ASTM C662-16

Standard Specification for Impervious Graphite Pipe and Threading

ABSTRACT
This specification covers standardization of pipe sizes and thread types used to join impervious graphite pipe and fittings. This specification may also be applied to impervious carbon pipe and fittings. Physical dimensions of impervious graphite and carbon pipes and threads shall be within the limits indicated in this specification.
SCOPE
1.1 This specification covers the standardization of the pipe sizes and types of threads used to join impervious graphite pipe and fittings. The thread standards may also be applied to impervious carbon pipe and fittings. It is limited to physical dimensions.

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.
