Applies to the field measurement of quantities of spray deposit, applied using ground sprayers, on tree and bush crops.

This International Standard is applicable to the field measurement of quantities of spray deposit, applied using ground sprayers, on tree and bush crops.

It covers measurements of the volume or mass of spray deposits (both absolute and distribution) on target structures such as leaves, fruits and ground losses.

It does not deal with spray drift measurements. However, its use in combination with the protocol for field measurements of spray drift given in ISO22866 can result in a good evaluation of spray mass balance in tree or bush spraying when measuring airborne drift.

This International Standard allows for flexibility in the arrangement of field tests, specifying standardized measurement procedures that are useful for comparison of the results from different field experiments or laboratory tests, for example, using a vertical patternator.
