Electric motor-operated tools - Dust measurement procedure - Part 2-5: Particular requirements for circular saws

This European Standard specifies general requirements for the dust measurement of electric motor-operated tools supplied from mains or from batteries. This European Standard applies to those tools with and without dust extraction unit where dust such as mineral dust containing silica or wood dust is expected. This part of EN 50632 sets particular requirements for circular saws.

Overview

EN 50632-2-5:2016/A1:2021 is a European Standard developed by CLC that addresses the dust measurement procedure specifically for electric motor-operated circular saws. This standard is part of the broader EN 50632 series, which covers dust measurement for various electric tools powered by mains or batteries. Applicable to tools with or without dust extraction units, it targets scenarios where hazardous dust-such as mineral dust containing silica or wood dust-is generated during operation. The amendment A1 released in 2021 introduces important updates based on practical testing, enhancing the clarity and effectiveness of dust measurement for circular saws.

Key Topics

• Scope and Application
  EN 50632-2-5 defines particular requirements for testing dust emissions from circular saws used in woodworking and similar tasks. It complements the general dust measurement procedures outlined in EN 50632-1 and its amendments.

• Test Setup and Conditions
  The standard specifies precise operating conditions for dust measurement tests, including:

  • Use of chipboard material (P2 classification, density: 610 ± 60 kg/m³, thickness: 19 ± 1 mm)
  • Horizontal mounting of the workpiece on a bench aligned with dust sampler intakes
  • Cutting of approximately 10 mm wide strips across a length of 400 mm
  • Proper orientation of the operator relative to the saw, detailed in Figure 101
  • Use of manufacturer-specified new saw blades designed for chipboard cutting
  • Speed and feed settings ensuring stable and reproducible operation
  • Performance of at least 30 cuts per test cycle over about 10 minutes or longer as needed

• Operator and Tool Orientation
  The standard provides a clear layout (Figure 101) illustrating the orientation of the workpiece, circular saw, and operator during testing. This ensures consistency, safety, and reliable dust measurement outcomes for right-handed and left-handed tools.

• Safety and Environmental Considerations
  By defining robust dust measurement procedures, EN 50632-2-5 supports the reduction of harmful dust exposure in workplaces, aligning with occupational health and safety regulations for controlling respirable dust hazards.

Applications

EN 50632-2-5:2016/A1:2021 is invaluable for:

• Manufacturers of Circular Saws
  To verify and validate the dust emission performance of their tools under standardized test conditions prior to market release.

• Safety and Compliance Testing Laboratories
  Performing dust exposure assessments and conformity testing in alignment with European dust safety standards.

• Occupational Health and Safety Authorities
  For establishing baseline requirements in regulations related to dust exposure limits and preventive measures during circular saw operations.

• Tool Users in Woodworking and Construction
  Enhancing awareness of dust exposure risks and encouraging use of dust extraction units or improved work practices based on standardized test data.
