ISO 4254-14:2016

Overview

ISO 4254-14:2016 - "Agricultural machinery - Safety - Part 14: Bale wrappers" is a type-C international standard that specifies safety requirements and verification for the design and construction of mounted, semi‑mounted, trailed, and stationary bale wrappers (including wrappers combined or integrated with pick‑up balers). It is intended to be used together with ISO 4254‑1 (general requirements). The standard addresses hazards from intended use and reasonably foreseeable misuse by a single operator during normal operation and service. It also defines required manufacturer information on safe working practices.

The standard explicitly excludes non-mobile fixed wrappers, tube/inline wrappers, certain wrapping-in-chamber processes, some control-system performance-level specifications, and most environmental and road-safety hazards (noise is included).

Key topics and technical requirements

ISO 4254-14:2016 covers practical safety topics and verifiable measures, including:

• Controls and interfaces: general control layout, remote controls (cabled and cableless), machine stop controls, and reliability requirements.
• Automatic operation: requirements for machines with automatic modes.
• Loading and unloading: visibility, loading/unloading system design and stability considerations.
• Maintenance and adjustments: safe procedures for replacing plastic wrap/film and collecting residue wrap/film.
• Stretching system and wrapping arm: design and stopping devices for stretch rolls and requirements for rotating platforms.
• Wrap/film cutting device: safety measures for cutting systems.
• Noise: reduction measures and verification based on noise emission values.
• Verification and testing: methods to verify safety requirements, including annexed test methods (e.g., sensor arm pressure-sensitive device tests in Annex D).
• Information for use: operator’s manual content, markings, instructional and safety signs (aligned with ISO 3600 and ISO 3864 series).

Applications and who uses it

ISO 4254-14:2016 is applicable to:

• Manufacturers and designers of bale wrappers (mounted, semi‑mounted, trailed, stationary).
• Product safety and compliance engineers implementing machine safety design and documentation.
• Test laboratories and certification bodies verifying conformity with ISO safety criteria.
• Purchasers, farm managers, and fleet operators seeking safer bale wrapping equipment and clear manufacturer instructions.
• Regulatory agencies referencing international safety requirements for agricultural machinery.

Using ISO 4254-14 helps reduce operator risk, improves machine usability, and supports compliance with international best practices for agricultural machinery safety.
