ASTM G70-07
Withdrawn Standard: Standard Test Method for Ring Bendability of Pipeline Coatings (Squeeze Test) (Withdrawn 2013)
ASTM G70
Scope
1.1 This method covers testing the relative resistance of pipeline coatings to cracking and spalling from deformation of the pipe by observing the effects of diametral compression of ring samples. The method is limited to thin film coatings having an elongation not exceeding 5.0 %.
1.2 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.
