Journey continues on Veracity, DNV's trusted digital platform.
Non-destructive testing (NDT) is the process of inspecting, examining or evaluating materials, components or assemblies for discontinuities or differences in properties without destroying the usability of the part or system. In other words, when the inspection or investigation is complete, the part can still be used.
DNV has been accredited by the RvA (17024) to certify non-destructive testing specialists in accordance with the international standard NEN-EN-ISO 9712 as of 1 July 2021.
