本标准规定了要求，并提供了有关设计，安装和测试的信息，并为特定危险接受固定的陆基水管系统提供了标准，并为各种危险组织提供了火灾试验方案。 这些要求对于船舶，飞机，车辆和移动消防设备或采矿业中的地下系统的监视系统无效。 但这些要求可作为其他固定消防系统的指导，但必须考虑到对其他消防用品的任何具体要求。 与防爆相关的维生素的方面超出了本文件的范围。 由于本文件的火灾测试场景适用于一组类似的应用，通过类比，watermist系统的成功性能也适用于该组，如附录A所定义。外延未涵盖。 该文件并不旨在用作水手的通用设计手册，因为不同的系统具有不同的特性，因此遵循不同的设计标准来满足其职责要求。 在没有一般化设计方法的情况下，本文件的目的在于对水系统进行全面火灾测试及其系统组成

This document specifies requirements and gives recommendations for the design, installation, inspection and maintenance of all types of fixed land based water mist systems. This document is intended to apply to water mist automatic nozzle systems and water mist deluge systems supplied by stand alone or pumped systems. The document covers only applications and occupancies which are covered by the fire test protocols of the EN 14972 series. Aspects of water mist associated with explosion protection and/or use within vehicles are not covered by this document. This document does not cover all legislative requirements. In certain countries specific national regulations apply and take precedence over this document. Users of this document are advised to inform themselves of the applicability or non-applicability for this document by their national responsible authorities.
