SIST EN 50632-2-5:2016

Overview

SIST EN 50632-2-5:2016 is a European Standard developed by CLC that specifies the dust measurement procedure tailored for hand-held electric motor-operated circular saws. This standard forms Part 2-5 of the EN 50632 series and supplements the general dust measurement requirements set out in EN 50632-1:2015. It specifically addresses the testing conditions, instrumentation, and reporting criteria required to accurately measure dust emissions produced by circular saws during operation.

The primary focus of SIST EN 50632-2-5:2016 is to control and quantify inhalable and respirable dust concentrations generated by circular saws, which is critical for ensuring user safety and compliance with occupational health standards.

Key Topics

• Scope and Application:
  Applies exclusively to circular saws intended for wood cutting, particularly chipboard, as part of the broader category of motor-operated electric tools.

• Test Procedure & Operating Conditions:

  • Sawing wood chipboards (P2 according to EN 312:2010) with specified dimensions and density.
  • Performing 30 cuts of approximately 10 mm strips over a 400 mm width using a guide rail or rip fence setup.
  • Cutting depth set to approximately 30 mm and speed/feed force adjusted to maintain stable, efficient operation.
  • Typical test cycle duration is 10 minutes but may be extended if the number of cuts cannot be completed within this timeframe.

• Instrumentation:
  Precise measurement instruments as defined in Part 1 of EN 50632 are used to capture dust emission data during testing.

• Reporting Requirements:
  Includes detailed documentation of operating parameters and any adjustments to the standard test cycle, especially if cycle times are extended.

Applications

• Workplace Safety Compliance:
  Organizations manufacturing or using circular saws can utilize this standard to evaluate dust emissions, helping to minimize worker exposure to harmful dust and comply with occupational health regulations.

• Product Development & Quality Control:
  Manufacturers can assess and improve saw designs by monitoring particulate emissions, potentially integrating dust reduction features to enhance tool safety and marketability.

• Environmental and Health Risk Assessments:
  Dust measurement data derived using EN 50632-2-5 supports risk management efforts by providing quantifiable exposure metrics for inhalable and respirable dust generated during wood cutting operations.
