Part 2-114: Particular requirements for Personal-e-Transporters

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.
IEC 60335-2-114 has been prepared by IEC technical committee 61: Safety of household and
similar electrical appliances. It is an International Standard.
This second edition cancels and replaces the first edition published in 2018. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) alignment with IEC 60335-1:2020;
b) change of title of the standard to reflect the expanded scope;
c) expansion of the scope to include a variety of Personal e-Transporters;
d) introduction of UV testing for markings on Personal e-Transporters for shared use in a public
space (7.14);
e) introduction of test probe 19 (8.1.1, 20.2, B.22.3, B.22.4).

– 4 – IEC 60335-2-114:2022 © IEC 2022
The text of this International Standard is based on the following documents:
Draft Report on voting
61/6676/FDIS 61/6752/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard 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/standardsdev/publications.
A list of all parts of the IEC 60335 series, under the general title: Household and similar
electrical appliances – Safety, can be found on the IEC website.
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its
amendments unless that edition precludes it; in that case, the latest edition that does not
preclude it is used. It was established on the basis of the sixth edition (2020) of that standard.
NOTE 1 When "Part 1" is mentioned in this standard, it refers to IEC 60335-1.
This part 2 supplements or modifies the corresponding clauses in IEC 60335-1, so as to convert
that publication into the IEC standard: Safety requirements for Personal-e-Transporters.
When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies as
far as is reasonable. When this standard states "addition", "modification" or "replacement", the
relevant text in Part 1 is to be adapted accordingly.
NOTE 2 The following numbering system is used:
– subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1;
– unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including
those in a replaced clause or subclause;
– additional annexes are lettered AA, BB, etc.
NOTE 3 The following print types are used:
– requirements: in roman type;
– test specifications: in italic type;
notes: in small roman type.
–
Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective and the
associated noun are also in bold.
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,
• replaced by a revised edition, or
• amended.
NOTE 4 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 standard be adopted for implementation nationally
not earlier than 12 months or later than 36 months from the date of publication.
The following differences exist in the countries below.
– This standard is not applicable, instead EN 17128 applies for this kind of appliances
(Germany).
– 6 – IEC 60335-2-114:2022 © IEC 2022
INTRODUCTION
It has been assumed in the drafting of this International Standard that the execution of its
provisions is entrusted to appropriately qualified and experienced persons.
Guidance documents concerning the application of the safety requirements for appliances can
be accessed via TC 61 supporting documents on the IEC website
https://www.iec.ch/tc61/supportingdocuments
This information is given for the convenience of users of this International Standard and does
not constitute a replacement for the normative text in this standard.
This standard only covers the electrical safety of Personal-e-Transporters when operated as in
normal use taking into account the manufacturer's instructions. It also covers abnormal
situations that can be expected in practice and takes into account the way in which
electromagnetic phenomena can affect the safe operation of such appliances.
Other safety aspects of Personal-e-Transporters are covered by the standards developed by
IEC TC 125.
This standard takes into account the requirements of IEC 60364 as far as possible so that there
is compatibility with the wiring rules when the appliance is connected to the supply mains.
However, national wiring rules can differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
When a part 2 standard does not include additional requirements to cover hazards dealt with in
Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal publications, basic safety publications and group safety publications covering a hazard are not
applicable since they have been taken into consideration when developing the general and particular requirements
for the IEC 60335 series of standards.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features that impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of the
requirements and, if found to be substantially equivalent, may be considered to comply with the
standard.
NOTE 3 Standards dealing with non-safety aspects of household appliances are:
– IEC standards published by TC 59 concerning methods of measuring performance;
– CISPR 11, CISPR 14-1 and relevant IEC 61000-3 series standards concerning electromagnetic emissions;
– CISPR 14-2 concerning electromagnetic immunity;
– IEC standards published by TC 111 concerning environmental matters.

