This document provides rules for structuring of systems in the domain of power supply systems, being supplementary to the general principles for the structuring of systems including structuring of information about systems specified in IEC 81346-1. Based on these principles, rules and guidance are given for the formulation of unambiguous reference designations for objects in any system. The…

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…
