This International Standard specifies requirements for the components and method of installation of pressurized
irrigation system control heads, referred to hereinafter as irrigation control heads, with a nominal size of up to and
including 200 mm.
This International Standard is applicable only to the above-ground components of irrigation control heads for
sprinkler irrigation and micro-irrigation (mini-sprinklers, drip irrigation, etc.). It is applicable to the basic irrigation
control head, on which other irrigation control and command components (electrical, electronic and hydraulic) may
be assembled, but does not deal with these additional components.
This International Standard is not applicable to systems and/or components that may be required to prevent the
water from freezing in the irrigation control head, such as dry-barrel hydrants or other types of hydrants.
This International Standard does not specify construction or operating requirements for the individual components
that make up the irrigation control head. These requirements are specified in the relevant standards for each
component.
Systems whose irrigation control heads contain components for the injection of agricultural chemicals should be
protected by backflow prevention system interlocks, injection line check valves and other safety devices in
accordance with local standards or regulations. This International Standard does not cover such equipment.
