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

pending, Most Current
Organization: CEN
Publication Date: 1 September 2018
Status: pending
Page Count: 27
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 or erosion damage, particularly those defined in ISO 16809.

This test applies to unalloyed or low-alloyed steel materials.

It applies to components with a nominal thickness ≥ 6 mm. For smaller thicknesses feasibility tests will be performed to validate the technique. For other materials, feasibility tests are essential too.

The TOFD technique can be used here as a stand-alone technique or in combination with other nondestructive testing techniques, during manufacturing and for testing in-service, in order to detect material loss caused by erosion and/or corrosion.

This technique is based on analysis of TOFD images established using reflected and/or diffracted ultrasonic signals.

This document does not specify acceptance levels.
