Overview

ISO 24253-1:2015 - Crop protection equipment: Spray deposition test for field crop - Part 1: Measurement in a horizontal plane defines standardized field procedures to measure spray deposition on a horizontal surface. It applies to horizontal boom sprayers with downward-directed application and specifies how to quantify the quantity and distribution of spray on ground surfaces (bare soil or short mown grass). The standard enables meaningful comparisons between different field experiments and with laboratory tests (e.g., ISO 5682-2), but is not intended for regulatory use.

Key topics and technical requirements

Test principle: Measure spray deposition on artificial collectors placed on a horizontal plane to determine mean deposition and its variation.
Test area: Use bare soil or grass ≤ 8 cm; sampling layout must avoid boom end and machine turbulence and include measurements on both sides and along the boom. Track length must allow steady output (suggested minimums: 10 m for speeds ≤ 2 m/s; 20 m for speeds ≤ 4 m/s).
Meteorological monitoring: Measure wind speed/direction, temperature and humidity at (2 ± 0.1) m height. Wind sampling frequency ≥ 1 Hz. Prefer wind speeds ≤ 2 m/s and stable conditions (std dev ≤ ±1 m/s). Temperature range 5 °C–35 °C; report temperature inversions.
Tracers and collectors: Use safe, stable tracers (e.g., fluorescent dyes, metal ions) with recovery ≥ 90% (preferably >95%). Collectors must be pre-tested for recovery and background emission (blank ≤ 0.1% of sprayed average; background CV
