ComST Date of publication: The minimum number of specimens and the tests to which they shall be subjected shall be as given in with Table 5. Where installation methods involve plastic deformation of the pipe, the specimen shall break outside of the weld and fusion zone to be deemed acceptable. NOTE In order to overcome the effect of pressure fluctuations between the bore of the pipe and the habitat it is common practice to leave part of the root incomplete whilst further weld passes are deposited. The method for testing full penetration repair and re-repair welds shall be in accordance with 8.
