NB/T 20003.2-2010 Non-destructive testing for mechanical components in nuclear island of nuclear power plants-Part 2: Ultrasonic testing (English Version)
This part of NB/T 20003 specifies:
——General technical requirements for ultrasonic testing, relevant supplementary requirements and acceptance standards for specific types of workpieces;
——Technical requirements for contact ultrasonic pulse echo method to measure the thickness of workpieces. This section is applicable to the ultrasonic testing of raw materials and parts such as castings, plates, forgings, pipes and rods, as well as welded joints, is lation layers, surfacing layers, composite plates, etc. during the manufacturing and installation process of nuclear is and mechanical equipment in nuclear power plants.
