ISO 19085-4:2024 PDF

Overview

ISO 19085-4:2024 - "Woodworking machines - Safety - Part 4: Vertical panel circular sawing machines" specifies safety requirements and protective measures for manually loaded/unloaded vertical panel circular sawing machines intended for continuous production. The standard covers hazards during normal operation, adjustment, maintenance and reasonably foreseeable misuse, and it also addresses transport, assembly, dismantling and scrapping. Machines fitted with common accessories (integrated feed, scoring, angle cutting, middle support, programmable end stops, small grooving tools ≤27 mm cutting width, panel pushers/lowers, horizontal cut stops) are included. The document excludes certain machine types (for example, machines with pressure beam behind the support, vertically fixed guide rails requiring manual feed for horizontal cuts, purely vertical cutters, multi-cycle automatic machines, machines for explosive atmospheres, and pre‑publication machines).

Key topics and technical requirements

• Control systems and safety functions: reliability of controls, start/stop modes (direct, power-on start), safe stops, emergency stop, braking functions and standstill detection.
• Mechanical protection: tool and spindle design, flange dimensions, spindle locking, braking performance, run‑down time and brake release.
• Safeguarding and access prevention: fixed and interlocking movable guards, hold-to-run and two‑hand controls, enabling devices, electro-sensitive and pressure-sensitive protective equipment (ESPE, PSPE), anti‑kickback and ejection prevention.
• Workpiece handling: workpiece supports, middle support devices, angle cutting and panel pushing/ lowering devices.
• Other hazards: noise control and measurement, emission of chips and dust, fire, electricity, ergonomics, lighting, pneumatics/hydraulics, EMC, static electricity and maintenance requirements.
• Verification and tests: normative and informative annexes include stability tests, braking function tests and impact tests for guards, plus a list of significant hazards and required performance levels.

Practical applications - who uses this standard

• Machine manufacturers and designers - to design and certify vertical panel circular sawing machines that meet international safety expectations.
• Safety and compliance engineers - for CE/market conformity, risk assessments and functional safety verification.
• Plant managers and purchasers - to specify safe machine features and select compliant equipment for production lines.
• Maintenance teams and trainers - to implement safe maintenance procedures, operator training and instruction handbooks.
• Test laboratories and notified bodies - to perform required tests (stability, braking, guard impact) and assess conformity.

Related standards

• ISO 19085-1:2021 (terminology and general requirements for woodworking machines) and other parts of the ISO 19085 series are relevant for broader machine safety context and harmonized terminology.
