scope:

This Part of ISO 22369 specifies the drift classification procedure for field crop sprayers by the measurement of potential spray drift with the use of a test bench and it allows the allocation of the spray drift reduction classes specified by ISO 22369-1.

This International Standard is applicable to mounted, trailed and self-propelled field crop sprayers used in arable crops.

It is intended for booms using a uniform set of spray generators and not specifically for band sprayers and sprayers with attachments designed to spray within, and directed into the canopy.

It is applicable where comparative assessment or classification of the relative spray drift potential from spray generators (e.g. nozzles) or spray liquids is needed.

The object of this Part of ISO 22369 is to determine the potential spray drift generated by field crop sprayers through the use of a test bench and to compare the values obtained with those of a reference spray system in order to rate (classify) the field crop sprayers.

This Part of ISO 22369 allows, after checking the reference spraying system in accordance with the criteria adopted in ISO 22369-2, to assess the potential spray drift value of the candidate spraying equipment and to get a quick and simple classification of these spraying equipment according to their drift reducing performance.

The application of this International Standard may support advisory services for farmers, the product development and legal certification and classification schemes.

This Part of ISO 22369 is intended to be used together with ISO 22369-1.
