European foreword
This document (prEN 12094-13:2022) 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 12094-13:2001.
In comparison with the previous edition, the following technical modifications have been made:
a) The whole structure of the document has been adapted to Regulation (EU) No. 305/2011 on
construction products (CPR);
b) Clause 4 Requirements has been renamed to Characteristics;
c) Clause 4.1 General design: Material specification for metal has been deleted;
d) Clause 4.2 Connection threads has been deleted;
e) Clause 4.5 flow way in combination with 5.3 Compliance has been deleted;
f) Clause 6 Marking has been deleted;
g) Clause 7 Evaluation and conformity has been renamed and restructured;
h) Annex ZA has been adopted according to the requirements of the CPR;
i) Bibliography has been deleted.
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) No. 305/2011.
For relationship with Regulation (EU) No. 305/2011, see informative Annex ZA, which is an integral part
of this document.
This document is part of the series of standards EN 12094, Fixed firefighting systems — Components for
gas extinguishing systems, which consist of the following parts:

1 Scope
This document specifies the characteristics and describes test methods for check and non-return valves
for CO , inert gas or halocarbon gas fire extinguishing systems.
Non-return and check valves allow the passage in the direction of flow and they prevent flow in the
reverse direction.
This document is applicable to check valves installed between container valve and manifold and non-
return valves installed in pilot lines, except those valves which are tested in combination with non-
electrical control devices.
