Overview

IEC 63241-2-5:2024 is an international standard published by the International Electrotechnical Commission (IEC) that defines the dust measurement procedure for hand-held circular saws used in electric motor-operated tools. It supplements the general requirements established in IEC 63241-1:2023 with particular provisions tailored specifically for circular saws. This standard ensures consistent, accurate measurement of dust emissions generated during the operation of circular saws, addressing occupational safety and environmental concerns related to dust exposure.

By establishing standardized test methods and reporting procedures, IEC 63241-2-5 helps manufacturers, testing laboratories, and regulatory bodies maintain high safety standards and reduce health risks associated with airborne particles generated by sawdust during wood cutting.

Key Topics

  • Scope and Application
    The standard applies exclusively to hand-held circular saws designed for cutting materials such as wood and particleboard. It focuses on dust measurement during typical sawing operations.

  • Test Procedures
    The standard specifies detailed test conditions, including the type and dimensions of the test material, cutting parameters, and operator positioning. For example, the saw is tested using particleboard with specific density and mechanical properties (e.g., density 610 kg/m³, thickness 19 mm), cutting 10 mm wide strips. The circular saw must be equipped with a new blade as per manufacturer specifications, and tests involve performing 30 cuts per test cycle.

  • Instrumentation and Setup
    The standard outlines requirements for instrumentation used in dust measurement, ensuring consistent sampling near the tool's dust intake openings. It also specifies operator orientation relative to the workpiece and tool to simulate real working conditions accurately.

  • Performance Reporting
    Test reports must include detailed information such as operating conditions, cutting depth, feed force, cycle time, and any extensions needed if the standard 30 cuts cannot be performed within 10 minutes. This comprehensive reporting supports transparency and comparability of test results.

Applications

  • Tool Manufacturers
    Tool designers and manufacturers use IEC 63241-2-5 to evaluate and optimize the dust emissions of their hand-held circular saw models. Compliance with this standard demonstrates product safety and helps meet regulatory requirements.

  • Testing Laboratories
    Accredited testing labs implement this standard to perform reliable, reproducible dust emission measurements on circular saws. Standardized testing facilitates certification and aids manufacturers in product validation.

  • Occupational Safety and Health
    Employers and safety professionals leverage the insights from dust emission data to improve workplace safety practices, reduce workers’ exposure to harmful dust, and select equipment that meets dust containment criteria.

  • Regulatory Bodies
    Regulatory agencies may reference IEC 63241-2-5 when establishing safety regulations and limits for dust exposure in construction and woodworking industries.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
