CEN/TC 334/WG 5 - Localized irrigation

The purpose of this Standard is to describe a localised irrigation hydraulic system and to specify a method to determine the uniformity in water distribution for each installation to be evaluated in the field.
This document applies to localised irrigation systems. It does not cover management practices.
This paper defines the methodology to be applied in the farm localised irrigation system evaluation.

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.
This standard is related to others that will be drawn up for each system component (technical characteristics and test methods).
This European standard defines localised irrigation systems, characterising the various components which comprise them.

This standard specifies the hydraulic and mechanical features necessary for defining the functioning of the emitting devices, whether or not equipped with compensating features, designed for use in localised irrigation systems.
The manner in which the manufacturers shall provide the basic engineering information for the design and use of the localised irrigation systems and the appropriate testing methods for checking and assuring the proper working order thereof are specified.
This standard applies to all the emitting devices listed in EN 13635:2001, 3.1, with the following restrictions:
- Micro-sprinklers, micro-sprayers or micro-jets are dealt with solely as components which aim is to wet a predetermined restricted area
   - Porous pipes are not included under this standard as a result of deeming the hydraulic features thereof to differ from the rest of the emitting devices.
   - Other devices such as misters, the essential function of which is that of creating a moist atmosphere more than watering as such, are not included.
