1 Scope

Part 1 of GB 15322 covers the point-type combustible gas detector used in industry and commerce — the fixed head mounted in a plant room, a boiler house or a filling station that alarms before a leak reaches the lower explosive limit. The 2026 edition is a substantial rewrite: thirty clauses of requirements and thirty-six test methods, covering the alarm set point and accuracy, the response and recovery times, the behaviour under high concentration and after poisoning of the sensor, the explosion-proof construction, the electrical safety and electromagnetic compatibility, and the climatic and mechanical endurance. It replaces GB 15322.1-2019 from 1 August 2027. Issued on 28 January 2026. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the edition it replaces are taken from there.
