DNV revises class guideline for Non-destructive Testing

On January 27th, DNV published revised guideline for Non-destructive Testing as document DNV-CG-0051, which supersedes the December 2015 edition.

Besides editorial corrections, the document is now aligned with IACS UR W33 Non-destructive testing of ship hull steel welds - Rev.1 Corr1 Aug 2021 and IACS UR W34 Advanced non-destructive testing of materials and welds - New Dec 2019.

Moreover, the former guideline for Non-destructive Testing of Thermo-mechanically Controlled Processed (TMCP) materials and root area of single side welds have been included as requirements in Section 7. In addition, the new appendix gives a guideline for qualification of Phased Array Ultrasonic Testing (PAUT) and Time of flight diffraction (TOFD) procedures.
