EN ISO 19085-14:2021 PDF

Overview

EN ISO 19085-14:2021 - "Woodworking machines - Safety - Part 14: Four-sided moulding machines" (CEN adoption of ISO 19085-14:2021) specifies safety requirements for four-sided moulding machines used in continuous production. The standard covers machines designed to cut solid wood and materials with similar physical characteristics, with a maximum working width of 350 mm and an integrated feed speed up to 200 m/min. It addresses hazards during normal use, reasonably foreseeable misuse, and lifecycle phases including transport, assembly, dismantling, disabling and scrapping.

This European adoption supersedes EN 12750:2013 and provides a harmonized means to show conformity with the EU Machinery Directive (see Annex ZA).

Key topics and technical requirements

The standard focuses on practical machine safety and contains requirements across control, mechanical protection and information:

• Control systems and devices

  • Safety and reliability of control systems
  • Start and safe-stop functions (normal stop, operational stop, emergency stop)
  • Mode selection (including work and service modes), manual reset and tele-service considerations
  • Power failure behaviour and standstill detection
  • Time delay and speed monitoring functions

• Tooling, spindles and drives

  • Tool and tool-fixing design, spindle locking and flange requirements
  • Braking of tools and maximum run-down time requirements
  • Tool speed changing methods (belt shifts, variable speed drives, frequency inverters) and spindle rotation direction controls

• Mechanical hazards and protection

  • Machine stability and risk of break-up during operation
  • Fixed guards and interlocking movable guards, safeguarding against ejection and accidental contact
  • Specific handling of hazards from added units (e.g., universal spindle, glass bead saw unit, quick tool changers, laser marking units, in-feed hopper, loading magazine, unloading table)

• Scope exclusions

  • Certain in-feed/out-feed devices (beyond in-feed hopper/loading magazine and unloading table), machines used in explosion-risk atmospheres, machines manufactured before publication, and machines in combined production lines are excluded or have limits noted (e.g., feed speeds >60 m/min require special consideration).

Applications and users

Who benefits from EN ISO 19085-14:

• Machine manufacturers designing four-sided moulders to meet safety and regulatory requirements
• Safety engineers and compliance teams performing risk assessments and CE conformity checks
• Plant managers and procurement specifying safe machinery for production lines
• Maintenance and service personnel applying safe isolation, guarding and locking procedures
• Notified bodies and testing laboratories assessing conformity with the Machinery Directive
