ICS Code (Non-destructive testing): 19.100
scope:

This document gives guidance for applying ultrasonic testing with arrays using FMC/TFM techniques. It is intended to promote the adoption of good practice either at the manufacturing stage or for in-service testing of existing installations or for repairs.

Some examples of applications considered in this document, deal with characterisation and sizing in damage assessment.

When testing welds ISO 23864 applies.

A key benefit of using FMC/TFM techniques is that the area within the test volume is presented as an image, which is created by synthetic focusing of the received sound field at each pixel. Comparison with the conventional phased array technique is given in Annex A.

Materials considered are low-alloyed carbon steel, but some recommendations are given for other materials (e.g. austenitic ones).

This document does not include acceptance levels for discontinuities.
