ISO/TC 23/SC 6/WG 25 - Unmanned Aerial Spraying System (UASS)

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).

This document, when used together with ISO 16119-1, specifies the requirements and the means for verification of the design and performance of unmanned aerial spraying systems (UASS) mounted on unmanned aircraft systems (UAS) for application of plant protection products (PPPs) in agriculture, forestry, turf and amenity areas, with regard to minimising the potential risk of environmental contamination during use, including misuse foreseeable by the UASS manufacturer. The requirements of this document take precedence over those of ISO 16119-1. The ISO 23117 series does not cover human safety aspects of UASS’s or safety aspects concerning UAS’s, remote pilots or bystanders. This document is not applicable to UASS mounted on UASs with a maximum take-off mass greater than 150 kg. This document is not applicable to UASSs manufactured before the date of its publication.
