Introduction

The purpose of a Fire Hydrant installation is to provide a connection (i.e. hydrant) to the water main towhich the fire brigade can connect firefighting equipment. Underground hydrants consist of valve/sand connection outlet/s in an underground chamber with a surface manhole cover.

This standard is in conformity with the general requirements established by CEN/TC 164 in the field ofWater Supply. Products in permanent or temporary contact with water intended for humanconsumption should not affect the quality of the water. This Standard therefore does not contravenethe Directives 75/400/EEC and 80/778/EEC.

7.1 General

The compliance of an underground hydrant with the requirements of this standard and with the statedvalues shall be demonstrated by:

� initial type testing,

� factory production control by the manufacturer, including product assessment.

For the purposes of testing, hydrants may be grouped into families where it is considered that theselected property is common to all hydrants within that family.

7.2 Type testing

7.2.1 Initial type testing

Initial type testing shall be performed on first application of this standard. Tests previously performedin accordance with the provisions of this standard (same product, same characteristic(s), test method,sampling procedure, system of attestation of conformity, etc.) may be taken into account. In addition,initial type testing shall be performed at the beginning of the production of a new hydrant type (unlessa member of the same family) or at the beginning of a new method of production (where this mayaffect the stated properties).

Where characteristics are determined on the basis of conformity with other product standards(e.g. valves and surface boxes and covers), these characteristics need not be reassessed providedthat the hydrant manufacturer ensures the validity of the results. Products CE marked in accordancewith appropriate harmonised European specifications may be presumed to have the performancesstated of them, although this does not replace the responsibility of the hydrant manufacturer to ensurethat the hydrant as a whole is correctly designed and its component products have the necessaryperformance values.

All characteristics in clauses 4, 5.1 and 9 shall be subject to initial type testing. The results of all typetests shall be recorded and held by the manufacturer for at least 5 years.

7.3 Factory production control (FPC)

7.3.1 General

The manufacturer shall establish, document and maintain an FPC system to ensure that the productsplaced on the market conform with the stated performance characteristics. The FPC system shallconsist of procedures, regular inspections and tests and/or assessments and the use of the results tocontrol raw and other incoming materials or components, equipment, the production process and theproduct.

An FPC system conforming with the requirements of EN ISO 9001 and made specific to therequirements of this standard, is considered to satisfy the above requirements.

prEN 14339:2001 (E)

17

The results of inspections, tests or assessments requiring action shall be recorded, as shall any actiontaken. The action to be taken when control values or criteria are not met shall be recorded.

7.3.2 Equipment

All weighing, measuring and testing equipment shall be calibrated and regularly inspected accordingto documented procedures, frequencies and criteria.

7.3.3 Raw materials and components

The specifications of all incoming raw materials and components shall be documented, as shall theinspection scheme for ensuring their conformity.
