Overview

oSIST prEN ISO 19085-3:2026:2026 specifies the safety requirements and protective measures for numerically controlled (NC/CNC) boring and routing machines used in woodworking and similar applications. Developed by CEN and aligned with ISO standards, this draft international standard addresses machines capable of continuous production use. It focuses on mitigating significant hazards throughout all operational phases, including transport, assembly, operation, adjustment, maintenance, dismantling, disabling, and scrapping.

This document covers a broad category of NC/CNC equipment-including machines fitted with additional working units for sawing, sanding, assembling, dowel inserting, fixed or movable workpiece supports, mechanical/pneumatic/hydraulic/vacuum clamping, automatic tool changers, and edge-banding units. It applies to machines processing materials such as solid wood, engineered composites, mineral boards, light alloy profiles, and various synthetic materials.

Key Topics

Safety Requirements for NC/CNC Woodworking Machines

• Scope of Machines: Definitions and distinctions for NC/CNC boring, routing, or combined boring and routing machines, with programming of at least two orthogonal axes (e.g., X, Y).

• Operational Phases: Safety measures for intended operation, foreseeable misuse, set-up, maintenance, and decommissioning.

• Integrated Units: Coverage of machines equipped with supplementary devices for enhanced functionality (e.g., edge banding, additional working units).

• Hazard Coverage: Identification and mitigation of risks such as mechanical hazards, electrical hazards, dust and chip emission, fire, noise, ergonomics, and others.

• Protective Measures:

  • Reliable control systems, including emergency stops and reset devices
  • Tool and spindle design, speed control, and braking functions
  • Guards (fixed, interlocking), safeguarding around loading/unloading zones, and access prevention
  • Workpiece clamping safety (mechanical, pneumatic, hydraulic)
  • Impact and ejection prevention
  • Maintenance and information for user safety

• Limitations:

  • Excludes hazards from grinding wheels, certain large cutting tools, and non-compliant sawing tools
  • Does not address integrated machine lines or robotic loading/unloading systems
  • Not applicable to single spindle hand-fed routers or machines for potentially explosive atmospheres

Applications

oSIST prEN ISO 19085-3:2026 is practical for a wide range of stakeholders in the woodworking machinery sector:

• Manufacturers and Designers: Essential for developing, certifying, and improving NC/CNC boring and routing machines in compliance with international safety norms.
• Industrial Users: Supports safe operation, adjustment, and maintenance procedures for continuous production environments.
• Health and Safety Bodies: Provides a reference for regulatory compliance, accident prevention, and risk assessment in woodworking operations.
• Service Providers and Maintenance Teams: Supplies guidelines for safe disassembly, installation, maintenance, and scrapping of machinery.

Industries benefiting from compliance include furniture manufacturing, cabinetmaking, interior design components, and panel board production. The standard helps reduce workplace injuries, enhance machine reliability, and ensure operational continuity.

Related Standards

For holistic safety and technical conformity, oSIST prEN ISO 19085-3:2026 should be used alongside other key standards, such as:

• ISO 19085-1:2026 - Common safety requirements for woodworking machines
• ISO 12100:2010 - General principles for design and risk assessment in machinery safety
• ISO 13849-1:2023 - Safety-related parts of control systems
• EN 847-1:2017 & EN 847-2:2017 - Safety requirements for woodworking tooling
• IEC 60204-1:2016 - Electrical equipment safety for machinery
• ISO 19085-17 - Guidance for edge-banding equipment risk assessment

Note: Edge-banding equipment hazards should be assessed using ISO 19085-17 for comprehensive coverage.

---

Implementing oSIST prEN ISO 19085-3:2026 ensures that modern woodworking operations using NC/CNC boring and routing technology meet the highest levels of safety, operational efficiency, and regulatory compliance. Adherence to this standard demonstrates a commitment to responsible production and worker protection within the woodworking industry.

This document deals with all significant hazards, hazardous situations or hazardous events, listed in
Annex A, relevant to the machines when used as intended and under conditions of misuse which are
reasonably foreseeable. Also, transport, assembly, adjustment, maintenance, dismantling, disabling and
scrapping phases have been taken into account.
This document is also applicable to machines fitted with one or more of the following devices or additional
working units, whose hazards have been dealt with:

ISO/DIS 19085-3:2026(en)
The mode selection switch shall be located outside the hazard zone, e.g. on the main control panel, or close
to the disabled safeguard giving access to the hazard zone, and shall not be possible to actuate it from inside
the hazard zone.
Hold-to-run control devices and enabling control devices for tool or axes movements shall be located on the
main control panel or on a hand-held set of controls connected to the machine by cable or wireless, or on
both;
An emergency stop control device shall be provided at each working station and, in particular, at each of the
following positions:
a) at the main control panel;
b) at the hand-held control set;
c) adjacent to all hold-to-run control devices;
d) adjacent to all cycle start control devices;
e) at the workpiece loading and unloading station;
f) inside any enclosure fitted with access door required in 5.6.2;
g) close to or inside any tool magazine separated from the machining area and energized during loading

a protective device shall be either a normal stop or an operational stop or an emergency stop.
If the machine is divided into physically separated danger zones, actuators to be stopped may be only those
of the relevant danger zone. In this case, a local manual reset control device is required.
