API 510 Repair, Alteration, Re-Rating (Section 8)
Clifford Matthews · ASME Press eBooks · 2010
API codes are not only about inspection. Since their inception in the 1950s, the in-service inspection codes API 510, 570 and 653 have had the activities of repair, alteration and re-rating as a central part of their content. Worldwide, other in-service inspection codes do not necessarily follow this approach — re-rating, in particular, is uncommon in some countries. Many countries, as a result of legislation, experience or simple technical preference, do not do it at all. Remember, however, that the API 510 exam is strictly about what is in the code documents, not your experience or personal view, so you need to accept the API philosophy as set out in the codes.
