Μόνιμα συστήματα πυρόσβεσης - Συστήματα κατάσβεσης με αέριο - Μέρος 9: Φυσικές ιδιότητες και σχεδιασμός συστημάτων με κατασβεστικό υλικό IG-55 (ISO 14520-14:2005, τροποποιημένο)

This document gives specific requirements for gaseous fire-extinguishing systems, with respect to the IG-55 extinguishant. It includes details of physical properties, specification, usage and safety aspects and is applicable to systems operating at nominal pressure of 150 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.
