ISO 19085-3:2021

Overview

ISO 19085-3:2021 - "Woodworking machines - Safety - Part 3: Numerically controlled (NC/CNC) boring and routing machines" defines safety requirements for NC/CNC boring, routing and combined boring/routing machines intended for continuous production. The standard covers machine lifecycle phases including operation, adjustment, maintenance, transport, assembly, dismantling and scrapping, and addresses reasonably foreseeable misuse. It applies to machines with additional units (sawing, sanding, automatic tool change, clamping, workpiece supports) and to edge-banding equipment (with risk-assessment guidance referenced). The standard lists materials the machines are designed to process (solid wood, wood-like materials, gypsum boards, composite materials, aluminium light alloy profiles/plates up to 10 mm, etc.) and specifies hazards that are excluded.

Key topics and technical requirements

ISO 19085-3 organizes safety measures across control systems, mechanical hazards and auxiliary risks. Major technical topics include:

• Control system safety and reliability: requirements for control architecture, safe starts/stops, mode selection (machine setting, clamping positioning, tool positioning), manual reset and tele-service considerations.
• Stop and braking functions: definitions and requirements for normal, operational and emergency stop, tool braking and maximum run-down times.
• Guarding and access prevention: fixed guards, interlocked movable guards, hold-to-run, two-hand controls, enabling controls, electro-sensitive protective equipment (ESPE) and pressure-sensitive protective equipment (PSPE).
• Risk of ejection and impact: requirements for guards, curtains, materials, and minimum clearances at loading/unloading zones.
• Tooling, spindles and clamping: safe tool fixing, spindle locking and clamping devices.
• Noise, dust and emissions: design measures to reduce noise, dust/chip emission controls and requirements for measurement/declaration.
• Electrical, pneumatic, hydraulic and EMC safety: relevant design and maintenance considerations.
• Information for use: marking, warning devices and instruction handbook content.
• Testing and verification: normative annexes include stability, braking, impact and noise tests and performance levels (Annex B).

Practical applications - who uses this standard

ISO 19085-3 is used by:

• Machine designers and manufacturers to engineer safe NC/CNC boring and routing machines.
• Safety engineers and compliance teams conducting risk assessments and preparing conformity documentation.
• Quality and test laboratories performing stability, braking, impact and noise tests listed in the annexes.
• Integrators and OEMs selecting and combining additional working units (automatic tool changers, clamping systems).
• Maintenance teams and operators for safe operation, servicing and instructions.

Practical benefits include guiding safeguard selection (guards, ESPE/PSPE), control system design for safe modes and stops, reducing noise/dust emissions, and documenting safety measures for regulatory compliance and CE marking.
