3.1 Since pipeline coatings are subjected to concentrated pressures exerted by the weight of the pipe and the backfill, this test is intended primarily for determining the resistance of the coating to penetration or deformation under controlled conditions.

3.1.1 Deformation of a compressible coating does not signify a potential weakness in underground burial service, if the coating is not penetrated. Deformation cannot be compared to penetration into and through a coating.
