21、4 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. Pillar fire hydrants consist of one or more valves and connection outlets in a column shape, which emerges from below gro

22、und level, 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 potential adverse effects on

23、 the 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 a

24、waiting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of this product remain in force.

25、dard specifies the minimum requirements, test methods, marking and evaluation of conformity for pillar hydrants for fire fighting purposes: to be installed in a water distribution system; sizes DN 80, DN 100 and DN 150; suitable for an allowable operating pressure, PFA, of PN 16 with or without drai

26、n facility; having vertical or horizontal, flanged, socket or spigot inlet; with one or two outlets and having outlets to national requirements; globe (screw down) or gate valve type. This European Standard also provides for the evaluation of conformity of the pillar fire hydrants to the requirement

27、s 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 re

28、quirements. 2 Normative references The following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 68
