This part of ISO 8224 specifies the operational characteristics of, and laboratory and field test methods for, traveller irrigation machines. It includes — user-oriented technical information for inclusion 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 machines and not to other types of irrigation machine such as centre-pivot and moving lateral irrigation machines.
