Overview

SIST EN 1870-12:2004/kprA1:2009 is a European standard developed by CEN (the European Committee for Standardization) focused on the safety of woodworking machines, specifically circular sawing machines. Part 12 of this standard addresses the requirements and safety modifications relevant to pendulum cross-cut sawing machines designed to cut solid wood and engineered wood products such as chipboard, fibreboard, and plywood, including materials with plastic or light alloy laminates.

This standard is a draft amendment aimed at updating safety requirements and aligning the existing EN 1870-12:2003 standard with the latest regulations and technical principles. It highlights significant hazards, prescribes safety measures, and clarifies compliance with European directives, particularly the Machinery Directive 2006/42/EC.

Key Topics

• Scope and Definitions
  The document focuses on hazards associated with pendulum cross-cut saws used in woodworking, redefining key concepts such as "displaceable machine" and "information from the supplier" to ensure clarity in safety application.

• Hazard Identification
  It provides a comprehensive list of significant hazards including:

  • Mechanical hazards like crushing, shearing, cutting, entanglement, and impact risks
  • Electrical hazards involving direct and indirect contact with live parts, electrostatic phenomena
  • Noise hazards causing hearing loss and communication interference
  • Radiation hazards, including laser safety
  • Exposure to harmful dusts, fluids, and fire risks
  • Ergonomic concerns like unhealthy postures, excessive effort, manual handling, and human error

• Safety Requirements
  Updated clauses address controls for:

  • Safety and reliability of control systems
  • Starting procedures for manual, semi-automatic, and automatic machines
  • Emergency stop functionality according to EN ISO 13850 standards
  • Power supply and control circuit failure management
  • Machine stability and risk of break-up during operation
  • Marking, labeling, and instruction handbook requirements for safe use

• Normative References
  The amendment replaces and updates numerous normative references to the latest international standards, including:

  • EN ISO 12100 (Safety of machinery – design principles)
  • EN ISO 13849 (Safety-related parts of control systems)
  • EN ISO 13857 (Safety distances for hazard zones)
  • EN ISO 13850 (Emergency stop principles)
  • EN 60825-1 (Safety of laser products)
    These references ensure the holistic integration of current safety technologies and ergonomic best practices.

Applications

• Woodworking Industry
  SIST EN 1870-12:2004/kprA1:2009 is essential for manufacturers, operators, and safety inspectors involved with pendulum cross-cut sawing machines. It guides machine design, operation protocols, and maintenance to minimize injury risks in wood processing workplaces.

• Machine Design and Manufacturing
  Machine builders use this standard to incorporate safety features consistent with EU directives, ensuring their equipment is market-ready across European countries and meets legal safety obligations.

• Workplace Safety Compliance
  Facilities with woodworking operations can apply this standard to assess risk levels, implement protective measures, and ensure employee safety by complying with recommended procedures and emergency response protocols.

Related Standards

• EN ISO 12100:2003 – Basic concepts and design principles for machinery safety
• EN ISO 13849-1:2008 – Safety-related parts of control systems
• EN ISO 13850:2006 – Emergency stop principles
• EN ISO 13857:2008 – Safety distances to prevent access to hazardous zones
• EN 60825-1:2007 – Safety requirements for laser products
• EN 60204-1:2006 – Electrical equipment of machines – safety requirements

In addition, the standard references ergonomic guidelines (EN 894 series), electromagnetic compatibility (EMC) standards (EN 50370), and low-voltage switchgear standards (EN 60947 series), ensuring a comprehensive safety framework for woodworking machinery.
