Part 2-45: Particular requirements for portable heating tools
and similar appliances
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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 60335-2-45 has been prepared by IEC technical committee 61: Safety of household and
similar electrical appliances. It is an International Standard.
This fourth edition cancels and replaces the third edition published in 2002, Amendment 1:2008
and Amendment 2:2011. 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) deletion or conversion of some notes to normative text (Clause 1, 5.2, 15.101, 22.105, 25.7);

c) introduction of external accessible surfaces temperature limits, including addition of
functional surface and hot surface requirements (3.6.101, 7.1, 7.6, 7.12, 7.14, 7.15, 11.3,
11.8);
The text of this International Standard is based on the following documents:
Draft Report on voting
61/7296/FDIS 61/7341/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/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: Particular requirements for portable heating tools and
similar appliances.
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 following differences exist in the countries indicated below.
– 6.1: Class 0 appliances are allowed if their rated voltage does not exceed 150 V and class
0I appliances are allowed (Japan).
– 25.7: The modification does not apply (Japan).

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, or
• revised.
NOTE 4 The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations can 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.
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 recognizes the internationally accepted level of protection against hazards such
as electrical, mechanical, thermal, fire and radiation of appliances 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 appliances.
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 2-45: Particular requirements for portable heating tools
and similar appliances
1 Scope
This clause of Part 1 is replaced by the following.
This part of IEC 60335 deals with the safety of portable electric heating tools and similar
appliances, their rated voltage being not more than 250 V including direct current (DC)
supplied appliances and battery-operated appliances.
Appliances not intended for normal household use, but which nevertheless can be a source of
danger to the public, such as appliances intended to be used by laypersons in shops, in light
industry and on farms, are within the scope of this standard.
Appliances that can also be used when mounted on a support are within the scope of this
standard.
Examples of appliances that are within the scope of this standard are
– branding tools;
– burning-in pens;
– conduit-soldering tools;
– dehorning tools;
– desoldering irons;
– firelighters;
– glue guns;
– heat guns;
– household film-welding appliances;
– paint strippers;
– plastic-cutting tools;
– soldering guns;
– soldering irons;
– stripping pliers;
– thermoplastic conduit-welding tools.
As far as is practicable, this standard deals with the common hazards presented by appliances
which are encountered by all persons in and around the home. However, in general, it does not
in general 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.

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 and similar authorities.
This standard does not apply to:
– hand-held motor-operated electric tools (IEC 60745 series, IEC 62841 series);
– transportable motor-operated electric tools (IEC 61029 series, IEC 62841 series);
– 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);
– tools using high-frequency heating other than induction soldering irons;
– arc-welding equipment.

This requirement does not apply to parts operating at safety extra-low voltage.
Compliance is checked by the following test.
A plastic bag is filled with 40 ml of the spillage solution specified in 15.2. The bag is positioned
so that the surface of the water is at the same level as the suction opening of the appliance.
The bag is then welded with the suction device in operation.
The appliance shall then withstand the electric strength test of 16.3 and inspection shall show
that there is no trace of water on the insulation that could result in a reduction of clearances
and creepage distances below the values specified in Clause 29.
16 Leakage current and electric strength
This clause of Part 1 is applicable except as follows.
16.1 Addition:
Appliances supplied by a transformer and induction soldering irons are tested as
motor-operated appliances.
17 Overload protection of transformers and associated circuits
This clause of Part 1 is applicable except as follows.
Addition:
The test is not carried out on soldering guns and other appliances in which the heating element
is part of the secondary circuit of a transformer.
18 Endurance
This clause of Part 1 is not applicable.
19 Abnormal operation
This clause of Part 1 is applicable except as follows.
19.1 Addition:
For heat guns and hot-air firelighters, compliance is also checked by the test of 19.101.
19.2 Replacement:
Appliances are operated under the conditions specified in Clause 11 but supplied at 0,94 times
rated voltage. However, appliances in which the heating element is part of the secondary circuit
of a transformer are operated continuously for 30 min unless they incorporate a biased-off
switch, in which case they are operated for 5 min. Firelighters are operated for 2 h without
adding fuel.
Paint strippers incorporating integral scrapers are held horizontally in a clamp over the entire
length of the handle. A force of 70 N is exerted on the scraper edge in the direction
corresponding to normal use.
19.3 Replacement:
The test of 19.2 is repeated but with the appliance supplied at 1,06 times rated voltage.
19.4 Addition:
Thermoplastic conduit-welding tools are operated with the fastest possible sequence of
welding operations.
19.13 Addition:
The temperature rise of the windings of induction soldering irons shall not exceed the values
specified in 19.7.
The electric strength test of induction soldering irons is carried out immediately after
switching off the appliance.
19.101 Heat guns and hot-air firelighters are operated as specified in Clause 11 until steady
conditions are established. The voltage at the terminals of the motor is then reduced until the
running speed of the motor is just sufficient to prevent the thermal cut-out from operating, the
power input to the heating element being maintained at 1,15 times rated power input.
The voltage is decreased at
– 1 V per minute, for motors having a working voltage not exceeding 30 V;
– 5 V per minute, for motors having a working voltage exceeding 30 V.
The appliances are then operated until steady conditions are established.
20 Stability and mechanical hazards
This clause of Part 1 is applicable except as follows.
20.1 Addition:
Hand-held appliances are subjected to the test while placed on their stands.
20.101 Contact firelighters shall have adequate stability.
Compliance is checked by the following test.
The firelighter is placed on a horizontal surface positioned 1 m above the floor. The maximum
insertion mark specified in 7.1 is aligned with the edge of the surface. The supply cord is
allowed to hang freely, the remaining length allowed to lie on the floor.
The appliance shall not tilt.
21 Mechanical strength
This clause of Part 1 is applicable except as follows.
21.1 Addition:
For hand-held appliances, compliance is also checked by the tests of 21.101.

– 18 – IEC 60335-2-45:2024 © IEC 2024
For contact firelighters, compliance is also checked by the test of 21.102.
21.101 The supply cord of hand-held appliances is cut to a length of 100 mm, measured
from the point where the cord, or cord guard, enters the appliance.
The appliance is dropped from a height of 1 m on to a hardwood base having a thickness
of 50 mm.
This test is carried out five times, the appliance positioned so that its major axis is horizontal
and so that a different part of the appliance is exposed to the impact each time.
The appliance is then dropped five times with its major axis vertical and with tips of soldering
irons, or corresponding parts of other appliances, pointing downwards.
The appliance shall not be damaged to such an extent that compliance with this standard is
impaired, in particular compliance with 8.1.1 shall not be impaired.
21.102 The handle of a new contact firelighter is held firmly between two lightly padded
surfaces with the heating element in a horizontal plane. The firelighter is supplied at rated
voltage. After 3 min a mass of 4,5 kg is suspended at the end of the heating element for 1 min.
The mass is removed and the element is allowed to cool. If the element has been bent, it is
straightened to its original position.
After the test, the appliance shall comply with 8.1.1 and the firelighter shall withstand the
electric strength test of 16.3.
