标准摘要
[中文适用范围]： 本文件规定了用于制造低膨胀泡沫以控制、扑灭和抑制与水混溶的液体的火灾复燃的液体泡沫浓缩物的基本特性和性能。 规定了某些测试火灾的最低性能。 这些泡沫适用于扑灭与水混溶的液体火灾。 那些也符合 ISO 7203-1 标准的泡沫也适用于扑救与水不混溶的液体的火灾。 泡沫浓缩物可适用于非吸气式喷雾器或地下灭火液体火灾，但本文件中不包括这些应用的具体要求。 [外文原描述]： This document specifies the essential properties and performance of liquid foam concentrates used to make low-expansion foams for the control, extinction and inhibition of re-ignition of fires of water-miscible liquids. Minimum performance on certain test fires is specified. These foams are suitable for top application to fires of water-miscible liquids. Those foams that also comply with ISO 7203-1 are also suitable for top application to fires of water-immiscible liquids. The foam concentrates can be suitable for use in non-aspirating sprayers or for subsurface application to liquid fires, but requirements specific to those applications are not included in this document.
