Electric motor-operated tools - Dust measurement procedure - Part 2-22: Particular requirements for cut-off machines and wall chasers

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 cut-off machines and wall chasers.

Overview

EN 50632-2-22:2015/A1:2021 - Amendment A1 to the 2015 European Standard - defines particular dust measurement requirements for electric motor‑operated cut-off machines and wall chasers. Part 2-22 is intended to be used together with EN 50632‑1:2015 and applies to mains- or battery‑supplied tools, with or without dust extraction, where mineral dust (including silica) or wood dust is expected. The 2021 amendment clarifies operating conditions, test set-ups and figures used in laboratory dust emission testing.

Key topics and requirements

• Scope: Measurement of airborne dust emissions from cut-off machines and wall chasers during representative cutting operations.
• Test materials & conditioning:
  • Cut‑off machines: concrete slabs (EN 1339:2003 dimensions and classes) stored dry for specified periods.
  • Wall chasers: calcium‑silicate blocks with defined density, thickness and pre‑storage requirements.
• Test procedures:
  • Defined slot depths and cutting patterns (e.g., number and length of cuts; horizontal vs vertical portions for wall chasers).
  • Minimum total cutting lengths per test depending on tool rated capacity or maximum depth of cut.
  • Operator positioning and laboratory set‑up according to revised Figures 101 and 102.
• Tool setup:
  • Use of new or freshly re‑sharpened diamond wheels as specified by the manufacturer.
  • Speed and feed force settings: speed per cutting material, feed force sufficient for stable, representative operation.
• Instrumentation: placement of dust samplers with specified vertical distance from the workpiece (see EN 50632‑1 for general measurement methods).
• Purpose of amendment: improvements and clarifications based on practical testing experience.

Applications and users

This standard is practical for:

• Manufacturers of cut‑off machines and wall chasers - to quantify emissions and validate dust‑control designs.
• Test laboratories and certification bodies - for repeatable, comparable dust emission testing and compliance verification.
• Occupational health & safety professionals and consultants - to evaluate exposure risks and specify control measures (dust extraction, PPE).
• Product developers and purchasers - to compare performance of extraction systems and document safer tool choices.

Practical benefits: standardized test methods enable consistent assessment of airborne dust emissions (including silica), support product improvement, demonstrate compliance, and inform workplace risk assessments.
