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 not 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.
Amendment 1 to IEC 62841-2-5:2014 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
116/860/FDIS 116/878/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
© IEC 2025
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.

19 Mechanical hazards
Add, after 19.106, the following new subclauses:
19.107 Guarding system – Longevity
19.107.1 To provide sufficient endurance for extended use, the guarding system shall have
a longevity of 50 000 operating cycles.
Compliance is checked by a new saw sample completing the following test.
The saw is to be set for 0° bevel angle with the base plate in horizontal position and the blade
removed. The lower guard, or the guarding system as shown in Figure 104, is retracted from
the fully closed position to the maximum open working position and then released. This
sequence is repeated at a rate not less than 10 cycles per minute.
The sample used for this test may be positioned in a manner other than horizontal provided that
it can be shown that the alternate position is equal or more severe.
After completion of cycling test as specified above, the saw shall then comply with the tests of
19.107.2 and 19.107.3.
19.107.2 The test and measurement is carried out at maximum depth of cut and 0° bevel
angle. The saw is held or secured with the base plate in a horizontal position, the upper guard
being at the top.
Without any restoration or cleaning, the lower guard as shown in Figures 101, 102 and 103, or
the guarding system as shown in Figure 104, is retracted fully and then allowed to close. The
closing time from the fully open position to the fully closed position shall not exceed 0,3 s.
19.107.3 The following tests and measurements are carried out at maximum depth of cut, at
0° bevel angle and in the following positions:
a) The saw is held with the base plate in the horizontal position, with the upper guard being
at the top.
b) The saw is then held with the base plate in the vertical position, with the front of the saw
pointing upwards.
© IEC 2025
For saws using a lower guard as shown in Figures 101 and 102, the lower guard is retracted
fully and then allowed to close. Without any alteration, the final position of the lower guard in
both cases shall be such that
– the lower guard stopper is present with all of its components (lower guard stopper
components may show wear as a result of the test); and
– the lower guard is in contact with the stopper; and
– if a gap occurs between the rear portion of the lower guard and the upper guard with the
base plate in the horizontal position, the guarding is evaluated in accordance with the
requirements of 19.102.3.
For saws using a lower guard as shown in Figure 103 or a guarding system as shown in
Figure 104, the lower guard or the guarding system is fully retracted, released and then shall
lock in the blade covering position.
19.108 Guarding system – Resistance
19.108.1 The guarding system shall be resistant against environmental and foreseeable dust
accumulation.
Compliance is checked by the tests of 19.108.2 and 19.108.3, as applicable.
During the tests, ventilation in the test area is permitted providing that air flow does not influence
the distribution of dust within the tool.
19.108.2 For a saw intended to cut wood based materials in accordance with 8.14.2 b) 104),
a new saw sample is subjected to 1 000 cuts through each of the materials and in the order as
specified below:
a) crosscutting soft wood;
b) crosscutting plywood with a minimum of 5 layers;
and
c) cutting standard medium density fibreboard (MDF) having a density between 650 kg/m
850 kg/m .
The materials are stored indoors for 72 h prior to sawing. The thickness and length of each
material to be cut may vary in size, provided the thickness of the material is minimum 10 mm
and the cross sectional area of each cut is at least 30 mm times D.
Each cut is made with the saw set to 0° bevel angle and maximum depth of cut. The cutting
is conducted with a carbide-tipped general purpose combination blade. An external dust
extraction system attached to the saw shall not be used. A non-detachable dust collection
system shall be maintained per 8.14.2 b) 105).
NOTE Use of personal protective equipment will help to protect the operator during these tests.
During each cut, the lower guard or the guarding system shall cycle from the fully closed
position to the maximum open working position for each cutting cycle, without manual
assistance. Moreover, for plunge type saws with a spring loaded riving knife, the riving knife
shall cycle from its fully extended to the fully retracted position.
If the lower guard, guarding system or the riving knife fails to return to its normal position at
any time during the test, this is considered a failure.
After completion of all cuts as specified above, the saw is conditioned for 24 h in air at a relative
humidity of (93 ± 3) %. The temperature of the air is maintained within 2 K of any convenient
value between 20 °C and 30 °C.
The saw shall then comply with the tests of 19.107.2 and 19.107.3.

19.108.3 For a saw intended to cut materials such as plastic, metal or masonry in accordance
with 8.14.2 b) 104), a new saw sample for each specified material is subjected to the tests as
specified below.
− Plastics: 1 000 cuts through PVC. The thickness and length of the material may vary in size,
provided the cross sectional area of each cut is at least 0,012 D .
NOTE 1 The above formula simulates the cross sectional area of typical PVC pipes of a diameter approximately
equal to 2/3 of the maximum depth of cut of the saw. Sawing of such pipes is the predominant application for
plastic.
− Ferrous metals: 200 cuts through one sample material of ferrous metal, as if applicable, in
accordance with 8.14.2 b) 104). The thickness and length of the material may vary in size,
1,46 2
provided the cross sectional area of each cut is at least 0,13 D in mm , where D is
measured in mm.
NOTE 2 The above formula simulates the cross sectional area of typical metal pipes of a diameter
approximately equal to 1/2 of the maximum depth of cut of the saw. Sawing of such pipes is the predominant
application for metal.
− Non-ferrous metals: 200 cuts through one sample material of non-ferrous metal, if
applicable, in accordance with 8.14.2 b) 104). The thickness and length of the material may
1,46 2
vary in size, provided the cross sectional area of each cut is at least 0,13 D in mm ,
where D is measured in mm.
− Masonry: 500 cuts through masonry fibreboard (fibre cement board). The thickness and
length of the fibreboard may vary in size, provided the thickness of the material is minimum
10 mm and the cross sectional area of each cut is at least 30 mm times D.
Each cut is made with the saw set to 0° bevel angle. The depth of cut, the saw blade and the
rate of sawing shall be as specified for the respective material. An external dust extraction
system attached to the saw shall not be used. A non-detachable dust collection system shall
be maintained per 8.14.2 b) 105).
NOTE 3 Use of personal protective equipment will help to protect the operator during these tests.
During each cut, the lower guard or the guarding system shall cycle from the fully closed
position to the maximum open working position for each cutting cycle, without manual
assistance. Moreover, for plunge type saws with a spring loaded riving knife, the riving knife
shall cycle from its fully extended to the fully retracted position.
If the lower guard, guarding system or the riving knife fails to return to its normal position at
any time during the test, this is considered a failure.
After completion of all cuts as specified above, the saw is conditioned for 24 h in air at a relative
humidity of (93 ± 3) %. The temperature of the air is maintained within 2 K of any convenient
value between 20 °C and 30 °C.
The saw shall then comply with the tests of 19.107.2 and 19.107.3.
