DIN 25435-7:2014-01

This document is applicable for in-service inspections by radiographic testing conducted on components in the reactor coolant circuit of light water reactors. This standard is also applicable to other components of nuclear installations. Test systems for the validation of inhomogeneities (surface and volume) and requirements for test personnel, test devices, the preparation of test and device systems, the implementation of the testing as well as the recording are defined. An in-service radiographic test in respect to corrosion and wall thickness abrasion of base material areas is not an object of this standard. The committee responsible for this standard is NA 062-07-47 AA "Zerstörungsfreie Prüfung in der Kerntechnik" ("Non-destructive testing in nuclear technology") at DIN.
