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的液体泡沫浓缩物的基本特性和性能，以控制、扑灭和抑制与水不混溶的液体的火灾重燃。 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不混溶的液体的火灾。 符合 ISO 7203-3 标准的泡沫也适用于扑灭与水混溶的液体火灾。 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，但这些应用的具体要求超出了本文件的范围。 [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, the extinction and the inhibition of reignition of fires of water-immiscible liquids. Minimum performance on certain test fires is specified. These foams are suitable for top application to fires of water-immiscible liquids. The foams that conform with ISO 7203-3 are also suitable for top application to fires of water-miscible liquids. The foam concentrates can be suitable for use in non-aspirating sprayers or for subsurface application to liquid fires, but the requirements specific to those applications are outside the scope of this document.
