This European Standard was approved by CENELEC on 2003-02-01. 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

Foreword
The text of document 61E/405/FDIS, future fourth edition of IEC 60335-2-50, prepared by SC 61E of the
IEC Technical Committee 61, was submitted to the IEC-CENELEC parallel vote and was approved by
CENELEC as EN 60335-2-50 on 2003-02-01.
This European Standard replaces EN 60335-2-50:2000.
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) 2003-11-01
- date on which national standards
conflicting with the EN have to be withdrawn (dow) 2006-02-01
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 electric bains-marie.
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.

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its
