NB/T 20219-2013Diagnosis for Valves of Nuclear Power Plants (English PDF)

NB/T 20219-2013 is the English-translated version of 核电厂阀门诊断.

NB/T 20219-2013 is a recommended energy industry standard of China dealing with the diagnosis of valves in nuclear power plants. Its subject is the assessment of valve condition in the plant, a matter of operation and maintenance rather than of valve manufacture.

It sits under the Chinese classification F23 and the international class 27.120.99, which covers nuclear power plant equipment not classified elsewhere. Three documents are cited: GB/T 22137.2-2008, NB/T 20010.8-2010 and DL/T 861-2004.

It was put into effect by the National Energy Administration, which also entered it on the 2013 industry standard record. Issued on 8 June 2013, it has applied since 1 October 2013.
