Overview
EN ISO 16119-2:2013 (Corrected version 2017-03) - published by CEN - specifies environmental requirements and verification methods for horizontal boom sprayers used in agriculture and forestry. The standard focuses on minimizing the risk of environmental contamination during normal use and foreseeable misuse. It is intended to be used alongside ISO 16119-1 (General) and does not cover machine safety (see ISO 4254-6). EN ISO 16119-2 applies only to sprayers manufactured on or after its publication date.
Key topics and technical requirements
The standard defines scope, terminology and a list of significant hazards, then sets out requirements and verification methods for sprayer design and performance. Main technical topics include:
- General requirements for horizontal boom sprayer design and environmental protection
- Volume/hectare adjustment systems - requirements and verification of application rate controls
- Distribution and control of spray drift - measures to minimize off-target drift from booms and nozzles
- Cleaning requirements - procedures, acceptable residual limits and systems to enable safe cleaning
- Cleaning devices - design criteria for integrated or independent container/tank cleaning equipment
- Additional requirements for band sprayers, spray guns and lances
- Verification, marking and instruction handbook - tests, conformity checks and operator information
The document references relevant test and measurement standards for verification, including ISO 5682-2 (hydraulic sprayer tests), ISO 22368 (cleaning evaluation), ISO 22369-2 (drift classification), ISO 22866/22856 (drift test methods), ISO 9357 and ISO 13440 (tank and residual volume tests), and ISO 21278 (induction hoppers).
Applications and who uses it
EN ISO 16119-2 is practical for:
- Manufacturers and designers of horizontal boom sprayers to meet environmental performance and regulatory expectations
- Test laboratories and conformity assessors performing verification and field/lab testing
- Regulators and procurement officers specifying environmental requirements for agricultural equipment
- Agricultural advisors and large-scale farmers/operators choosing sprayers with reduced spray drift and better cleaning capabilities
Benefits include clearer design criteria for reducing environmental contamination, standardized test methods for verification, and consistent user instructions to minimize misuse.
