Overview
EN ISO 16122-3:2025 - Agricultural and forestry machinery - Inspection of sprayers in use - Part 3: Sprayers for bush and tree crops (ISO 16122-3:2024) specifies requirements and test methods for on‑site inspection of sprayers used in bush and tree crops. Used together with ISO 16122-1:2024, this standard focuses on the sprayer’s condition as it relates to environmental risk and its ability to deliver accurate, effective pesticide application. EN ISO 16122-3:2025 replaces the 2015 edition and is endorsed by CEN for application across member countries.
Key topics and technical requirements
The standard defines measurable inspection points and verification methods. Major technical topics include:
- Leaks and dripping: detection of static and dynamic leaks and spray dripping on machine parts.
- Pumps: capacity, pulsation and air chamber performance checks.
- Agitation: hydraulic and mechanical agitation verification to ensure spray mix homogeneity.
- Spray tanks: lid integrity, filling strainers, pressure compensation, content indicators, emptying and filling systems, induction hoppers and cleaning devices.
- Measuring and control systems: pressure indicators, regulation, pressure-drop checks and section equalization.
- Lines, pipes and hoses: integrity and leakage assessment.
- Filters: presence, isolation and serviceability of filter inserts.
- Nozzles and distribution: nozzle arrangement, dripping, shut‑off performance, adjustment and distribution uniformity.
- Blower and distribution systems: functionality checks for air‑assisted sprayers.
These topics reflect clauses and test methods laid out in the standard’s verification section and support objective assessment of a sprayer’s environmental risk and application performance.
Practical applications and users
EN ISO 16122-3:2025 is aimed at stakeholders involved in safe and sustainable pesticide application:
- Inspection bodies and regulatory authorities performing in‑use checks and compliance audits.
- Farmers and contractors operating sprayers for bush and tree crops (orchards, vineyards, hedgerows).
- Manufacturers, dealers and service technicians conducting maintenance, repair and pre‑sale inspections.
- Agricultural advisors and IPM (integrated pest management) consultants implementing best practice.
- Certification and training organizations developing inspection protocols and operator guidance.
Using this standard helps reduce environmental contamination, improve dosing accuracy and support compliance with pesticide‑use regulations.
Related standards and regulatory link
- Use in conjunction with ISO 16122-1:2024 (general inspection procedures and inspector protection).
- EN ISO 16122-3:2025 is developed under CEN and aligns with the objectives of EU Directive 2009/128/EC on sustainable pesticide use; when cited in the Official Journal it provides a voluntary presumption of conformity with related health, safety and environmental requirements.
