Scope
NB/T 20328.3-2015 is the English-translated version of 核电厂核岛机械设备无损检测另一规范 第3部分:射线检测.
NB/T 20328.3-2015 is the radiographic testing part of the recommended Chinese energy industry standard on the non-destructive testing of nuclear island mechanical components in nuclear power plants.
It sets the technical requirements and the acceptance criteria for examination with X-rays and gamma rays of the machinery and equipment used in the nuclear island.
Its field of application is the radiographic examination of butt welded joints and of castings during the manufacture and the installation of that machinery and equipment.
It works with the general part NB/T 20328.1 and cites GB 11533, GB 18871, GBZ 117, GBZ 132 and ASTM E446, ASTM E186 and ASTM E280. Issued on 2 April 2015, it has applied since 1 September 2015.
