EN 17106-1 explained

EN 17106-1:2021 is a European standard that sets out general safety requirements for road operation machinery.

This standard provides a framework for ensuring that such machinery is designed, manufactured, and used safely throughout its lifecycle. It is the foundational part of the EN 17106 series, with additional parts covering specific machine types.

Scope and Purpose

The standard applies to road operation machinery used for tasks such as cleaning, maintenance, and winter services. It covers safety considerations during the machinery’s entire lifecycle, including:

Transport (both on and off public roads)
Operation (in normal working conditions)
Maintenance (routine servicing and repairs)
Storage (including idle periods between uses)

It does not cover the processes of dismantling, scrapping, or disposal.

What Machinery Does It Cover?

The standard is broad and applies to various machine types, including:

Road Surface Cleaning Machines (e.g., sweepers and suction machines)
Winter Service Equipment (e.g., snow ploughs, grit spreaders)
Grass Cutting and Vegetation Maintenance Machines (for roadside upkeep)
Interchangeable or Mounted Equipment (designed to be attached to vehicles)

It applies regardless of how the machine is powered (self-propelled, towed, or mounted).

Key Safety Requirements

1. General Safety Design Principles

Manufacturers must follow a risk assessment approach to identify hazards and implement appropriate safeguards.

This includes:

Mechanical Safety: Ensuring stability, structural integrity, and protection against moving parts.
Electrical and Hydraulic Systems: Preventing electric shocks, fluid leaks, or pressure failures.
Operator Safety: Providing safe access to controls, reducing exposure to noise and vibration.
Emergency Systems: Including emergency stop functions and fail-safes.

2. Stability and Structural Integrity

The machine must remain stable in all its operating conditions, including:

Stationary operation (when performing maintenance work)
Movement (during transport and work modes)
Sudden stops or emergency conditions

Designs must prevent tipping, overturning, or loss of control.

3. Visibility and Operator Protection

To reduce risks to both operators and bystanders:

Machines must have good visibility (mirrors, cameras, lighting where needed).
Operator cabins must be designed for safety, considering rollover protection (ROPS) or falling object protection (FOPS) where relevant.

4. Noise and Vibration Limits

Excessive noise and vibration can harm operators over time. The standard requires manufacturers to:

Minimise vibration levels transmitted to the driver.
Reduce noise emissions where possible (through insulation, mufflers, or alternative technologies).
Provide warning labels and protective equipment if risks remain.

5. Fire and Chemical Hazards

Machinery must be designed to:

Reduce fire risks from fuel or electrical systems.
Contain and prevent leaks of hydraulic fluids, fuels, or other hazardous substances.
Ensure safe storage and disposal of chemicals (e.g., road treatment agents).

6. Safety of Attachments and Interfaces

Since many machines use interchangeable equipment (e.g., a snow plough fitted to a truck), EN 17106-1:2021 ensures:

Secure attachment mechanisms to prevent detachment during operation.
Safe connection of hydraulic/electrical systems to avoid malfunctions.
Compatibility with different host vehicles, considering safety.

Compliance and Documentation

To comply with EN 17106-1:2021, manufacturers must:

Conduct a Risk Assessment: Identify potential hazards and mitigation strategies.
Provide Clear Operating Instructions: Including manuals, warning labels, and emergency procedures.
Meet EU Machinery Directive Requirements: This standard aligns with EU safety legislation.
Undergo Testing and Verification: Ensuring stability, strength, and performance meet required levels.

Conclusion

EN 17106-1:2021 establishes the fundamental safety principles for road operation machinery. By following its guidelines, manufacturers can create safer, more reliable machines, reducing risks for operators and the public. The standard is part of a broader framework, with additional sections providing more detailed requirements for specific machine types.
