environmental aspects of motor-operated electric tools”.
The following dates are fixed:
• latest date by which this document has to be (dop) 2022-06-07
implemented at national level by publication of
an identical national standard or by
endorsement
• latest date by which the national standards (dow) 2025-06-07
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withdrawn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 series 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 document referred to simply as tools) which could come within the scope of
this document;
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.
The Part 4-5 is to be used in conjunction with EN 62841-1:2015 and its amendments.
The Part 4-5 supplements or modifies the corresponding clauses in EN 62841-1:2015, so as to convert it into
the European Standard: Particular requirements for grass shears.
Where a particular subclause of Part 1 is not mentioned in the Part 4-5, that subclause applies as far as relevant.
When this document 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 62841-4-5:20XX
are prefixed “Z”.
This document follows the overall requirements of EN ISO 12100.
This document has been prepared under a Standardization Request given to CENELEC by the European
Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s)
/ Regulation(s).
For relationship with EU Directive(s) / Regulation(s), see informative Annex ZZ, which is an integral part of this
document.
Compliance with the clauses of Part 1 together with Part 4-5 provides one means of conforming with the
essential health and safety requirements of the Directive concerned.
Any feedback and questions on this document should be directed to the users’ national committee. A complete
listing of these bodies can be found on the CENELEC website.
EN IEC 62841-4-5:2020/A11:2021 (E)
1 Modification to Clause 1, “Scope”
Add the following to the existing Clause 1:
“This document covers all significant hazards, hazardous situations or hazardous events relevant for machines
covered by this document.
NOTE Z101 Essential requirements not mentioned in Table ZZ.1 are deemed to be not applicable, because the
corresponding hazards are either not relevant for machines covered by this standard or do not require specific action by the
designer.”
2 Modification to Annex I, “Measurement of noise and vibration emissions”
Replace the title of Annex I with the following:
“Annex I
(normative)
Measurement of noise and vibration emissions”
and delete the NOTE.
Replace the existing Subclause I.2.3.1 with the following:
“I.2.3.1 Hand-held tools
The A-weighted emission sound pressure level at the work station, LpA, shall be determined in accordance with
EN ISO 11203:2009 as follows:
LpA = LWA - Q
where Q = 8 dB.
NOTE 1 This value of Q has been determined, during experimental investigations, to be applicable to hand-held power
tools. The resulting A-weighted emission sound pressure level at the workstation is equivalent to the value of the surface
sound pressure level at a distance of 0,7 m from the power tool. This distance has been chosen to give satisfactory
reproducibility of results, and to permit comparison of the acoustic performance of different hand-held power tools, which
do not, in general, have uniquely defined work stations. Under free field conditions, where it could be required to estimate
the emission sound pressure level, L , at a distance r in m from the geometric centre of the power tool, this can be done
pA,r1 1
by applying the formula:
0,7
L = L + 20 lg () dB
pA,r1 pA
r
NOTE 2 At any given position in relation to a particular machine, and for given mounting and operating conditions, the
emission sound pressure levels determined by the method of this document will in general be lower than the directly
measured sound pressure levels for the same machine in the typical workroom where it is used. This is due to the influence
of sound reflecting surfaces in the workroom compared to the free field conditions of the test specified here. A method of
calculating the sound pressure levels in the vicinity of a machine operating alone in a workroom is given in ISO/TR 11690-3.
Commonly observed differences are 1 dB to 5 dB, but in extreme cases the difference might be even greater.
If required, the C-weighted peak emission sound pressure level L shall be measured at each of the five
pC,peak
measurement positions specified in I.2.2. The C-weighted peak emission sound pressure level at the work
station is the highest C-weighted peak emission sound pressure level measured at any of the five microphone
positions; no corrections are permitted.”
3 Modification to Annex K, “Battery tools and battery packs”
Replace the NOTE 101 in subclause K.21.18 with the following normative text:
“K.21.18.Z101 Isolation and disabling device
Machines 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 machine.
An isolation device shall:
— provide disconnection of at least one pole of the battery from the serviceable region of the machine;
— 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 21.18.103. 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 machine where it shall not be possible for the machine to
be operated when either applied or removed.
Compliance is checked by inspection and by manual test.”
4 Modification to Annex L, “Battery tools and battery packs provided with mains
connection or non-isolated sources”
Replace the NOTE 101 in subclause L.21.18 with the following normative text:
“L.21.18.Z101 Isolation and disabling device
Machines 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 machine.
An isolation device shall:
— provide disconnection of at least one pole of the battery from the serviceable region of the machine;
— be equipped with an unambiguous indication of the state of the disconnection device which corresponds to
each position of its manual control (actuator);
EN IEC 62841-4-5:2020/A11:2021 (E)
— 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 21.18.103. 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

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 machine where it shall not be possible for the machine to
be operated when either applied or removed.
Compliance is checked by inspection and by manual test.”
