scope:

NEN-ISO 24253-1 specifies field measurements of spray deposition to determine the quantity and distribution of spray in a plane surface area, treated by horizontal boom sprayers with downward directed application. This part of ISO 24253 allows flexibility in the arrangement of field tests, but specifies standardized measurement procedures that are useful to be able to compare the results from different field experiments or to compare with laboratory tests, such as that described in ISO 5682-2.[1] This part of ISO 24253 may not be appropriate for those spraying systems which rely on the presence of a crop canopy for efficient deposition (for example directed spraying, electrostatic charged spraying, very fine spraying, variable rate spraying). This International Standard is not intended for use in or for a regulatory framework.
