NB/T 20338-2015In situ measurements for response time of resistance temperature detectors important to safety in nuclear power plants (English PDF)

NB/T 20338-2015 is the English-translated version of 核电厂安全重要电阻温度计响应时间原位测量.

NB/T 20338-2015 is the recommended Chinese energy industry standard for the in situ measurement of the response time of resistance temperature detectors important to safety in nuclear power plants.

It defines what in situ response time measurement means, recommends the test methods to be used and sets the corresponding test requirements. The measurement methods it gives are recommended for the case where a particular test or a physical analysis has shown a significant shift in the response time of the resistance thermometers.

It applies to resistance thermometers important to safety in nuclear power plants, and thermometers used in other reactors may follow it as a reference. It quotes NB/T 20148-2012. Issued on 2 April 2015, it has applied since 1 September 2015.
