Overview
IEC 63241-3-9:2025 is an international standard published by the International Electrotechnical Commission (IEC) that specifies dust measurement procedures tailored specifically for transportable mitre saws. This part of the IEC 63241 series supplements the general requirements outlined in IEC 63241-1:2023, focusing on particularities related to mitre saws designed for cutting wood and wood-based materials such as particleboard.
The standard ensures manufacturers and testing organizations have a clear framework to evaluate dust emissions, promoting workplace safety and environmental compliance. It defines test conditions, instrumentation, and reporting requirements to measure airborne dust generated during the operation of transportable mitre saws.
Key Topics
Scope: Targets transportable mitre saws intended primarily for cutting wood or wood-based materials including particleboard conforming to standards like EN 312 P2, ISO 16893 P-FN REG, and ANSI A208.1 Grade M-S.
Test Procedures:
- Includes detailed operating conditions covering type of material, thickness, and dimensions of workpieces.
- Specifies saw blade conditions, speed settings, and forces applied during testing.
- Mandates a fixed number of test cuts-50 cuts for non-sliding mitre saws or 40 cuts for sliding models-to simulate typical usage.
- Requires mitre and bevel angles both set to 0° to standardize cuts.
Instrumentation Requirements: Adheres to measurement specifications from IEC 63241-1:2023, ensuring consistency in dust sampling and analysis.
Reporting: Requires comprehensive documentation, including any extensions to the test cycle time if the cut number cannot be completed within the standard 10-minute period.
Definitions: Clarifies terms specific to mitre saws, such as the saw unit, table top, plunging and sliding actions, and angles for compound cuts.
Operating Conditions Summary: Presented in Table 101 of the standard, including:
- Workpiece density (~610 kg/m³),
- Strength characteristics,
- Material thickness (19 ± 1 mm),
- Width related to 2/3 of maximum horizontal cutting capacity (max 200 mm).
Applications
Manufacturer Compliance: Enables producers of transportable mitre saws to meet international safety and environmental standards by providing validated dust emission testing protocols.
Workplace Safety: Helps businesses ensure that mitre saw operation aligns with occupational health guidelines by quantifying dust exposure, critical for preventing respiratory issues related to wood dust.
Product Testing & Certification: Supports third-party testing laboratories with a harmonized methodology to assess saw dust emissions, facilitating product certification and market acceptance globally.
Standardization of Testing Methods: Provides a unified approach for equipment manufacturers and testing bodies to assess dust emissions under controlled, reproducible conditions, increasing test result reliability.
Design Guidance: Supplies insights into dust control effectiveness in mitre saw designs, encouraging innovation in dust collection systems and mitigation technologies.

Practical Value
Adoption of IEC 63241-3-9:2025 will streamline dust emission testing for transportable mitre saws, providing:
- Consistent dust measurement protocols ensuring fair product comparison and regulatory compliance.
- Improved health and safety outcomes by enforcing dust control evaluation at the design and manufacturing stages.
- Clear guidance for transitional periods, allowing manufacturers and testing bodies adequate time (recommended 36 months post-publication) to adapt to the updated requirements.
- A technical foundation for ongoing innovation in dust extraction and mitigation technologies for power tools.

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.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that
