34、7EN 15004-10:2017 (E)1 Scope1.1 This document specifies requirements for gaseous fire-extinguishing systems, with respect to the IG-541 extinguishant. It includes details of physical properties, specification, usage and safety aspects.1.2 This document is applicable for systems operating at nominal
35、pressures of 150 bar, 200 bar and 300 bar at 15 C. This does not preclude the use of other systems, although design data for other pressures are not available at this time.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispen
36、sable for its application. For dated references, only the edition cited applies.

37、(ISO 14520-1:2006, modified)3 Terms and definitionsFor the purposes of this document, the terms and definitions given in EN 15004-1 apply.4 Characteristics and uses4.1 GeneralIG541 is a colourless, odourless, electrically nonconductive gas with a density approximately the same as that of air.It is a
38、n inert gas mixture consisting nominally of 52 % nitrogen, 40 % argon and 8 % carbon dioxide. The mixture specification for IG-541 (based on 8 % carbon dioxide with tolerance of 5 %) is as follows:a) carbon dioxide percentage range 7,6 % to 8,4 %;b) argon percentage range 37,2 % to 42,8 %;c) nitroge
39、n percentage range 48,8 % to 55,2 %.Individual container or batch analysis is based on carbon dioxide measurement only.Extinguishant IG-541 shall comply with the specification shown in Table 1.The physical properties are shown in Table 2.IG-541 extinguishes fires mainly by a reduction of oxygen conc
