ASME Section V comprises Subsection A, Subsection B, and mandatory and non- mandatory appendixes. Subsection A delineates the methods of nondestructive examination, and Subsection B contains various ASTM standards covering nondestructive examination methods that have been adopted as standards. The standards contained in Subsection B are for information only and are non-mandatory unless specifically referenced in whole or in part in Subsection A or referenced in other code sections and other codes, such as ASME B31, Pressure Piping Code.
The nondestructive examination requirements and methods included in ASME Section V are mandatory to the extent they are invoked by other codes and standards or by the purchaser’s specifications. For example, ASME Section III requires radio- graphic examination of some welds to be performed in accordance with Article 2 of ASME Section V.
ASME Section V does not contain acceptance standards for the nondestructive examination methods covered in Subsection A. The acceptance criteria or standards shall be those contained in the referencing code or standard.
