Overview

EN 50632-3-9:2016/A1:2021 is a CENELEC amendment that sets particular requirements for dust measurement on transportable mitre saws. It is part of the EN 50632 series addressing dust measurement procedures for electric motor‑operated tools (mains or battery supplied), with or without dust extraction units. The standard applies where dust such as mineral dust containing silica or wood dust is expected. Amendment A1 (2021) modifies the 2016 text to include clarifications and improvements based on practical tests.

Key topics and technical requirements

• Scope: Dust measurement procedure for transportable mitre saws, tested under load and in conjunction with EN 50632‑1:2015.
• Test material and setup: Use medium‑density fibreboard (MDF) per EN 622‑5, density (750 ± 50) kg/m³, thickness (19 ± 1.0) mm; width = 2/3 of maximum horizontal cutting capacity but not more than 200 mm.
• Orientation and operation: Strips must contact the saw fence; mitre and bevel angles set to 0°.
• Tool conditioning: New saw blade specified by the manufacturer for sawing fibreboard at the start of each test.
• Speed and settings: Speed controls set to the manufacturer’s setting for sawing chipboard where applicable.
• Feed force: Applied to ensure stable operation and good performance; avoid excessive force or speed that would cut through the workpiece too quickly.
• Test cycle and cuts: Defined working time with required number of cuts - 50 cuts for non‑sliding mitre saws, 40 cuts for sliding mitre saws. Testing may extend beyond 10 minutes if required to achieve the number of cuts.
• Test mounting: Mitre saws supplied with a working stand are placed on that stand; others are placed on a test bench with working height matching the vertical distance requirement for dust sampler intakes (per clause 4.2).
• Purpose: Provide repeatable, comparable dust emission data for occupational safety and product evaluation.

Practical applications and users

This standard is useful for:

• Manufacturers of transportable mitre saws validating dust control performance and designing dust extraction.
• Independent test laboratories conducting dust emission measurements and producing certification or technical reports.
• Occupational hygienists and safety officers assessing workplace exposure to wood dust or silica during sawing tasks.
• Procurement and compliance teams specifying tools that meet measurable dust performance criteria.
• Product designers and R&D teams optimizing blade selection, guards, and extraction systems.

Related standards

• EN 50632‑1:2015 (general dust measurement procedure) - to be used in conjunction with Part 3‑9.
• EN 622‑5 - referenced for MDF material specification.
• Developed by CLC/TC 116 (Safety and environmental aspects of motor‑operated electric tools).