SAFETY –
Part 2-114: Particular requirements for Personal-e-Transporters

1 Scope
This clause of Part 1 is replaced by the following.
This part of IEC 60335 deals with the electrical safety of Personal e-Transporters used in the
private or public areas.
The device can have one or more wheels, self-balancing provisions, provisions for the transport
of cargo and can be for private, commercial, shared use or for hire.
Examples of devices that are within the scope of this standard are
– self-balancing transport devices with or without a seat (also known as hover boards);
– electric scooters without a seat including scooters with detachable seats;
– electric mono-wheels with or without a seat;
– electric skateboards.
This standard does not apply to
– appliances intended exclusively for industrial purposes;
– appliances intended to be used in locations where special conditions prevail, such as the
presence of a corrosive or explosive atmosphere (dust, vapour or gas);
– electric mopeds with a seat;
– electric bicycles;
– electric motorcycles;
– devices exclusively intended for use by people with a physical disability such as electrically
powered wheel chairs;
– devices with hybrid power mode such as Personal e-Transporters incorporating a small
internal combustion motor where the internal combustion motor is the primary power source;
– ride-on or walk-behind commercial floor treatment machines (IEC 60335-2-72).
NOTE 101 An electric scooter with a seat is classified as an electric moped and an electric moped without a seat
is classified as an electric scooter.
As far as is practicable, this standard deals with the common electrical safety hazards presented
by Personal e-Transporters that are encountered by all users. However, in general, it does
not take into account
– persons (including children) whose
• physical, sensory or mental capabilities; or
• lack of experience and knowledge
prevents them from using the appliance safely without supervision or instruction;
– children playing with the appliance;

– 8 – IEC 60335-2-114:2022 © IEC 2022
– safety of riding/driving the device including aspects such as maximum attainable speed,
stability, acceleration, braking, visibility, ergonomics, and reliability of driving controls such
as acceleration or braking controls.
Attention is drawn to the fact that
– for appliances intended to be used in vehicles or on board ships or aircraft, additional
requirements can be necessary;
– in many countries, additional requirements are specified by the national health authorities,
the national authorities responsible for the protection of labour, the national transport
authorities and similar authorities.

using flat applicator plates each sized 100 mm × 250 mm. The functional part shall be fitted
with a battery that is fully charged for the test. After the 10 min period of the test, the load is
removed. For PeTs where the battery can be recharged in the appliance, the PeT shall then be
operated for one cycle. For PeTs that are supplied with a battery that is not charged within the
appliance, the PeT is operated under normal operation until the appliance no longer operates.
The PeT shall then be observed for 1 h during which it shall show no damage impairing
compliance with this standard and in particular, there shall be no fire or explosion.
B.21.102 The functional part fitted with a battery that is fully charged shall be designed to
withstand vibrations to which it can be subjected.
Compliance is checked by carrying out the vibration tests specified in IEC 60068-2-64 under
the following conditions:
– the functional part is strapped to the vibration generator with the functional part in its
normal position of use;
– 16 – IEC 60335-2-114:2022 © IEC 2022
– the direction of vibration is vertical;
– the amplitude of vibration is 0,35 mm;
– the sweep frequency range is 10 Hz to 55 Hz;
– the duration of the test is for 1 cycle or 30 min, whichever is longer.
After the test, the PeT shall continue to operate normally and show no damage impairing
compliance with this standard; in particular, no connections and no parts that impair compliance
with this standard shall have loosened. Furthermore, there shall be no fire or explosion or
explosion of the battery.
B.21.103 Additional batteries and interconnecting cords provided with the PeT shall have
means to be securely mounted to the functional part.
Compliance is checked by inspection.

22.1 Addition:
The functional part intended to be used off-road shall have a degree of protection against
access to hazardous parts and against solid foreign objects of at least IP5X, its enclosure being
category 2.
After the test, an inspection shall show that there is no trace of dust on insulation which could
result in a reduction of clearances or creepage distances below the values specified in
Clause 29.
