Fixed firefighting systems - Gas extinguishing systems - Part 7: Physical properties and system design of gas extinguishing systems for IG-01 extinguishant

This document gives specific requirements for gaseous fire-extinguishing systems, with respect to the IG-01 extinguishant. It includes details of physical properties, specification, usage and safety aspects and is applicable to systems operating at nominal pressure of 160 bar, 200 bar and 300 bar at 15 °C. This does not preclude the use of other systems; however, design data for other pressures were not available at time of publication.

1 Scope
1.1 This part of EN 15004 contains specific requirements for gaseous fire-extinguishing systems, with
respect to the IG-01 extinguishant. It includes details of physical properties, specification, usage and safety
aspects.
1.2 This part of EN 15004 covers systems operating at nominal pressures of 160 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 references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.
EN 15004-1, Gaseous fire-extinguishing systems — Physical properties and system design — Part 1: General
requirements.
3 Terms and definitions
For the purposes of this part of EN 15004, the terms and definitions given in EN 15004-1 apply.
4 Characteristics and uses
4.1 General
Extinguishant IG-01 shall comply with the specification shown in Table 1.
IG-01 is a colourless, odourless, electrically non-conductive gas at ambient (20 °C) temperatures, with a
density approximately 1,4 times that of air.
The physical properties are shown in Table 2.
IG-01 extinguishes fires mainly by a reduction of the oxygen concentration in the atmosphere of the hazard
enclosure.
