• 19.100 Non-destructive testing

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.
