GB 15322.4-2019 Combustible gas detectors—Part 4:Line-type optical beam combustible gas detectors for industrial and commercial use
Abstract
This part of GB 15322 specifies the terms and definitions, classification, requirements, tests, inspection rules, and marking requirements for line-type flammable gas detectors used in industrial and commercial applications.
This part applies to line-type flammable gas detectors (hereinafter referred to as "detectors") that use the principle of spectral absorption to detect flammable gases and vapors such as hydrocarbons, ethers, esters, and alcohols, installed and used in industrial and commercial settings. Detectors with special performance used in industrial and commercial settings may also comply with this part, unless specific requirements are stipulated in other relevant standards.
