GB/T 47572-2026 Agricultural sprayers—Recording of spray drift parameters

Scope

This document specifies the requirements for automatically measuring and recording the operating parameters that affect spray drift and are controllable by the operator under specific drift reduction technologies (DRTs).
The measured and recorded values can be used to compare the sprayer settings with the requirements of specific DRTs.
This document applies to sprayers used for field, shrub, and tree crops, but not to handheld and portable sprayers.
This document covers the following parameters:
a) Spray pressure (spray liquid pressure and air pressure for two-phase flow nozzles);
b) Nozzle height (for field crop sprayers);
c) Fan speed (for air-assisted sprayers);
d) Sprayer forward speed.
This document does not specify:
——The exact duration of the recording cycle;
——The verification of measured and recorded parameters;
——Data format and exchange requirements already covered by other current standards.
This document does not specify which of the four parameters needs to be monitored.
