ELECTRIC TOASTERS FOR HOUSEHOLD AND
SIMILAR PURPOSES –
Methods for measuring the performance
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 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 approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60442 has been prepared by subcommittee 59G: Small kitchen
appliances, of IEC technical committee 59: Performance of household electrical appliances.
This second edition cancels and replaces the first edition published in 1973 and amendment 1
(1992), and constitutes a technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
59G/85/FDIS 59G/89/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
Annex A forms an integral part of this standard.

ELECTRIC TOASTERS FOR HOUSEHOLD AND
SIMILAR PURPOSES –
Methods for measuring the performance
1 Scope and object
This International Standard applies to electric toasters for household and similar use.
The purpose of this standard is to state and define the main performance characteristics for
toasters, which are of interest to the user, to describe the standard methods for measuring
these characteristics and to give some guidelines for the evaluation of test results.
Taking into account the low grade of accuracy and repeatability, due to variations in time and
origin of test materials and ingredients and to the influence of the subjective judgement of test
operators, the described test methods may be applied more reliably for comparative testing of
a number of appliances at approximately the same time, in the same laboratory, by the same
operator and with the same utensils, rather than for testing of single appliances in different
laboratories.
This standard is not concerned with safety.
It does not apply to appliances designed exclusively for commercial or industrial use.
2 Normative reference
The following normative document contains provisions which, through reference in this text,
constitute provisions of this International Standard. At the time of publication, the edition
indicated was valid. All normative documents are subject to revision, and parties to agreements
based on this International Standard are encouraged to investigate the possibility of applying
the most recent edition of the normative document indicated below. Members of IEC and ISO
maintain registers of currently valid International Standards.
BS 3999: "Shade chart" Part 5 C. 1983
3 Definitions
For the purpose of this International Standard the following definitions apply:
3.1
radiant toaster
toaster intended for toasting slices of bread by radiant heat. The slices are toasted either on
one side or both sides at a time
NOTE – Radiant toasters may be provided with attachments for heating rolls and for toasting sandwiches.

60442 © IEC:1998 – 9 –
3.2
contact (horizontal) toaster
toaster with one or more heating surfaces which can be brought into contact with slices of
bread
NOTE – Contact (horizontal) toasters are intended for toasting only on one side at a time. Some contact toasters
heat both sides at the same time, particularly when toasting sandwiches.
3.3
roll heating device
device for holding rolls to be heated on the toaster
NOTE – This device can be built in or supplied with the toaster.
3.4
toasting control device
device that automatically terminates the toasting process
3.5
bread carriage
the part of the toaster that supports the bread and releases it at the end of the toasting process
3.6
browning control range
a certain setting on a scale that can be marked with number, symbols or shades of colour
3.7
toasting chamber
space intended for the loading of the slices of bread
3.8
evenness of browning
the brownness visually determined and averaged over one surface of the toasted slice of bread
in each individual case
3.9
toasting degree
average brownness reached by the slices of bread at the end of the toasting process
3.10
toasting range
range of the toasting degree from the minimum brownness to the maximum brownness
4 General conditions for measurements
Unless otherwise specified, the measurements shall be made under the following conditions:
Ambient temperature: 20 °C ± 5 °C
Electrical supply: the measurements shall be made at rated frequency and at a voltage which is
within ±0,5 % of the rated voltage or the mean of the rated voltage range.
NOTE – If the rated voltage differs from the nominal supply voltage of the country concerned, measurements
carried out at rated voltage may be misleading. Therefore, for comparative testing the voltage used for the tests
should conform to the nominal supply voltage and this should be reported.

Testing room: substantially draught free.
Placing of the appliances: at a distance of a least 30 cm away from walls, on a dull black
painted wooden support.
Unless otherwise specified, toasters with roll heating device or sandwiches d
