The standard sets the general, appearance and performance requirements, then twenty-three groups of test methods: alarm operation and set point, response time, orientation, repeatability, preheating, explosion protection, supply voltage and battery, insulation and electrical strength, electromagnetic compatibility, climatic and mechanical endurance, interference from other gases, resistance to poisoning, operation at low concentration, long-term stability and the response to carbon monoxide. It replaces GB 15322.2-2003 and GB 15322.5-2003, and is itself replaced by GB 15322.2-2026 from 1 August 2027. Issued on 14 October 2019, in force since 1 November 2020.
