1900 - 1949 Non-destructive testing of internal imperfections and surfaces

This specification deals with the ultrasonic testing of steel forgings, in comparison to SEP 1923 with computer-based data acquisition and processing for the detection of internal flaws by the pulse-echo technique.

The objectives of this specification are:
– to improve the reliability of test data,
– to enhance the reproducibility of results by recording of test data,
– to make all test data convertible into a format independent of equipment for subsequent analysis of the results,
– to provide an improved visualization by the use of appropriate software,
– to reduce acceptance testing.
