Scope
NB/T 10546-2021 is the English-translated version of 煤矿用乙烯传感器.
NB/T 10546-2021 is the Chinese energy industry standard for ethylene sensors used in coal mines. It classifies the sensors and sets their technical requirements, with terms such as calibration point and stability of zero, calibration and alarm points over time.
Test methods, inspection rules and requirements for marking, packaging, transport and storage are also given. The sensors concerned are installed in underground and opencast coal mines where ethylene may be present.
Mine safety equipment makers and testing centres rely on it. Issued on 7 January 2021, it has applied since 1 April 2021.
