ISO 16119-2:2013

Overview

ISO 16119-2:2013 - Agricultural and forestry machinery - Environmental requirements for sprayers - Part 2: Horizontal boom sprayers specifies environmental design and verification requirements for horizontal boom and similar low‑crop sprayers. Intended to be used together with ISO 16119-1 (general requirements), this part focuses on reducing environmental contamination during normal use and foreseeable misuse. It does not cover machine safety (see ISO 4254-6) and is not applicable to sprayers manufactured before its publication.

Key topics and technical requirements

The standard sets measurable requirements and references established test methods (e.g., ISO 5682 series). Major technical topics include:

• Spray tank design

  • Inner/outer surface roughness limit: Rz ≤ 100 µm (ISO 4287/4288).
  • Filling devices designed to avoid return to supply; filling hole sizes per ISO 9357.
  • Strainers: mesh size < 2 mm, minimum depths specified by tank capacity.
  • Filling capacity: for tanks ≥ 100 L, strainer-equipped filling must allow ≥ 100 L/min; smaller tanks must be fillable within 1 minute.
  • Mixing/agitation to ensure concentration uniformity (allowed deviation ±15% per ISO 5682-2).
  • Residual volume limit: total residual ≤ 0.5% of nominal tank volume + 2 L per metre of boom (ISO 13440).
  • Tank emptying devices and guarded outlets to enable complete drainage without environmental contamination.

• Hoses, lines and valves

  • Hoses must respect manufacturer bending radii and be free of deformations; pressure lines need quick-acting shut-off valves.

• Spray boom

  • Working section width limits and independent section use; boom height adjustment ranges (minimum ranges given, e.g., at least 1.0 m, and 1.2 m for crops >1.0 m).
  • Ability to adjust nozzle-to-target distance (down to 0.5 m in most cases).
  • Measures to prevent spraying on the sprayer itself.

• Nozzles, filters and measuring systems

  • Requirements for nozzle selection, distribution and drift control; filtration and measuring systems to support accurate application rates.

• Marking and documentation

  • Marking and instruction handbook requirements to support correct use and environmental protection.

Practical applications and users

ISO 16119-2:2013 is used by:

• Agricultural machinery manufacturers and design engineers for compliant sprayer design.
• Test laboratories and certification bodies for type testing and verification.
• Procurement specialists and farm managers specifying low‑drift, environmentally compliant sprayers.
• Regulators and compliance teams aligning equipment with environmental protection requirements.

Benefits include reduced off‑target contamination, clearer procurement specifications, and documented verification methods for environmental performance.
