ISO 19085-4:2018

Overview

ISO 19085-4:2018 - Woodworking machines - Safety - Part 4: Vertical panel circular sawing machines - specifies safety requirements and measures for manually loaded and unloaded stationary vertical panel sawing machines. The standard addresses significant hazards during intended use and reasonably foreseeable misuse across all lifecycle phases including transport, assembly, operation, maintenance, dismantling and scrapping. It also covers machines fitted with common additional units (feed devices, scoring, angle cutting, middle supports, programmable stops, small grooving tools, panel pushers) and defines specific exclusions.

Keywords: ISO 19085-4:2018, vertical panel circular sawing machines, woodworking machine safety.

Key topics and technical requirements

ISO 19085-4:2018 organizes requirements to reduce mechanical and other hazards. Major technical topics include:

• Control system safety: reliability, start/stop functions, emergency stop, safe stops, mode selection, spindle speed changing and failure-of-power measures.
• Braking and spindle requirements: braking functions, maximum run-down times and test procedures (Annex B).
• Guarding and access prevention: fixed and interlocking guards, hold-to-run and two‑hand controls, electro- and pressure-sensitive protective equipment, guarding of tools, drives, shearing/crushing zones, impact testing for guards (Annex D).
• Work-piece support and feeding: design and stability of supports, middle support device, angle cutting attachments and anti-kickback/anti-ejection measures.
• Mechanical integrity and stability: tool holder design, flange dimensions, risk of break-up, stability tests for displaceable machines (Annex C).
• Other hazards: noise and dust/chip emissions (noise measurement guidance in Annex E), fire, electrical, ergonomics, lighting, pneumatics/hydraulics, EMC, static electricity and maintenance requirements.
• Information for use: markings, warning devices and operator instructions.

Practical applications and who uses it

ISO 19085-4 is intended for anyone involved in the design, manufacture, selection, installation, testing, maintenance and inspection of vertical panel circular sawing machines:

• Machine manufacturers and designers ensuring conformity with safety requirements
• Safety engineers and compliance officers preparing CE documentation or risk assessments
• Plant managers and procurement specialists selecting safe woodworking equipment
• Maintenance technicians and trainers using operator instructions and test procedures
• Certification bodies and test labs conducting braking, stability, impact and noise tests
