标准范围

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，用于控制、熄灭和抑制水溶性液体火灾的再燃。规定了某些测试火灾的最低性能。这些泡沫适用于水溶性液体火灾的顶部应用。这些泡沫也符合ISO 7203-1的要求，也适用于水不混溶液体火灾的顶部应用。泡沫浓缩物可适用于非吸气式喷雾器或液体火灾的地下应用，但本文件不包括这些应用的具体要求。

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.
