GENERAL.

This document covers the requirements for conducting nondestructive tests (NDT) used in determining the presence of surface and internal discontinuities in metals. It also contains the minimum requirements necessary to qualify NDT personnel, procedures, and equipment. This document does not contain acceptance criteria for NDT. This document does not cover all of the requirements for performing NDT in an underwater environment. Nondestructive tests in an underwater environment shall be performed as specified in NAVSEA S0600-AA-PRO-070.

Inspection Areas.

Areas to be inspected shall be specified in the applicable drawings, specifications, contracts, or purchase orders. Drawings specifying NDT shall employ symbols in accordance with AWS A2.4.
