Equipment for crop protection - Method for measurement of potential spray drift from horizontal boom sprayers by the use of a test bench
ISO 22401:2015 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.
ISO 22401:2015 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.
ISO 22401:2015 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.
NOTE: Further investigations and tests are on-going to consider other parameters for classification aims (e.g. air assisted system, forward speed, nozzle spacing and orientation).
