NDT codes & standards reference — standards across six issuing bodies

Plain-language summaries of the inspection codes and NDE standards Atlantis NDT uses on a daily basis: ASME Section V articles and B31.3 process piping; API in-service inspection codes (510, 570, 653) and supporting RPs (571, 579, 580, 581, 1104); ASTM PT/MT/RT general practices; ISO equivalents (3452, 9712, 9934, 17636, 17640); AWS D1.1/D1.5 welding codes; EN 12668 UT equipment; and the NACE MR0175/SP0490 sour-service and pipeline coating standards. Each entry summarizes scope, key requirements with clause references, revisions history, and the certifications and methods to which it applies.

About this standards library

The codes and standards that govern NDT examinations and the in-service inspection decisions built on them — what each covers, its key requirements, which certifications reference it, and how it is applied in a working inspection programme. Examination standards define how a method is performed; construction and in-service codes define what is acceptable. Both are needed to make a disposition defensible.

Where to go next

If you are qualifying people, start with NDT training and certification and the ASNT certification pathways. If you are building or defending a programme, start with ASNT Level III consulting. If the problem is that the records exist but cannot be produced on demand, that is what inspection management software and the asset integrity platform are for. Ask a Level III directly.
