Non-destructive testing

Die Annotation des Normtextes ČSN EN ISO 16823 (015023):

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
