Electric motor-operated tools - dust measurement procedure - Part 2-6: Particular requirements for hammers

This European Standard specifies general requirements for the dust measurement of electric motor-operated hammers 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.

Overview

EN 50632-2-6:2015/A1:2019 (CLC) defines the dust measurement procedure specific to electric motor-operated hammers. It applies to tools supplied from mains or batteries, with or without dust extraction units, where mineral dust containing silica or wood dust is expected. Amendment A1 (approved 2019-10-21) clarifies procedures for determining the tool mass and specifies the concrete formulation and test block preparation used during dust measurement tests.

Key implementation dates: amendment approved 2019-10-21; latest date for national implementation (DOP) 2020-10-21; conflicting national standards withdrawal (DOW) 2021-10-21.

Key Topics

• Scope and applicability: Measurement method for hammers intended to quantify dust generation under defined conditions and to support evaluation of exposure and dust-control measures.

• Concrete test block specification: The standard requires a concrete block without reinforcement, minimum dimensions 500 mm × 500 mm × 200 mm, made from a specified formulation. The minimum compressive strength after 28 days is 40 N/mm² and the largest aggregate size is 32–40 mm. After the initial 28-day cure, blocks are stored for a further three weeks under dry conditions before testing.

• Concrete formulation guidance: Amendment A1 includes a detailed example formulation (per m³) and instructs on aggregate fraction distribution and prohibited aggregate types (very hard or very soft aggregates such as flint, granite or limestone).

• Test setup and orientation: Holes shall be drilled perpendicular to the block surface on the 500 × 500 mm face, with depths and hole counts as specified by the test tables. For hammers ≤ 5 kg the block is placed on an A-support inclined at 15°; heavier hammers use a block placed on the floor or supported by pallets.

• Tool mass and accessories: Tool mass is measured without flexible cable or separate attachable extraction devices, but including an auxiliary handle if provided and including any integrated dust-extraction parts.

• Operational conditions: New drill bits as specified by manufacturers shall be used; speed and feed settings are adjusted for concrete drilling. Test cycles are defined (e.g., distribution of holes over 10-minute cycles) with allowance to extend cycle time if necessary to complete the required holes.

Applications

• Performance and compliance testing of hammer tools for occupational safety assessment
• Comparative verification of dust extraction or control solutions
• Product development and quality assurance where silica or wood dust emission is a concern

Related Standards

• EN 50632 (general series) and other Part 2-x documents covering dust measurement procedures for different tool types
• CLC/TC 116 publications on safety of motor-operated electric tools

This summary emphasizes practical test setup, material preparation and mass-measurement rules introduced by A1 to ensure repeatable, comparable dust measurement results for hammer-type tools.
