    Withdrawn Rationale:

    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 %.

    Formerly under the jurisdiction of Committee D01 on Paint and Related Coatings, Materials, and Applications, this test method was withdrawn in June 2013. This standard is being withdrawn without replacement because: (1) limited/no use within industry, (2) no known labs to do the testing, and (3) other bendability tests exist and are used more commonly within the industry.

    1. 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.
