EN ISO 4254-5:2018 PDF

Overview

EN ISO 4254-5:2018 (ISO 4254-5:2018) - "Agricultural machinery - Safety - Part 5: Power-driven soil-working machines" is a Type‑C standard published by CEN/ISO. Intended to be used together with ISO 4254‑1, it specifies safety requirements and verification for the design and construction of mounted, semi‑mounted and trailed power‑driven soil‑working machines used in agriculture. It also defines what information manufacturers must supply on safe working practices, including residual risks.

The standard addresses significant hazards listed in Annex A and includes informative Annexes with examples of machines and hazard relationships. It is not applicable to spading machines, machines with retractable devices for working between plants, environmental hazards, or most power‑transmission moving‑part hazards (except strength requirements for guards and barriers).

Key topics and requirements

• Scope & applicability: Clear definition of machine types covered (mounted, semi‑mounted, trailed) and exclusions (spading machines, certain retractable devices, pre‑publication machines).
• Safety requirements and risk reduction: Design and construction measures to reduce significant hazards relevant to soil‑working tools.
• Verification: Procedures to verify that safety requirements and protective measures are implemented and effective.
• Protection of working tools: Measures against inadvertent contact with power‑driven tools and protection from thrown objects.
• Noise reduction: Added requirements addressing noise as a safety concern.
• Control and adjustment: Requirements on location and operation of working‑depth and other controls.
• Information for use: Mandatory content for the operator’s manual, safety/instructional signs and documentation of residual risks.
• Annexes: Annex A lists significant hazards; Annex B gives examples of power‑driven soil‑working machines.

Practical applications

• Design and development of ploughs, cultivators, harrows and other power‑driven soil‑working implements to meet recognized safety benchmarks.
• Preparing technical documentation, operator manuals and safety labels required for safe use and market entry.
• Conducting risk assessments, verification testing and CE conformity demonstrations (the standard supports conformity with Directive 2006/42/EC where cited).
• Supporting procurement and market surveillance decisions by regulators and safety bodies.

Who should use this standard

• Machine manufacturers (R&D, design, compliance teams)
• Regulators and certification bodies (market surveillance, conformity assessment)
• OEMs and agricultural equipment suppliers
• Health & safety professionals, risk assessors and maintenance planners
• Service providers involved in safe installation and instructions for users

Related standards

• ISO 4254‑1 - General safety requirements for agricultural machines (EN ISO 4254‑5 is intended to be used together with ISO 4254‑1; where conflicts exist, EN ISO 4254‑5 takes precedence for covered machines).
• Other parts of the ISO 4254 series covering different groups of agricultural machinery.
