气体灭火系统.物理特性和系统设计.第1部分:一般要求

[中文适用范围]： 本文件规定了建筑物、工厂或其他结构物中气体灭火系统的设计、安装、测试、维护和安全的要求并提出了建议，以及各种灭火剂的特性和适合用于灭火的火灾类型。它涵盖主要与建筑物、工厂和其他特定应用相关的全淹没系统，使用不导电的气体灭火剂，这些灭火剂在排放后不会留下残留物，并且目前有足够的数据可供适当的独立机构验证其性能和安全特性。本文件不适用于爆炸抑制。本文件并非表示有关当局批准其中列出的灭火剂，因为其他灭火剂也同样可以接受。CO2 不包括在其他国际标准中，因为它已包含在内。本文件适用于表 1 所列的灭火剂。它必须与表 1 中列出的 ISO 14520 系列中关于特定灭火剂的单独部分配合使用。1 表 1 — 列出的灭火剂 灭火剂 化学式 CAS 编号 国际标准 FK-5-1-12 十二氟-2-甲基戊-3-酮 CF3CF2C(O)CF(CF3)2 756-13-8 ISO 14520-5 HCFC-123 二氯三氟乙烷 CHCl2CF3 306-83-2 HCFC-22 一氯二氟甲烷 CHClF2 75-45-6 ISO 14520-6 HCFC-124 一氯四氟乙烷 CFClFCF3 2837-89-0 异丙烯基-1-甲基环己烯 C10H16 5989-27-5 HFC 125 五氟乙烷 CHF2CF3 354-33-6 ISO 14520-8 HFC 227ea 七氟丙烷 CF3CHFCF3 2252-84-8 ISO 14520-9 HFC 23 三氟甲烷 CHF3 75-46-7 ISO 14520-10 IG-01 氩气 Ar 74040-37-1 ISO 14520-12 IG-100 氮气 N2 7727-37-9 ISO 14520-13 氮气 (50 %) N2 7727-37-9 IG-55 氩气 (50 %) Ar 74040-37-1 ISO 14520-14 氮气 (52 %) N2 7727-37-9 IG-541 氩气 (40 %) Ar 74040-37-1 ISO 14520-15 二氧化碳 (8 %) CO2 124-38-9 卤化碳混合物 55 E-1-氯-3,3,3-三氟丙烯 (50 % 质量比) CF3CHCHCl 102687-65-0 ISO 14520-17 十二氟-2-甲基戊-3-酮 (50 % 质量比) CF3CF2C(O)CF(CF3)2 756-13-8 [外文原描述]： This document specifies requirements and gives recommendations for the design, installation, testing, maintenance and safety of gaseous firefighting systems in buildings, plants or other structures, and the characteristics of the various extinguishants and types of fire for which they are a suitable extinguishing medium. It covers total flooding systems primarily related to buildings, plants and other specific applications, utilizing electrically non-conducting gaseous fire extinguishants that do not leave a residue after discharge and for which there are sufficient data currently available to enable validation of performance and safety characteristics by an appropriate independent authority. This document does not apply to explosion suppression. This document is not intended to indicate approval of the extinguishants listed therein by the appropriate authorities, as other extinguishants can be equally acceptable. CO 2 is not included as it is covered by other International Standards. This document applies to the extinguishants listed in Table 1 . It is essential that it be used in conjunction with the separate parts of the ISO 14520 series for specific extinguishants, as cited in Table 1 .
