NBN ISO 23117-2:2025

This document specifies field measurements of spray deposition to determine the quantity and distribution of spray in a plane surface area in the transverse direction to the flight direction, treated by specific Unmanned Agricultural Aerial Sprayer (UAAS) with downward directed application.

These field measurements can be used to determine the effective swath width of UAAS.

This document is not appropriate for evaluating spray deposition within a crop canopy (three-dimensional deposition). It is not appropriate for those spraying systems which rely on the presence of a crop canopy for efficient spray deposition (for example directed spraying, electrostatic charged spraying, very fine sprays).
