This European Standard was approved by CENELEC on 2006-03-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Cyprus, the Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
Sweden, Switzerland and the United Kingdom.

Foreword
The text of document 61B/306/FDIS, future edition 3 of IEC 60335-2-90, prepared by SC 61B of the IEC
Technical Committee 61, was submitted to the IEC-CENELEC parallel vote and was approved by
CENELEC as EN 60335-2-90 on 2006-03-01.
This European Standard replaces EN 60335-2-90:2002 + A1:2003.
Changes compared to EN 60335-2-90:2002 concern requirements for 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 following dates are applicable:
- latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2006-12-01
- date on which national standards
conflicting with the EN have to be withdrawn (dow) 2009-03-01
This part 2 has to be used in conjunction with EN 60335-1, Household and similar electrical appliances –
Safety – Part 1: General requirements. It was established on the basis of the 2002 edition of that standard.
Amendments and revisions of Part 1 have also to be taken into account and the dates when such
changes become applicable will be stated in the relevant amendment or revision of Part 1.
This part 2 supplements or modifies the corresponding clauses of EN 60335-1, so as to convert it into the
European Standard: Safety requirements for commercial microwave ovens.
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 of
Part 1 is to be adapted accordingly.
NOTE 1 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.;
- subclauses, notes and annexes that are additional to those in the IEC standard are prefixed with the letter Z.
NOTE 2 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.
There are no special national conditions causing a deviation from this European Standard, other than
those listed in Annex ZA to EN 60335-1.
There are no national deviations from this European Standard, other than those listed in Annex ZB to
EN 60335-1.

Introduction
p Add:
An investigation by CENELEC TC 61 has shown that all risks from products within the scope of this
standard are fully covered by the Low Voltage Directive, 73/23/EEC. For products having mechanical
moving parts, a risk assessment in accordance with the Machinery Directive, 98/37/EC, has shown that
the risks are mainly of electrical origin and consequently this directive is not applicable. However, the
relevant essential safety requirements of the Machinery Directive are covered by this standard together
with the principal objectives of the Low Voltage Directive.
