Overview

The FprEN IEC 62841-4-4:202X/FprA1:2024 standard, issued by the CLC, defines the safety requirements for electric motor-operated hand-held tools, transportable tools, and lawn and garden machinery, with a particular focus on lawn trimmers, lawn edge trimmers, grass trimmers, brush cutters, and brush saws. This amendment updates the initial IEC 62841-4-4:2021 standard, enhancing safety, ergonomic design, and operational reliability of these outdoor power tools. It provides manufacturers, testing organizations, and users with detailed guidelines to ensure these tools meet international safety benchmarks aimed at reducing mechanical hazards, improving user protection, and optimizing tool performance.

Key Topics

• Safety Requirements
  The standard specifies rigorous safety measures including maximum speed limits, operator presence sensors, lock-off devices, and guarding systems. It mandates the inclusion of clear warning labels such as "WARNING – Keep bystanders away" to prevent accidental injuries.

• Mechanical Design and Ergonomics
  Specifications for adjustable handles, ergonomic positioning, and grip dimensions (including T-type handles) promote safer and more comfortable user operation. The construction rules ensure guards cover critical blade areas and prevent removal without tools.

• Marking and Instructions
  Tools must be clearly marked with maximum spindle speeds and safety instructions. The standard updates guidance on footwear recommendations to prevent injuries-emphasizing the use of non-slip, protective footwear during operation.

• Noise and Vibration Testing
  Incorporates references to ISO 22867:2021 and ISO 22868:2021 for vibration and noise measurement, providing standardized methods to assess and control environmental and ergonomic impacts of these machines.

• Abnormal Operation and Overspeed Prevention
  Includes mechanisms to prevent output speeds exceeding 130% of the manufacturer’s assigned maximum speed, protecting both the user and the tool from hazardous conditions.

• Mechanical Strength and Durability
  Details drop tests and mechanical stress evaluations to ensure long-term durability and safety even in harsh working conditions.

Applications

This standard specifically applies to a wide range of lawn and garden electric power tools, including:

• Lawn trimmers and grass trimmers used for precise grass cutting
• Lawn edge trimmers designed to create clean boundary lines along lawns
• Brush cutters and brush saws for heavy-duty vegetation and undergrowth removal

By adhering to these requirements, manufacturers can produce safer, reliable, and user-friendly electric motor-operated tools that meet international compliance and market acceptance. Testing labs use this standard as a reference for conformity assessment and certification. End users benefit from enhanced safety features, ergonomic handle designs, and reduced risk during operation, making outdoor landscaping work safer and more efficient.

AMENDMENT 1
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 the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights. IEC shall not be held responsible for
identifying any or all such patent rights.
Amendment 1 to IEC 62841-4-4:2020 has been prepared by IEC technical committee 116:
Safety of motor-operated electric tools.

The text of this Amendment is based on the following documents:
Draft Report on voting
116/806/FDIS 116/829/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this Amendment is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/publications/.
A list of all parts of the IEC 62841 series, under the general title: Electric motor-operated hand-
held tools, transportable tools and lawn and garden machinery – Safety, can be found on the
IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,
• withdrawn, or
• revised.
NOTE The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations may need a transitional period following publication of a new, amended or revised IEC publication in
which to make products in accordance with the new requirements and to equip themselves for conducting new or
revised tests.
It is the recommendation of the committee that the content of this publication be adopted for implementation nationally
not earlier than 36 months from the date of publication.
