ASTM F2168-13

Standard Specification for Packing Material, Graphitic, Corrugated Ribbon or Textured Tape, and Die-Formed Ring

ABSTRACT
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.
SCOPE
1.1 Scope—This specification covers various types, classes, and grades of flexible graphite material in which valve media temperatures are limited to a maximum of 966°C. Where this specification is invoked as ASTM F2168, Sections 1 – 18 apply. Where this specification is invoked as ASTM/DoD F2168, Sections 1 – 18 and the Supplementary Requirements apply.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
