Part 3-9: Particular requirements for transportable mitre saws

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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62841-3-9 has been prepared by IEC technical committee 116:
Safety of motor-operated electric tools.
This second edition cancels and replaces the first edition published in 2014. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Clause 1: Scope: increase of the maximum saw blade diameter to 410 mm;
b) Corrigendum 1 and Corrigendum 2 of the first edition have been incorporated in this
second edition.

The text of this International Standard is based on the following documents:
FDIS Report on voting
116/430/FDIS 116/442/RVD

Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
This Part 3-9 is to be used in conjunction with the IEC 62841-1:2014.
This Part 3-9 supplements or modifies the corresponding clauses in IEC 62841-1, so as to
convert it into the IEC Standard: Particular requirements for transportable mitre saws.
Where a particular subclause of Part 1 is not mentioned in this Part 3-9, that subclause
applies as far as reasonable. Where this standard states “addition”, “modification” or
“replacement”, the relevant text in Part 1 is to be adapted accordingly.
The following print types are used:
– requirements: in roman type;
– test specifications: in italic type;
– notes: in small roman type.
The terms defined in Clause 3 are printed in bold typeface.
Subclauses, notes and figures which are additional to those in Part 1 are numbered starting
from 101.
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 publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
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.
IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct
understanding of its contents. Users should therefore print this document using a
colour printer.

4 General requirements
This clause of Part 1 is applicable, except as follows:
4.101 Throughout the remaining part of this document, unless otherwise explicitly stated,
whenever a requirement or a reference is made to
– “saw blade”:
this shall equally apply to any “saw blade” as specified in accordance with 8.14.2 a);
– “force” as a multiple of D:
the force shall be expressed in newtons (N) and the saw blade diameter D shall be
expressed in millimetres (mm).
5 General conditions for the tests
This clause of Part 1 is applicable, except as follows:
5.17 Addition:
The mass of the tool shall include the fences and required workpiece clamp(s) in accordance
with 21.103 and 21.104. Further parts such as carrying means that are required in accordance
with the instructions for the safe use of the tool shall be included in the mass.
5.101 Procedure to determine the horizontal cutting capacity
The mitre saw is fitted with a (2 ± 0,2) mm thick steel disc of diameter D in place of the saw
blade and is set to 0° bevel angle. The saw unit is at its fully down position and, for a
mitre saw with a sliding function, the saw unit is at its maximum extended horizontal position
from the fence. The mitre saw is set for the mitre angle for which the horizontal cutting
capacity measurement is desired.
Horizontal cutting capacity:
The horizontal cutting capacity is the perpendicular distance measured in the plane of the
table top from the fence to the intersect point of the steel disc periphery in quadrant “C” with
the plane of the table top.
6 Radiation, toxicity and similar hazards
This clause of Part 1 is applicable.
7 Classification
This clause of Part 1 is applicable.
8 Marking and instructions

This symbol needs not be in accordance with the colour requirements of ISO 3864-2.
8.14.1 Addition:
The additional safety instructions as specified in 8.14.1.101 shall be given. This part may be
printed separately from the “General Power Tool Safety Warnings”.
8.14.1.101 Safety instructions for mitre saws
a) Mitre saws are intended to cut wood or wood-like products, they cannot be used
with abrasive cut-off wheels for cutting ferrous material such as bars, rods, studs,
etc. Abrasive dust causes moving parts such as the lower guard to jam. Sparks from
abrasive cutting will burn the lower guard, the kerf insert and other plastic parts.
b) Use clamps to support the workpiece whenever possible. If supporting the
workpiece by hand, you must always keep your hand at least 100 mm from either
side of the saw blade. Do not use this saw to cut pieces that are too small to be
securely clamped or held by hand. If your hand is placed too close to the saw blade,
there is an increased risk of injury from blade contact.
c) The workpiece must be stationary and clamped or held against both the fence and
the table. Do not feed the workpiece into the
...
