European foreword
This document (prEN 12094-8:2016) has been prepared by Technical Committee CEN/TC 191 “Fixed
firefighting systems”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 12094-8:2006.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of Regulation (EU) 305/2011.
For relationship with Regulation (EU) 305/2011, see informative Annex ZA, which is an integral part of
this document.
EN 12094, Fixed firefighting systems - Components for gas extinguishing systems consists of the following
parts:
— Part 1: Requirements and test methods for electrical automatic control and delay devices
— Part 2: Requirements and test methods for non-electrical automatic control and delay devices
— Part 3: Requirements and test methods for manual triggering and stop devices
— Part 4: Requirements and test methods for container valve assemblies and their actuators

1 Scope
This European Standard specifies product characteristics and describes test methods for flexible and
rigid connectors intended to be used in gas extinguishing systems (i.e. CO , inert gas or halocarbon gas)
installed in buildings as a part of a complete operating system.
This European Standard is applicable to the following connectors:
— Type 1 and Type 5: used between container valves and the manifold;
— Type 3: used in pneumatic pilot lines;
— Type 2 and Type 4: used in distribution pipework of fire extinguishing installations downstream of
the manifold/selector valve.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
CO -high-pressure installation
fire extinguishing installation in which the CO is stored at ambient temperature
EXAMPLE The pressure of the CO in storage is p = 58,6 bar at 21 °C.
2 abs
2.2
CO -low-pressure installation
fire extinguishing installation in which the CO is stored at low temperature
Note 1 to entry: Normally −19 °C to −21 °C.
2.3
fill ratio

one or more of the elements fluorine, chlorine, bromine or iodine
2.6
halocarbon gas installation
fire extinguishing installation in which the halocarbon gas is stored at ambient temperature
2.7
inert gas
