(Main)Household and similar electrical appliances - Safety - Part 2-110: Particular requirements for commercial microwave appliances with insertion or contacting applicators
Household and similar electrical appliances - Safety - Part 2-110: Particular requirements for commercial microwave appliances with insertion or contacting applicators
IEC 60335-2-110:2013 deals with the safety of microwave appliances 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. Appliances covered by this standard incorporate an open-ended applicator (as example an overview is given in Figure 103) for treatment of the load. They are divided into three types:
- with insertion applicator, typically for moisture removal by insertion into holes in floors, walls or ceilings (an example is given in Figure 106);
- with large area contacting applicator, typically for drying of floors, walls or ceilings (examples are given in Figure 104 and Figure 105);
- with small area contacting applicator, typically for paint removal and spot-heating (an example is given in Figure 107). Key words: commercial microwave appliance, insertion applicator, contacting applicator
This publication is to be read in conjunction with IEC 60335-1:2010.
Appareils électrodomestiques et analogues - Sécurité - Partie 2-110: Exigences particulières pour les appareils à micro-ondes à usage commercial avec applicateurs par insertion ou par contact
La CEI 60335-2-110:2013 traite de la sécurité des appareils à micro-ondes à usage commercial dont la tension assignée n'est pas supérieure à 250 V pour les appareils monophasés branchés entre phase et neutre et à 480 V pour les autres appareils. Les appareils couverts par la présente norme comportent un applicateur ouvert (comme exemple une vue d'ensemble est donnée à la Figure 103) destiné au traitement de la charge. Il en existe trois types:
- les appareils avec applicateur par insertion, généralement utilisés pour enlever l'humidité et fonctionnant par insertion dans des trous au plancher, au mur ou au plafond (un exemple est donné à la Figure 106);
- les appareils avec applicateur par contact de grande surface, généralement utilisés pour le séchage de planchers, murs ou plafonds (des exemples sont donnés aux Figure 104 et 105);
- les appareils avec applicateur par contact de petite surface, généralement utilisés pour le décapage de peinture et le chauffage par points (un exemple est donné à la Figure 107). Mots-clés: appareil à micro-onde à usage commercial, applicateur par insertion, applicateur par contact
Cette publication doit être lue conjointement avec la CEI 60335-1:2010.

Part 2-110: Particular requirements for commercial
microwave appliances with insertion or contacting applicators
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 consolidated version of the official IEC Standard and its amendment has been
prepared for user convenience.
IEC 60335-2-110 edition 1.1 contains the first edition (2013-09) [documents 61B/477/FDIS
and 61B/483/RVD] and its amendment 1 (2019-10) [documents 61B/613/CDV and 61B/637/
RVC as well as 61B/614/CDV and 61B/638/RVC].
In this Redline version, a vertical line in the margin shows where the technical content
is modified by amendment 1. Additions are in green text, deletions are in strikethrough
red text. A separate Final version with all changes accepted is available in this
publication.
