Non-destructive testing — Ultrasonic testing — Through-transmission technique

This document specifies the principles of ultrasonic through-transmission techniques.

Through-transmission techniques can be used for:

—???? detection of discontinuities;

—???? determination of sound attenuation.

The general principles required for the use of ultrasonic testing of industrial products are described in ISO?16810.

The through-transmission technique is used for the testing of flat products, e.g. plates and sheets.

Further, it can be used for tests, for example:

—???? where the shape, dimensions or orientation of possible discontinuities are unfavourable for direct reflection;

—???? of materials with high sound attenuation;

—???? on thin test objects.
