Part 2-10: Particular requirements for hand-held mixers

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 62841-2-10 has been prepared by IEC technical committee 116:
Safety of motor-operated electric tools.
The text of this standard is based on the following documents:
FDIS Report on voting
116/303/FDIS 116/313/RVD
Full information on the voting for the approval of this 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 2-10 is to be used in conjunction with the first edition of IEC 62841-1 (2014).
This Part 2-10 supplements or modifies the corresponding clauses in IEC 62841-1, so as to
convert it into the IEC standard: Particular requirements for hand-held mixers.
Where a particular subclause of Part 1 is not mentioned in this Part 2-10, that subclause
applies as far as relevant. 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 website 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.

Annex I
(informative)
Measurement of noise and vibration emissions
NOTE In Europe (EN 62841-2-10), Annex I is normative.
I.2 Noise test code (grade 2)
This clause of Part 1 is applicable except as follows:
I.2.4 Installation and mounting conditions of the power tools during noise tests
Addition:
Mixers are suspended vertically with no mixer basket installed.
I.2.5 Operating conditions
Addition:
Mixers are tested at no-load, all speed setting devices adjusted to the highest value.
I.3 Vibration
This clause of Part 1 is applicable except as follows:
I.3.3.2 Location of measurement
Addition:
Figure I.101 shows the position for different types of tools.
I.3.5.3 Operating conditions
Addition:
Mixers are tested at no-load, all speed setting devices adjusted to the highest value. During
the test, the tool is held vertically.
For the test, one simulated test mixer basket with a specified unbalance as shown in
Figure I.102 is mounted to the output spindle or, for tools with more than one output spindle,
to one of the output spindles. The test mixer basket consists of a steel rod and an aluminium
wheel with an unbalance, see Figure I.103, mounted appropriately to the steel rod. The upper
end of the steel rod may be modified in order to fit to the output spindle.
NOTE Experimental investigations have shown that the vibration emission values of mixers when mixing material
are similar or even lower than at no-load, because the main source of vibration is the unbalance of the mixer
basket(s). Hence, the above test results in a worst case value.
I.3.6.2 Declaration of the vibration total value
Addition:
The vibration total value a of the handle with the highest emission and the uncertainty K shall
h
be declared.

a clause is stated in this annex, its requirements replace the requirements of the main body of
this Part 2-10 unless otherwise specified.
K.8.14.1.101 Items d), f) and h) are not applicable.
K.12.2.1 This subclause is not applicable.
NOTE In Europe (EN 62841-2-10), the following additional subclause applies:
K.21.18.Z101 Isolation and disabling device
Tools with an integral battery shall either be equipped
– with an isolation device to prevent the risk of injury from mechanical hazards during servicing or user
maintenance; or
– with a disabling device that prevents unintentional starting of the tool.
An isolation device shall
– provide disconnection of all poles of the battery from the serviceable region of the tool;
– be equipped with an unambiguous indication of the state of the disconnection device which corresponds to
each position of its manual control (actuator);
– be provided with protection against accidental reconnection.
NOTE 1 Examples of methods to achieve this disconnection include removable jumpers, integral batteries
that can be disconnected for servicing or user maintenance, or an electromechanical power switch with a
direct mechanical link between the actuator and the contact.
NOTE 2 The risk of accidental reconnection for a power switch is addressed by the requirement of
21.18.1.2. The other examples in NOTE 1 achieve this by the necessary actions for reconnection.
A disabling device may be achieved by any of the following:
– a self-restoring or non-self-restoring lock-off device where two separate and dissimilar actions are
necessary before the motor is switched on (e.g. a power switch which has to be pushed in before it can
be moved laterally to close the contacts to start the motor). It shall not be possible to achieve these two
actions with a single grasping motion or a straight line motion;
– a removable disabling device provided with the tool where it shall not be possible for the tool to be
operated when either applied or removed.

direct mechanical link between the actuator and the contact.
NOTE 2 The risk of accidental reconnection for a power switch is addressed by the requirement of
21.18.1.2. The other examples in NOTE 1 achieve this by the necessary actions for reconnection.
A disabling device may be achieved by any of the following:
– a self-restoring or non-self-restoring lock-off device where two separate and dissimilar actions are
necessary before the motor is switched on (e.g. a power switch which has to be pushed in before it can
be moved laterally to close the contacts to start the motor). It shall not be possible to achieve these two
actions with a single grasping motion or a straight line motion;
– a removable disabling device provided with the tool where it shall not be possible for the tool to be
operated when either applied or removed.
Compliance is checked by inspection and by manual test.

AVANT-PROPOS
1) La Commission Electrotechnique Internationale (IEC) est une organisation mondiale de normalisation
composée de l'ensemble des comités électrotechniques nationaux (Comités nationaux de l'IEC). L'IEC a pour
objet de favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines
de l'électricité et de l'électronique. A cet effet, l'IEC – entre autres activités – publie des Normes
internationales, des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au
public (PAS) et des Guides (ci-après dénommés "Publication(s) de l'IEC"). Leur élaboration est confiée à des
comités d'études, aux travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les
organisations internationales, gouvernementales et non gouvernementales, en liaison avec
