irrigation hydrant valve apparatus intended to ensure the delivery of irrigation water supplied to a user network from a pressurised distribution network which is generally subterranean buried The irrigation hydrant consists of the body of the hydrant and one or more distribution outlets fitted to it. It is characterised by the diameter of the body and by the diameters of the outlets (see Figure 1). It features at least a "shut-off" function and a "metering" function. It may also integrate the "flow-rate limitation" and "pressure regulation" functions. NOTE Throughout the rest of this document, "irrigation hydrant" is also referred to as the hydrant. 3.2 pressurised water distribution network for irrigation collective network which is generally positioned underground which supplies irrigation water to several user networks 3.3 user network distribution network belonging to the user which supplies land irrigation systems 3.4 nominal diameter (DN) alpha-numerical designation of dimension for the components of a piping network used for reference purposes. It comprises the letters DN followed by a whole number without units, which is indirectly related to the actual dimensions, in millimetres, of the bore or the external diameter of the end connections NOTE The number which follows the letters DN does not represent a measurable value and should not be used for calculation purposes, except where specified in the relevant standard. [EN ISO 6708:1995] 3.5 nominal pressure (PN) alpha-numerical term used for reference purposes and relating to a combination of mechanical and dimensional characteristics of a pipeline network component. It comprises the letters PN followed by a whole number without unit NOTE 1 The number following the letters PN does not represent a measurable value and it should not be used for calculation purposes except where specified in the relevant standard. NOTE 2 The term PN is not significant unless it is associated with the number of the relevant component standard. NOTE 3 The permissible pressure of a component of a pipeline network depends on the PN value, the material and the design of the component, its permissible temperature, etc., and i
