HOUSEHOLD MICROWAVE OVENS –
METHODS FOR MEASURING PERFORMANCE


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.
International Standard IEC 60705 has been prepared by subcommittee 59K: Ovens and
microwave ovens, cooking ranges and similar appliances, of IEC technical committee 59:
Performance of household and similar electrical appliances.
This fourth edition cancels and replaces the third edition published in 1999, its amendment 1
(2004) and its amendment 2 (2006), and constitutes a technical revision. The main changes
from the previous edition are as follows:
– the definition of rounding is given in 3.5;
– the usable volume and the overall volume are respectively determined in 7.2 and 7.3.

6 General conditions for measurements
6.1 General
Unless otherwise specified, the measurements are made under the following conditions.
When a metal turn table or any metal accessories are provided and used for the
measurements, the load position and the corresponding shape of the metal turn table or any
metal accessories shall be reported, together with the test results.
NOTE The positioning influences the repeatability of the test results.
If numbers have to be rounded, they shall be rounded to the nearest 50 W according to ISO
80000-1:2009, Annex B.3 Rule B. If the rounding takes place to the right of the comma, the
omitted places shall not be filled with Zeros.
6.2 Supply voltage
The appliance is supplied at rated voltage ±1 %. If the appliance has a rated voltage range,
the tests are carried out at the nominal voltage of the country where the appliance is intended
to be used. This voltage is stated in the report.
NOTE The supply voltage should be essentially sinusoidal. Results of the tests may otherwise be affected.
6.3 Test room
The tests are carried out in a substantially draught-free room in which the ambient temperature
is maintained at 20 °C ± 5 °C.
6.4 Water
Potable water is used for the tests.
6.5 Initial condition of the oven
At the beginning of each test,
– the temperatures of the magnetron and the power supply shall be within 5 K of the ambient
temperature, or
– the oven has not been operated for a period of at least 6 h. However, this period may be
reduced if it can be demonstrated that the microwave power output, as determined in
Clause 8, is available earlier.
NOTE Forced cooling may be used to assist in reducing the oven temperature.
6.6 Control setting
The tests are carried out with the controls set to give the highest power output. Unless
otherwise specified the measurements are made with boost function, if available.
7 Dimensions and volume
7.1 External dimensions
The overall height, width and depth of the appliance, excluding any knobs and handles on the
front surface, are measured. The depth is also measured with the door fully open. The

7.2 Usable internal dimensions and usable volume
7.2.1 General
Removable items specified in the user instructions to be not essential for the operation of the
appliance in the manner for which it is intended shall be removed before measurement is
carried out.
The measurement of the usable oven volume is to be carried out at ambient temperature.
The height, width and depth of the usable volume in the cavity shall be measured according to
7.2.2 – 7.2.4.
For verification purposes a gauge, as shown in Figure 2a, shall be used to determine all of the
three dimensions. The gauge shall be used without appreciable force.
Dimensions are stated in millimetres.
Microwave ovens having a usable height of less than 120 mm are disregarded.
