This International Standard specifies a test method to determine, on the one hand, the effect of fitting antidrip devices on nozzle flowrates, and, on the other hand, the opening and closing pressures.
It applies to antidrip devices of agricultural sprayer nozzles, except for hand-held or hand-operated sprayers.
