Scope

NB/T 20003 specifies the non-destructive testing methods, quality classification of test results and recommended acceptance standards for nuclear is and mechanical equipment in nuclear power plants. This part of NB/T 20003 specifies the technical requirements and acceptance criteria for penetrant testing of mechanical equipment on nuclear is ands in nuclear power plants. This section is applicable to the detection of surface opening defects in materials, components and welded joints used in nuclear is and mechanical equipment of nuclear power plants during the manufacturing and installation process.
