Foreword
This European Standard (EN 14339:2005) has been prepared by Technical Committee CEN/TC 192 “Fire
service equipment”, the secretariat of which is held by BSI, in cooperation with CEN/TC164 "Water supply"
and CEN/TC 69 “Industrial Valves”.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by January 2006, and conflicting national standards shall be withdrawn at
the latest by January 2006.
This European Standard has been prepared under a mandate given to CEN by the European Commission
and the European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this European
Standard.
This is one of a series of standards for fire hydrants.
This is the first edition of this European Standard.
No International Standard exists for underground fire hydrants.

Introduction
The purpose of a fire hydrant installation is to provide a connection (i.e. hydrant) to the water main to which
the firefighter can connect firefighting equipment. Underground hydrants consist of one or more valves and
outlet connectors and are installed in an underground chamber with a surface box and intended primarily to
supply water for firefighting and also may be used by water utilities (as defined in 3.3).
This European Standard is in conformity with the general requirements already established by CEN/TC 164 in
the field of water supply.
In respect of quality of water intended for human consumption caused by the product covered by this
European Standard:
1) this European Standard provides no information as to whether the product may be used without
restriction in any of the Member States of the EU or EFTA;
2) it should be noted that, while awaiting the adoption of verifiable European criteria, existing national
regulations concerning the use and/or the characteristics of this product remain in force.
1 Scope
This European Standard specifies the requirements, test methods and marking applicable to underground fire
hydrants intended for fire fighting purposes:

facility;
having a vertical or horizontal, flanged, socket or spigot inlet;
with one or two outlets and having outlet/s to national requirements;
of globe (screw down) or gate valve type.
This European Standard also provides for the evaluation of conformity of the underground fire hydrants to the
requirements of this European Standard.
This European Standard applies to fire hydrants for potable and non-potable water and for filtered water.
Additional requirements may apply for other liquids.
Couplings connected to outlets are outside the scope of this European Standard and should conform to
national requirements.
