Overview

EN ISO 4254-14:2016 - Agricultural machinery - Safety - Part 14: Bale wrappers (ISO 4254-14:2016) is a CEN-endorsed type‑C standard that defines safety requirements and verification methods for the design and construction of bale wrappers. It is intended to be used together with ISO 4254‑1 (general requirements). The standard covers mounted, semi‑mounted, trailed and certain stationary bale wrappers (including units combined with pick‑up balers), and provides guidance to eliminate or reduce hazards during normal use and reasonably foreseeable misuse by a single operator.

Key topics and requirements

• Scope & applicability
  • Applies to mounted, semi‑mounted, trailed and some stationary bale wrappers; explicitly excludes non‑mobile fixed wrappers, tube/inline wrappers, certain in‑chamber wrapping processes, and several other specific items (see standard for full exclusions).
• Hazard analysis
  • Lists significant hazards relevant to bale wrappers (see Table 1 in the standard) and addresses hazardous situations and events.
• Controls and ergonomics
  • Requirements for operator controls, remote controls (wired and wireless), machine stop controls, and reliability of control systems.
• Automatic operation
  • Safety requirements for machines with automatic modes of operation.
• Loading/unloading & stability
  • Visibility, bale handling, unloading procedures and stability of tractor‑wrapper combinations; annexes include stability and loading test details.
• Maintenance & adjustments
  • Safe procedures for maintenance tasks such as replacement and collection of plastic wrap/film.
• Wrapping systems
  • Safety for stretching systems, rotating platforms, stopping devices and wrap/film cutting devices; includes test methods for pressure‑sensitive sensor arms.
• Noise
  • Noise reduction measures and verification of noise emission values.
• Verification & information
  • Test/verification methods, operator’s manual content, marking, instructional and safety signs.
• Normative and informative annexes
  • Examples of wrapper types (Annex A), stability computation (Annex B), loading stability tests (Annex C), sensor arm test methods (Annex D).

Applications - who uses this standard

• Manufacturers and designers of mounted, trailed and semi‑mounted bale wrappers to ensure safe product design and CE conformity.
• Safety engineers and test laboratories performing verification and validation against ISO 4254‑14 requirements.
• Regulatory and conformity assessment bodies using the standard to demonstrate compliance with EU Directive 2006/42/EC.
• Farm equipment procurement and maintenance teams for understanding operator safety, marking and manual requirements.

Related standards

• ISO 4254‑1 (General requirements) - to be used together with Part 14; where conflicts occur, Part 14 takes precedence for covered machines.
• ISO 4254‑11 - requirements for pick‑up balers (relevant for combined units).
