Fixed firefighting systems. Components for gas extinguishing systems - Requirements and test methods for nozzles for CO2 systems Ingestion-build-82396 Description of PTV injection systemThis document specifies requirements and test methods for room protection nozzles which introduce the extinguishing agent into a CO2 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
