This European Standard applies to meters fitted to irrigation machines and networks. These meters are used to meter the actual volume of irrigation water flowing through a fully charged, closed pipe, in order to manage consumption, and to invoice the volume of water distributed.
Irrigation water is likely to contain mineral and organic particles.

This document provides guidelines to choose material, to design, to prepare plans, and to install a solid set irrigation system to apply water to the irrigated area with the greatest possible efficiency.
This document covers sprinkler irrigation systems installed at the beginning of the irrigation season and removed at the end without moving any component, sprinkler or pipe, during the entire irrigation season.
It covers only solid set system components located on the field and upstream from a water supply point defined by a pressure and a flow.
This document does not cover permanent systems with buried pipes nor hand-movable portable systems.

This document provides a document to check and test, the proper operation and performance of a solid set irrigation system installed according to relevant design documents specified in EN 13742-1.

This document applies to irrigation hydrants intended to supply equipment for use in water distribution irrigation networks. The range of PN is that defined in EN 1074-1, i.e.: PN 10, PN 16, PN 25 and limited to PN 25.

This standard provides:
- principles and formulas for calculating water application intensity under sprinkler irrigation systems (fixed and moving);
- test methods and guidelines for measuring water application intensity under the different systems in laboratory and in field conditions.
It applies to stationary sprinkling systems: solid set sprinkler systems, automatic turf irrigation systems, sprinklers and sprayer for microirrigation systems, and to moving sprinkling systems: reel machine systems, centre pivot and moving laterals systems.

This standard describes the technical characteristics and requirements of hydraulic connection and control accessories to ensure a sufficient mechanical resistance for practical use, and specifies the relevant testing methods. It applies to accessories made of steel, brass, aluminium, Polypropylene, Polyethylene or PVC for use in irrigation systems up to a diameter of 250 mm.

ISO 8224-1:2002 specifies the operational characteristics of, and laboratory and field test methods for, traveller irrigation machines. It includes user-oriented technical information for presentation in the manufacturer's accompanying product literature, laboratory test procedures for evaluating the uniformity of water application on an irrigated strip by a machine operating within a specified range of conditions and for determining the maximum travelling rates the drive mechanism is able to achieve in response to specified operating conditions, and field test procedures for determining the uniformity of water application on a given irrigated strip under local conditions prevailing in the field at time of testing.
It is applicable only to traveller irrigation machine types, and not to other types such as centre-pivot or lateral irrigation machines.

This European Standard specifies the installation methods and the automatic turf irrigation system handover.
Annex A should be used as a check list for system handover (excluding pump stations).

This European Standard provides a document to test the performance of uniformity of water distribution of an automatic turf irrigation system in order to commission the system.

This European Standard specifies the technical and functional characteristics that shall be indicated by manufacturers of localised irrigation systems for user information to aid them in their choice of facilities and materials.
