SEP 1926: Automated ultrasonic inspection of rotation symmetrical steel forgings with computer controlled data acquisition and processing

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.
