This document specifies the application of the time-of-flight diffraction (TOFD) technique in testing of metals for quantifying loss of thickness due to erosion and/or corrosion.
This document applies to all types of corrosion and/or erosion damage, particularly those defined in EN ISO 16809.
This document applies to unalloyed or low-alloyed steels.
It applies to components with a nominal thickness greater than or equal to 6 mm. For smaller thicknesses, feasibility tests are performed to validate the test technique.
For other materials, feasibility tests are essential, too.
The TOFD technique can be used as a stand-alone technique or in combination with other non-destructive testing techniques, for in-service testing, in order to detect material loss caused by erosion and/or corrosion.
This technique is based on analysis of TOFD images using reflected and/or diffracted ultrasonic signals.
This document does not specify acceptance levels.
