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.

EN 14339:2005 (E)
The manufacturer shall ensure:
– initial type testing in accordance with this European Standard is initiated and carried out (where relevant,
under the control of a product certification body); and
– that the product continuously complies with the initial type testing samples, for which compliance with
this European Standard has been verified.
The manufacturer shall always retain the overall control and shall have the necessary competence to take
responsibility for the product.
The manufacturer shall be fully responsible for the conformity of the hydrant to all relevant regulatory
requirements. However, where the manufacturer uses components already shown to conform to those
requirements relevant for that component (e.g. by CE marking), the manufacturer is not required to repeat the
evaluation which leads to such conformity. Where the manufacturer uses components not shown to conform,
it is his responsibility to undertake the necessary evaluation to show conformity.
