Kahulugan at Gamit

3.1 Since the pipe coating is subject to concentrated pressure exerted by the weight of the pipe and the backfill, this test is mainly 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 underground burial service. Deformation is not comparable to penetration coating.

Saklaw

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 applicable to the test of all kinds of non-metallic pipe coatings under various temperatures.

1.2 The value of three significant decimal places in SI units shall prevail. Ang mga halaga na ibinigay sa mga panaklong ay para sa sanggunian lamang.

1.3 Ang pamantayang ito ay hindi nilayon upang matugunan ang lahat ng mga isyu sa kaligtasan, kung meron man, na nauugnay sa paggamit nito. Responsibilidad ng mga gumagamit ng pamantayang ito na magtatag ng angkop na kaligtasan, health, and environmental practices and to determine the applicability of regulatory restrictions prior to use.
