DIN EN 15004-4:2008 Fixed firefighting systems - Gas extinguishing systems - Part 4: Physical properties and system design of gas extinguishing systems for HFC 125 extinguishant (ISO 14520-8:2006, modified); English version of DIN EN 15004-4:2008-09
This document gives specific requirements for gaseous fire-extinguishing systems, with respect to the
HFC 125 extinguishant. It includes details of physical properties, specification, usage and safety aspects and
is applicable to systems operating at nominal pressures of 25 bar and 42 bar, superpressurized with nitrogen.
This does not preclude the use of other systems.
