Abstract

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.

This standard contributes to the following Sustainable Development Goal
