Resumen:
This 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 nozzle type. This standard is not applicable to local application nozzles.
