use where detrimental material content must be controlled to the limits specified herein. Grade A is treated with corrosion inhibitor and Grade B not treated with corrosion inhibitor. Different tests and measurements shall be conducted in order to determine the following properties: size, bulk density, ash content, and graphite purity.
