1.1本欧洲标准适用于膨胀比大于200:1的高膨胀泡沫发生器，其外部电源的唯一来源是设备供水的压力和/或流量。这是由消防和救援服务使用，并包含其规范和测试程序。 注1:在本文档中，术语“泡沫发生器”也指“高膨胀泡沫发生器”。 注2:使用的例子有船舶发动机舱和舱底，地下停车场，隧道，地下室，化学品储存区和储罐箱。一些高膨胀发生器也可用于抽烟或通风（见附件A）。 1.2本文件处理与高膨胀泡沫发生器有关的所有重大危险，危险情况或危险事件（见附件B），除了噪声外，按照预期使用和在误用条件下，可合理预见的制造商。 1.3本文件不适用于在EN发布之前制造的高膨胀泡沫发生器

1.1 This document applies to high expansion foam generators, having an expansion ratio greater than 200:1, whose only source of external power is the pressure and/or flow of the water supply to the device. This is used by fire and rescue services and contains their specification and test procedures. NOTE In this document, the term"foam generator" also refers to "high expansion foam generator". 1.2 This document deals with all significant hazards, hazardous situations or hazardous events, with the exception of noise, relevant to high expansion foam generator, when it is used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. 1.3 This document does not cover misting applications. 1.4 This document is not applicable to high expansion foam generators which have been manufactured before its date of publication as EN.
