Overview

EN 1870-4:2001/prA1 (CEN) is a draft amendment to the European safety standard for multiblade rip sawing machines with manual loading and/or unloading. It updates EN 1870-4:2001 to clarify scope, normative references and safety requirements for machines used to cut solid wood, chipboard, fibreboard, plywood and similar panel materials (including those with plastic edging or laminates). The amendment aligns the standard with newer EN/ISO safety standards and references the EU Machinery Directive (see Annexes ZA and ZB).

Key topics and technical requirements

The amendment revises and supplements the original standard across multiple clauses. Major technical topics include:

• Scope and definitions - clarifies the types of machines and materials covered (multiblade rip sawing machines; manual loading/unloading).
• List of significant hazards - a structured table of mechanical, electrical, noise, radiation, dust/materials, ergonomic and control-system hazards to be addressed by risk assessment.
• Safety of control systems - requirements for reliability, failure modes, start/stop behaviour and protection against unexpected restart (references to EN ISO 12100 and EN ISO 13849-1).
• Start, normal stop, emergency stop and power-failure behaviour - incorporation of principles from EN ISO 13850 and related electrical safety standards (EN 60204‑1).
• Guarding and tool protection - requirements for tool guards, anti‑kickback devices and measures to reduce ejection, kickback and break-up risks.
• Ergonomics, handling and human factors - guidance on controls, displays and operator interaction to reduce human error and physical strain.
• Noise, dust and laser/radiation hazards - identification and mitigation measures for hearing risk, airborne dust/contaminants and laser emissions where applicable.
• Information for use - marking, instructions and documentation obligations for manufacturers and suppliers.

Practical applications and users

Who uses EN 1870-4/prA1 and why:

• Machine designers and manufacturers - to design compliant multiblade rip sawing machines and update technical documentation.
• Safety and compliance engineers - for risk assessments, CE conformity and applying the Machinery Directive requirements.
• Factory managers, purchasers and integrators - to specify safe machines and select appropriate guarding, stops and control-system solutions.
• Maintenance and training personnel - to follow safe work, maintenance and instruction handbook requirements.
• Test laboratories and notified bodies - to assess conformity against updated normative references.

Related standards (examples referenced)

• EN ISO 12100-1 / -2 (machine safety - design and risk assessment)
• EN ISO 13849-1 (safety-related parts of control systems)
• EN ISO 13850 (emergency stop)
• EN ISO 13857 (safety distances)
• EN 60204-1 (electrical equipment)
• EN 1760-2 (pressure sensitive protection)
• EN 60825-1 (laser safety)
• EN 847-1 (woodworking tools safety)
