INTRODUCTION to Amendment 1
This amendment includes the following significant technical changes:
– the usable volume is renamed to calculated volume and the measurement method for the
calculated volume is revised (see 7.2), which is in accordance with IEC 60350-1;
– new definitions for microwave function, combination microwave function, set to off
mode, set to standby mode, cooling down period and food support in Clause 3;
– a method for measuring the energy consumption of the microwave function in Clause 14;
– more precise requirements for instruments and measurements in Table 2;
– additional product specific requirements for measuring the energy consumption of low
power modes in Clause 15;
– a method for measuring the energy consumption for the cooling down period in Annex F
(informative).

FOREWORD
Add, after the existing paragraph starting with "Words in bold…", the following new paragraph:
This standard contains an attached file in the form of an Excel® 97-2003 data sheet
program. This file is intended to be used as a complement and does not form an integral part
of the standard.
1 Scope
Replace, in Note 1, the dashed item “ovens which cannot accept a load having a diameter of
≥200 m” with the following dashed item:
– microwave ovens which cannot accept a load having a diameter of ≥ 200 mm or a height of ≥ 120 mm;
2 Normative references
Add the following references:
IEC 60350-1:2011, Household electric cooking appliances – Part 1: Ranges, ovens, steam
ovens and grills – Methods for measuring performance
IEC 60584-2, Thermocouples – Part 2: Tolerances
IEC 62301:2011, Household electrical appliances – Measurement of standby power
3 Terms and definitions
3.1
microwave oven
Delete Note 1 and renumber Note 2 as Note 1.
3.2
combination microwave oven
Add the following new note:
NOTE Energy transfer by steam is included in the term thermal heat.
Add, after 3.4, the following new terms and definitions:
3.5
microwave function
heat transfer exclusively by electromagnetic energy in the ISM frequency band of 2 450 MHz
3.6
combination microwave function
heat transfer by electromagnetic energy simultaneously or sequentially with thermal heat
NOTE Thermal heat can be a conventional heating function, a forced air circulation function, a hot steam function
or steam function. These functions are defined in 3.12 to 3.15 of IEC 60350-1:2011.

3.7
set to off mode
action where the product is switched off using appliance controls or switches that are
accessible and intended for operation by the user during normal use to attain the lowest
power consumption that may persist for an indefinite time while connected to a main power
source and used in accordance with the manufacturer’s instructions
NOTE 1 All actions required to set to off mode like for example empty the water tank, remove food, close the
door, etc. have to be taken.
NOTE 2 See 3.5 of IEC 62301:2011 for the definition of "off mode".
3.8
set to standby mode
action where the product is switched to standby using appliance controls or switches that are
accessible and intended for operation by the user during normal use to attain the lowest
power consumption that may persist for an indefinite time while connected to a main power
source and used in accordance with the manufacturer’s instructions
NOTE See 3.6 of IEC 62301:2011 for the definition of "standby mode".
3.9
cooling down period
unstable condition persisting after completion of the active mode and the appliance is set to
off mode where the power consumption may change without any intervention by the user
3.10
food support
horizontal support in the cavity on which the load is placed
NOTE If the appliance is fitted with a turntable, the turntable is the food support. The food support can also be
a shelf or a reciprocating tray. If recommended by manufacturer’s instruction also the cavity bottom can be the
food support.
4.1 According to type
Add, after the second dashed item, before the sentence “The type of oven shall be stated in
the report” the following new paragraphs and new note:
The manufacturers shall define the primary cooking function of the appliance, microwave
function or thermal heat. The primary cooking function has to be measured with an existing
method according to energy consumption.
If the primary cooking function is declared as a microwave function IEC 60705 shall be
applied for energy consumption measurement. If the primary cooking function is declared as a
thermal heat IEC 60350-1 shall be applied for energy consumption measurement.
NOTE There is currently no measurement method for the energy consumption for grilling and steam functions.
4.2 According to characteristics
Replace the existing second dashed item by the following new dashed items:
– Dimensions of shelves
– Moved food support, e.g. reciprocating tray, turntable
– Possible thermal heating modes (grilling, hot air, steam function etc.).
5 List of measurements

Except for the tests of 11.1, these tests are also applicable to combination microwave ovens when operated
in the microwave only mode.
Add, under Table 1, the following new paragraph:
The methods described in Clauses 8 and 14 are only applicable for appliances with
microwave function. If a combination microwave oven does not provide a microwave
function the tests are not applicable. The energy consumption measurement cannot be
carried out with combined microwave function.
6.1 General
Replace the existing second paragraph by the following:
When a metal food support is provided and used for the measurements, the load position
and the corresponding shape of the metal food support shall be reported.
If not otherwise specified the food support is placed in the cavity in its lowest position.
