EN ISO 4254-6:2020 PDF

Overview

EN ISO 4254-6:2020 - Agricultural machinery - Safety - Part 6: Sprayers and liquid fertilizer distributors (ISO 4254-6:2020) is a CEN-adopted international standard that specifies safety requirements and verification for the design and construction of mounted, semi‑mounted, trailed and self‑propelled agricultural sprayers and liquid fertilizer distributors intended for a single operator. It is to be used together with ISO 4254‑1. The standard applies to machines placed on the market after its publication (2020) and replaces the 2009 edition.

Key topics and requirements

• Scope of application: mounted, semi‑mounted, trailed and self‑propelled sprayers and liquid fertilizer distributors designed for a single operator. Not applicable to machines manufactured before publication.
• Use with ISO 4254‑1: where EN ISO 4254‑6 differs from ISO 4254‑1, this part takes precedence for machines designed according to it.
• Safety requirements and verification: covers significant hazards, hazardous situations and events foreseeable by the manufacturer when machines are used as intended (see Annex A).
• Manufacturer information: specifies the type and content of information on safe working practices, including warnings of residual risks and instructions for use.
• Design and construction elements highlighted:
  • Requirements for chemical induction bowls (amended to include foldable devices)
  • Provisions addressing leakages and protecting the operator from exposures from leaks
  • Storage requirements for personal protective equipment (PPE)
  • Alignment of Clause 6 (information and marking) with ISO 4254‑1
• Excluded or separately covered hazards: operator protection from spray during active spraying (addressed by EN 15695), automatically actuated height adjustment systems, environmental hazards other than noise, and moving power transmission parts except for strength requirements of guards/barriers.

Practical applications

• Manufacturers and OEMs: design and certify new sprayers and liquid fertilizer distributors to meet harmonized safety expectations.
• Product designers and R&D teams: use the technical requirements to integrate safety measures (PPE storage, leak mitigation, induction device design).
• Conformity assessors and test laboratories: verify compliance and prepare documentation for market access.
• Safety managers and agricultural contractors: reference required operator information, warnings and maintenance/servicing guidance.
• Regulators and procurement teams: use the standard as a benchmark for specifying safe equipment that aligns with EU Machinery Directive 2006/42/EC (Annex ZA correspondence provided).

Related standards

• ISO 4254‑1 - General safety requirements for agricultural machinery (use together with EN ISO 4254‑6)
• EN 15695 - Protection of the operator against hazardous substances (cabs and filters) - relevant for spray exposure
• EU Machinery Directive 2006/42/EC - EN ISO 4254‑6 includes Annex ZA to show relationships to essential requirements

EN ISO 4254‑6:2020 is essential for anyone involved in the safe design, manufacture, testing or procurement of agricultural sprayers and liquid fertilizer distributors seeking compliance with contemporary European and international safety expectations.
