PREN 17290-2018 Non-destructive testing - Ultrasonic testing - Examination for loss of thickness due to erosion and/or corrosion using the TOFD technique
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.
