Fixed firefighting systems. Components for gas extinguishing systems. Part 7: Requirements and test methods for nozzles for CO2 systems
Soveltamisala
Suomenkielistä soveltamisalaa ei ole saatavissa.
This European Standard specifies requirements and test methods for nozzles which introduce the extinguishing agent into a CO 2 protected zone. The design of the nozzles will influence discharge rate and thus the pressure drop in the piping network. The
extinguishing agent normally arrives at the nozzle in two-phase flow form (liquid-gaseous mixture). It expands into the protected volume to form a gas or a gas-and-dry-ice mixture depending on the nozzle type. This standard should only be used as guidance for testing nozzles which work on different principles.
