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.
