The object of isO 22369 is to provide uniform procedures for the determination of the drift reducing performance of spraying equipment. iv BS ISO 22369-1:2006 Crop protection equipment Drift classification of spraying equipment - Part 1: Classes Scope This part of IsO 22369 specifies the drift classification of spraying equipment and defines the spray drift reductionclasses. This part of IsO 22369 is applicable to spraying equipment used in applications such as arable field crops, in bush and tree crops, and in horticulture and forestry. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 driftreduction dred difference between the spray drift deposition or collection of the candidate spraying equipment (Cs) and that of a reference spray system (RS), for the same distance and test procedure, calculated as dRSdRS dred Classification The classification is based on the comparison of the candidate spraying equipment with the reference spraying
