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 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.

ISO 16823:2012 specifies the principles of transmission techniques. Transmission techniques can be used for: a) detection of imperfections; b) determination of attenuation. The general principles required for the use of ultrasonic examination of industrial products are described in ISO 16810. The transmission technique is used for examination of flat products, e.g. plates and sheets. Further, it is used for examinations e.g.: 1) where the shape, dimensions or orientation of possible imperfections are unfavourable for direct reflection; 2) in materials with high attenuation; 3) in thin products.
