Bedeutung und Verwendung
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 Standardtestmethode für den Durchdringungswiderstand von Rohrbeschichtungen (Stumpfe Stäbe)

Reichweite
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. Die in Klammern angegebenen Werte dienen nur als Referenz.
