This document specifies the general principles for the application of the time-of-flight diffraction (TOFD) technique for both detection and sizing of discontinuities in low-alloyed carbon steel components.
This document also applies to other types of materials, provided the application of the TOFD technique is performed with necessary consideration of geometry, acoustical properties of the materials, and the test sensitivity.
Although this document is applicable, in general terms, for discontinuities in materials and applications covered by ISO16810, it contains references to the application on welds. This approach has been chosen for reasons of clarity as to the probe positions and directions of scanning.
Unless otherwise specified in the referencing documents, the minimum requirements specified in this document apply.
Unless explicitly stated otherwise, this document is applicable to the following categories of test objects as specified in ISO16811:
).
NOTE Techniques for the use of TOFD for weld testing are described in ISO10863 and the related acceptance criteria are given in ISO15626.
