HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES – SAFETY –
Part 2-90: Particular requirements for commercial microwave ovens
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.
This part of International Standard IEC 60335 has been prepared by subcommittee 61B: Safety
of microwave appliances for household and commercial use, of IEC technical committee 61:
Safety of household and similar electrical appliances.
This fourth edition cancels and replaces the third edition published in 2006 including its
Amendment 1 (2010) and Amendment 2 (2014). It constitutes a technical revision.
The principal changes with respect to the previous edition are as follows (minor and editorial
changes are not listed):
– a statement in 7.12 is required for appliances intended to be used on commercial road
vehicles;
– a statement in 7.12 is required concerning cleaning of the appliance with a water jet;
– the replacement of 22.103, 22.104 and 22.105 allows interlock systems with at least one
concealed door interlock as well as alternative interlock systems without concealed door
interlock;

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.
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 may 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 and generic standards 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. For
example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 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 which 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.

HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES – SAFETY –
Part 2-90: Particular requirements for commercial microwave ovens
1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with:
• the safety of microwave ovens with a cavity door intended for commercial use, their rated
voltage being not more than 250 V for single-phase appliances connected between one
phase and neutral and 480 V for other appliances;
• the safety of combination microwave ovens with a cavity door, the requirements for which
are contained in Annex AA;
• the safety of microwave ovens without a cavity door and with transportation means that
are intended for commercial use only, for the heating of food and beverages, the
requirements for which are contained in Annex BB.
Microwave ovens covered by Annex BB have transportation means for moving the load
through the microwave oven. Requirements for tunnel microwave ovens and several types of
microwave vending machines are covered.
This standard also deals with microwave ovens intended to be used on board ships, for which
Annex EE is applicable.
NOTE 101 In Annex BB, a microwave oven without a cavity door and with transportation means is described as a
microwave oven. All clauses of this standard apply to these appliances unless otherwise specified in Annex BB.
This international standard also takes into account ordinary persons having access to the
removing area of the vending machine.
NOTE 102 The appliance may be built into a vending machine, in which case IEC 60335-2-75 may also be
applicable.
NOTE 103 Appliances that use non-electrical energy are within the scope of this standard.
In general, this standard does not take into account
– the use of appliances by young children or infirm persons without supervision;
– playing with the appliance by young children.
This international standard does not take into account the use of a microwave oven without a
cavity door and with transportation means by ordinary persons except in the vicinity of
entrance and exit ports.
NOTE 104 The rationales for particular microwave exposure conditions and measures related to microwave energy
being confined by an open structure are in Annex BB.
NOTE 105 Attention is drawn to the fact that
– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be
necessary;
