34、04-8:2017 (E)1 Scope1.1 This document specifies requirements for gaseous fire-extinguishing systems, with respect to the IG-100 extinguishant. It includes details of physical properties, specification, usage and safety aspects.1.2 This document is applicable for systems operating at nominal pressure

35、s of 200 bar at 15 C 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 indispensable for

36、 its application. For dated references, only the edition cited applies.
