Meaning and use
3.1 As the pipe coating is subject to concentrated pressure exerted by the weight of the pipe and the backfill, the test is primarily used to determine the resistance of the coating to penetration or deformation under controlled conditions.

3.1.1 If the coating is not penetrated, the deformation of the compressible coating does not indicate a potential defect in the burial service. Deformation is not comparable to penetration of coating.

ASTM G17-07-2020 Standard Test Method for Penetration Resistance of Pipe Coatings (Blunt Rods)

range
1.1 This accelerated test method is used to determine the relative resistance of steel pipe coatings to penetration or deformation of blunt rods under specified loads. This test method is suitable for the test of all kinds of nonmetallic pipe coatings under various temperatures.

1.2 The value expressed in SI units with three significant decimals shall prevail. The values given in parentheses are for reference only.

1.3 This standard is not intended to address all, if any, safety concerns associated with its use. It is the responsibility of users of this standard to establish appropriate safety, health and environmental practices and to determine the applicability of regulatory restrictions prior to use.

1.4 This international standard is based on internationally recognized standardization principles established in the Decision on International Standards, Guidelines and Recommended Principles issued by the WTO Technical Barriers to Trade (TBT) Committee.
