GB/T 20702-2006 in English

《GB/T 20702-2006气体灭火剂灭火性能测试方法》由TC113（全国消防标准化技术委员会）归口，TC113SC3（全国消防标准化技术委员会灭火剂分会）执行，主管部门为应急管理部。
本标准规定了使用杯式燃烧器确定气体灭火剂灭可燃气体和可燃液体火时，灭火剂在空气中灭火浓度的试验方法和在三体系中基于燃烧性曲线数据，测定灭火剂的惰化浓度的试验方法。本标准适用于气体灭火剂灭火浓度和惰化浓度的测试。

Scope

This standard specifies the test method for determining the extinguishing concentration of the extinguishing agent in the air when using a cup burner to extinguish combustible gas and flammable liquid fires and in the ternary system (fuel, extinguishing agent, air) based on the combustibility curve Data, test method for determining the inert concentration of fire extinguishing agents. This standard is applicable to the test of fire extinguishing concentration and inerting concentration of gas fire extinguishing agent.
