Overview

EN 1870-5:2002/prA1 is a European standard focusing on the safety of woodworking machines, specifically addressing circular sawing machines, including circular sawbenches and up-cutting cross-cut sawing machines. Developed under the authority of CEN’s Technical Committee CEN/TC 142 “Woodworking machines - Safety,” this standard provides essential safety requirements and risk reduction measures for machines designed to cut solid wood, chipboard, fibreboard, plywood, and similar laminated materials.

This amendment aims to enhance safety by updating definitions, safety requirements, control systems, and hazard identification for these types of woodworking machines. It aligns with directives such as the EU Machinery Directive 2006/42/EC, making it essential for manufacturers, operators, and safety professionals involved in woodworking machinery applications.

Key Topics

• Scope and Definitions
  EN 1870-5:2002/prA1 clarifies the scope by specifying the types of machines covered, notably circular sawbenches and up-cutting cross-cut sawing machines used in stationary setups. It distinguishes these from hand-held motor-operated tools, transportable tools, and machines adapted for bench mounting.

• Hazard Identification and Risk Assessment
  The standard includes an exhaustive list of significant hazards associated with circular sawing machines. Key mechanical and electrical hazards are identified with references to risk assessment standards such as EN ISO 12100. Notable hazards include crushing, shearing, cutting, entanglement, electrical contact, noise exposure, vibration, and risks from fire and explosion.

• Safety Requirements and Control Systems
  Updated safety requirements emphasize reliability in control systems, safe starting and stopping procedures, and power supply failure management. It also covers mechanical integrity including spindle locking, prevention of ejection of workpieces, and ergonomic design to reduce operator strain and error.

• Ergonomics and Human-Machine Interaction
  This standard stresses the importance of ergonomic principles in machine design to prevent unhealthy postures, handling difficulties, and human errors. It mandates proper design and location of manual controls and visual displays for optimal user interaction.

• Information and Marking
  The document outlines requirements for machine marking and instruction handbooks, ensuring that operators receive essential information about safe use and maintenance.

Applications

EN 1870-5:2002/prA1 is pivotal for any entity involved in the manufacture, installation, and operation of circular sawing machines in woodworking environments, including:

• Woodworking Facilities that utilize sawbenches and cross-cut sawing machines to safely and efficiently process wood and wood-based materials.
• Machine Manufacturers seeking compliance with European safety regulations to design and produce machines that minimize operator risks.
• Safety Inspectors and Compliance Officers responsible for auditing woodworking machinery operations to ensure adherence to safety standards.
• Workplace Safety Professionals focused on developing ergonomic, reliable, and safe machine interfaces and environments.
• Training Providers educating operators on the risks and safe handling practices for circular sawing machines.

Implementing this standard helps reduce injury risks, improve operational safety, and comply with legal and regulatory requirements.

Related Standards

For a comprehensive safety framework, EN 1870-5:2002/prA1 references and complements several key standards, including:

• EN ISO 12100 – General principles of risk assessment and machine safety design.
• EN ISO 13849-1 – Safety-related parts of control systems.
• EN ISO 13857 – Safety distances to prevent hazard zones being reached by upper and lower limbs.
• EN ISO 3745, EN ISO 3746, EN ISO 11202 – Standards related to sound power levels and noise measurements.
• EN 614-1, EN 894 series – Ergonomic design principles and requirements.
• EN 1005 series – Human physical performance and machine interaction.
• EN 60204-1 – Electrical equipment of machines.
• EN 60825-1 – Safety of laser products (if applicable).
• EN 60745 series – For motor-operated hand tools used in combination with machines.

Adherence to this suite of standards ensures a holistic approach to safety in woodworking operations, covering mechanical, electrical, ergonomic, and environmental factors comprehensively.
