This document defines requirements on the electronic measurements (during spray operation)
and recording of operator-controlled application parameters that influence spray drift,
when specified for certain drift reduction technologies (DRT).
The values measured and recorded can be used to compare the setting of the sprayer
with the provisions authorized for the specific DRT.
The document is applicable for sprayers for both field and tree and bush crops. It
does not apply to hand held and portable sprayers.
The following parameters are covered in this document:
a) spray pressure (pressure of the spray liquid and air in case of twin-fluid nozzles);
b) nozzle height (field crop sprayers);
c)
fan rotational speed (for air assisted sprayers);
d) sprayer forward speed.
This document does not specify:
— the exact length of the recording period;
— the verification of the measured and recorded parameters;
