ISO 16119-4:2014

Overview

ISO 16119-4:2014 - Agricultural and forestry machinery - Environmental requirements for sprayers - Part 4: Fixed and semi-mobile sprayers specifies environmental design and verification requirements for fixed and semi-mobile sprayers. The standard focuses on minimizing the risk of environmental contamination during normal use and foreseeable misuse. It is intended to be used together with ISO 16119‑1 (general requirements); where Part 4 differs, its requirements take precedence. ISO 16119-4:2014 does not cover safety aspects (see ISO 4254‑6), space/spatial treatments, or sprayers manufactured before its publication.

Key technical topics and requirements

ISO 16119-4:2014 defines technical requirements and verification means for core sprayer components and operations related to environmental protection:

• Pump/tank unit: requirements for static leaks, residual volume, tank design and overfilling prevention.
• Lines, filters and measuring systems: leak minimization, backflow prevention and provision for test equipment connections.
• Pump performance: pulsation and flow considerations (see normative Annexes on backflow and pump pulsations).
• Dose/volume adjustment and calibration: pressure adjustment devices, direct injection systems, and calibration aids to control dosing and reduce overdosing.
• Application unit details: nozzles, horizontal and vertical booms, spray guns/lances, pressure drop, drift control and autonomous application units.
• Cleaning and rinsing systems: internal cleaning of tanks, rinsing water tanks and cleaning devices for product containers to prevent residue dispersal.
• Verification, marking and documentation: prescribed verification methods, marking requirements and instruction handbook content to support correct use and maintenance.

The document references relevant test methods and standards (e.g., ISO 5682 series, ISO 13440, ISO 22368) to support verification.

Practical applications

ISO 16119-4:2014 is used to design, assess and certify sprayer installations where environmental contamination risk is a concern. Practical applications include:

• Designing fixed sprayers in greenhouses, nurseries and covered structures.
• Configuring semi-mobile systems where pump/tank and application units move independently.
• Developing cleaning and containment solutions to limit runoff, spills and water-supply contamination.
• Selecting and specifying nozzles, booms and injection systems to minimize spray drift and overdosing.
• Preparing verification protocols, marking and operator manuals for compliance.

Who should use this standard

• Sprayer manufacturers and equipment designers
• Agricultural and greenhouse system integrators
• Test laboratories and conformity assessors
• Farm managers, greenhouse operators and environmental/regulatory authorities
• Procurement specialists specifying fixed or semi-mobile spraying systems

Related standards

• ISO 16119‑1 (General requirements)
• ISO 5682 series (sprayer test methods)
• ISO 4254‑6 (safety for sprayers)
• ISO 22368 (cleaning systems) Using ISO 16119-4:2014 helps ensure fixed and semi-mobile sprayer systems meet recognized environmental requirements, reduce contamination risk, and provide verifiable performance for agricultural and forestry applications.
