This European Standard was approved by CENELEC on 2017-06-27. CENELEC members are bound to comply with the CEN/CENELEC
Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN-CENELEC
Management Centre or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation
under the responsibility of a CENELEC member into its own language and notified to the CEN-CENELEC Management Centre has the
same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Croatia, Cyprus, the Czech Republic,
Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden,
Switzerland, Turkey and the United Kingdom.

European foreword
The text of document 116/316/FDIS, future edition 1 of IEC 62841-2-21, prepared by IEC/TC 116 "Safety
of motor-operated electric tools" was submitted to the IEC-CENELEC parallel vote and approved by
CENELEC as EN 62841-2-21:2019.
A draft amendment, which covers common modifications to IEC 62841-2-21 (116/316/FDIS), was
prepared by CLC/TC 116 "Safety of motor-operated electric tools" and approved by CENELEC.
The following dates are fixed:
• latest date by which this document has (dop) 2019-11-30
to be implemented at national level by
publication of an identical national
standard or by endorsement
• latest date by which the national (dow) 2023-05-31
standards conflicting with this document
have to be withdrawn
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC shall not be held responsible for identifying any or all such patent rights.
This European Standard is divided into four parts:
Part 1: General requirements which are common to most hand-held electric motor operated tools (for the
purpose of this standard referred to simply as tools) which could come within the scope of this standard;
Part 2, 3 or 4: Requirements for particular types of tools which either supplement or modify the
requirements given in Part 1 to account for the particular hazards and characteristics of these specific
tools.
This Part 2-21 is to be used in conjunction with EN 62841-1:2015.
This Part 2-21 supplements or modifies the corresponding clauses in EN 62841-1:2015, so as to convert
it into the European Standard: Particular requirements for hand-held drain cleaners.
Where a particular subclause of Part 1 is not mentioned in this Part 2-21, that subclause applies as far as
relevant. When 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 smaller roman type.
The terms defined in Clause 3 are printed in bold typeface.
Subclauses, notes, tables and figures which are additional to those in Part 1 are numbered starting
from 101.
Clauses, subclauses, notes, tables, figures and annexes which are additional to those in
IEC 62841-2-21:2017 are prefixed “Z”.
This European Standard follows the overall requirements of EN ISO 12100.
This document has been prepared under a mandate given to CENELEC by the European Commission
and the European Free Trade Association and supports essential requirements of EU Directive.
For the relationship with EU Directive, see informative Annex ZZ, which is an integral part of this
document.
Compliance with the clauses of Part 1 together with this Part 2-21 provides one means of conforming with
the essential health and safety requirements of the Directive concerned.
Endorsement notice
The text of the International Standard IEC 62841-2-21:2017 was approved by CENELEC as a European
Standard with agreed common modifications.
In the official version, for Bibliography, the following note has to be added for the standard indicated:
IEC 62841-3-14 NOTE Harmonized as EN 62841-3-14
COMMON MODIFICATIONS
Replace the title of Annex I by the following:
Annex I
(normative)
Measurement of noise and vibration emissions
Delete the Note.
Replace the existing Subclause I.2.4 with the following:
I.2.4 Installation and mounting conditions of the power tools during noise tests
Addition:
Drain cleaners are suspended in such a way as to correspond to normal use. They are tested with a
drain cleaner cable installed but retracted.
Annex K
(normative)
Battery tools and battery packs
Add the following new subclause:
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.
Compliance is checked by inspection and by manual test.
Annex L
(normative)
Battery tools and battery packs provided with mains connection or
non-isolated sources
Add the following new subclause:
L.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.
Compliance is checked by inspection and by manual test.
