Non-destructive testing - Ultrasonic testing - Examination for loss of thickness due to erosion and/or corrosion using the TOFD technique

active, Most Current
Organization: CEN
Publication Date: 1 October 2021
Status: active
Page Count: 26
ICS Code (Non-destructive testing): 19.100
scope:

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 ≥ 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.
