11、op protection chemicals to arable crops. It also specifies a verification procedure. This standard is applicable to configurations of tractor mounted, trailed and self-propelled sprayers with a boom width of greater than 6.0 m. Small boom sprayers with boom widths of less than 6.0 m that could be us
12、ed in amenity areas or horticultural production are not within the scope of this standard. The purpose of the standard is to enable recommendations for the spatially variable application of plant protection products to be made using the defined five performance levels. Performance levels are defined
13、 in relation to the range of dose rates that can be delivered and the spatial resolution of the application only. It is recognized that other application factors and variables can be adjusted as part of the operation and control strategy of a spatially variable application systems. Such variables ma
14、y include: volume rate; spray liquid concentration; spray quality; nozzle angle; forward speed; boom height. Some of these variables may be changed in order to effect a change in the applied dose rate and in this way are covered by this standard. Matching delivery conditions other than dose rate at
15、defined resolution is beyond the scope of this standard. 2 Normative references The following referenced documents are indispensable for the application of this document.
