scope:

NEN-ISO 22401 provides a test method to measure spray sedimentation from horizontal boom sprayers using a test bench. The sedimentation measure gives a value for potential spray drift. These measurements can be used to compare different sprayer setups on the same sprayer. This International Standard is applicable to mounted, trailed and self-propelled horizontal boom sprayers used in arable crops; and horizontal boom sprayers used for weed control in orchards/vineyards and spray application on horticultural crops. This International Standard is intended for booms using a uniform set of spray generators. If intended for spray drift classification of the sprayer, the comparison is limited to nozzle type, spray pressure and boom height.
