意味と使い方
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.
