SIST EN ISO 4254-7:2018 PDF

Overview

EN ISO 4254-7:2017 (Corrected version 2019-03) - published by CEN - specifies safety requirements and verification methods for the design and construction of combine harvesters, forage harvesters, cotton harvesters and sugar cane harvesters when used together with ISO 4254‑1. The standard focuses on eliminating or reducing hazards arising from intended use by a single operator during normal operation and service. Where ISO 4254‑7 differs from ISO 4254‑1, its provisions take precedence for machines designed to this part.

Key exclusions: hazards involving people other than the operator, cleaning of the grain tank, vibration and many power‑transmission moving‑part hazards (except strength of guards/barriers), most braking/steering aspects (only ergonomic locations are covered), ROPS design requirements, and safety‑related control system performance levels (ISO 25119 / ISO 13849 are not specified). Road traffic rules and machines manufactured before publication are also outside scope.

Key Topics

The standard addresses practical machine‑safety topics relevant to harvesting equipment, including:

• Operator’s workstation: seat, controls location and identification, steering ergonomics, visibility, warnings, cabins and access.
• Controls & control clearances: start/stop, layout and safe operation.
• Guards and pinching/shearing point protections: folding elements, interchangeable/detachable harvesting devices, header drive and hold‑up.
• Service and maintenance: safe access, supports for raised parts, greasing, electrical/battery safety and operating fluids.
• Grain tank and grain handling systems: tank design and access considerations.
• Noise, fire hazard, hydraulic components and electric equipment: general risk reduction measures.
• Automatic systems: guidance systems and automatic header disengagement controls.
• Annexes include hazard listings and relationship to the EU Machinery Directive (Annex ZA).

Applications

EN ISO 4254-7 is used to:

• Guide manufacturers and designers of harvesting machinery in meeting recognized safety requirements.
• Support risk assessments for combine and forage harvester design and retrofit projects.
• Provide a reference for testing laboratories and conformity assessment bodies when evaluating machine safety against harmonized European requirements.
• Inform safety engineers, purchasers and fleet managers on expected safety features and operator‑focused protections.

Who should use it

• Agricultural machinery manufacturers and OEMs
• Product design and safety engineers
• Certification and conformity assessment bodies
• Maintenance and training teams creating safe work procedures
• Regulators and procurement specialists specifying machine safety requirements

Related standards

• ISO 4254‑1 (general safety requirements) - to be used together with ISO 4254‑7
• References to ISO 25119 and ISO 13849 appear, but EN ISO 4254‑7 does not specify performance levels for safety‑related control systems.
