<p>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).</p>
<p>The values measured and recorded can be used to compare the setting of the sprayer with the provisions authorized for the specific DRT.</p>
<p>The document is applicable for sprayers for both field and tree and bush crops. It does not apply to hand held and portable sprayers.</p>
<p>The following parameters are covered in this document:</p>
<p>a) spray pressure (pressure of the spray liquid and air in case of twin-fluid nozzles);</p>
<p>b) nozzle height (field crop sprayers);</p>
<p>c) fan rotational speed (for air assisted sprayers);</p>
<p>d) sprayer forward speed.</p>
<p>This document does not specify:</p>
<p>— the exact length of the recording period;</p>
<p>— the verification of the measured and recorded parameters;</p>
<p>— the requirements for data format and exchange because they are covered by other ISO standards.</p>
<p>This document does not specify which of the four parameters needs to be monitored.</p>
