Household electric cooking appliances - Part 1: Ranges, ovens, steam ovens and grills - Methods for measuring performance (IEC 60350-1:2011, modified + corrigendum Feb. 2012)
This part of IEC 60350 specifies methods for measuring the performance of electric cooking ranges, ovens, steam ovens, and grills for household use. The ovens covered by this standard may be with or without microwave function. Manufacturers should 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 in the instruction manual as a microwave function, IEC 60705 is applied for energy consumption measurement. If the primary cooking function is declared as a thermal heat, then IEC 60350-1 is applied for energy consumption measurement.

La CEI 60350-1:2011 définit des méthodes de mesure de l'aptitude à la fonction des cuisinières, des fours, des fours à vapeurs et des grils à usage domestique. Les fours couverts par la présente norme peuvent disposer ou non d'une fonction micro-ondes. La présente norme définit les principales caractéristiques d'aptitude à la fonction des appareils concernés qui intéressent le consommateur et décrit les méthodes pour la vérification de ces caractéristiques. La présente norme ne spécifie pas les exigences d'aptitude à la fonction. Cette première édition de la CEI 60350-1 est liée à la CEI 60350:1999 qui doit être séparée en deux parties: une partie consacrée aux cuisinières, aux fours et aux fours à vapeur, et l'autre aux tables de cuisson. La présente partie 1 de la CEI 60350 traite des cuisinières, des fours, des fours à vapeur et des grils, et la CEI 60350-2 traite des tables de cuisson. Le contenu du corrigendum de février 2012 a été pris en considération dans cet exemplaire.

Ta del standarda IEC 60350 določa metode za merjenje funkcionalnosti električnih vgradnih štedilnikov, pečic, parnih pečic in žarov za uporabo v gospodinjstvu. Pečice, ki jih zajema ta standard, lahko vključujejo mikrovalovno funkcijo ali ne. Proizvajalci morajo določiti primarno funkcijo kuhanja naprave – mikrovalovna ali toplotna funkcija. Primarno funkcijo kuhanja je treba izmeriti z obstoječo metodo glede na porabo energije. Če je primarna funkcija kuhanja opredeljena v navodilih za uporabo kot mikrovalovna funkcija, se za merjenje porabe energije uporablja standard IEC 60705. Če je primarna funkcija kuhanja opredeljena kot toplotna funkcija, se za merjenje porabe energije uporablja standard IEC 60350-1.

12 Consumption measurement of low power modes
In addition to EN 50564, the following requirements are given.
For an appliance composed of a combination of separate units which may consist of one of a variety of
different hobs and one of a variety of different ovens, the recommended combination as declared in the
manufacturer’s instruction is used for the test.
---------------------- Page: 7 ----------------------
SIST EN 60350-1:2013
EN 60350-1:2013 - 6 -
If appliance A (e.g. hob) can only be operated combined with appliance B (e.g. oven), first the low power
mode for appliance B without appliance A is measured and noted. Afterwards the low power mode for the
appliance B combined with the appliance A is measured. The low power consumption of appliance A is
calculated by the difference between these two measurements.
When preparing the test report for a device composed of a combination of separate units, the
combination of types of main powered parts (hobs, ovens, grills, warming plates, griddles etc.) used for
the measurement shall be recorded. The consumption of low power modes shall be noted for each unit A
and B separately.
NOTE The measurement procedure for energy consumption of hobs is described in EN 60350-2.
When testing appliances that are fitted with a clock, the clock shall be adjusted to the correct time and
date as specified in the instructions.
In case energy consumption is influenced by continuous changing displayed time of a clock, a
measurement period of 24 h is necessary. The average value from this measurement is noted.
If the appliance has an ambient light sensor, two illuminance levels in accordance to EN 50564 shall be
measured during the 24 h period, each illuminance level for 12 h.
If an option is provided to the user to switch off the display, both the switched on and switched off mode
are to be tested and reported.

The measurement shall be started by setting the appliance to off mode. The brick is removed and the
door shall be closed after (30 ± 2) s. The measurement of the low power energy consumption is started
immediately when the appliance is set to off mode.
If the appliance doesn´t offer an off mode it is set to standby mode.
The measurement is stopped after 60 min ± 1 min independent if the ventilation stops automatically.
The energy consumption for the cooling down period W is noted in Wh for each heating mode according

to Table 1.
Ensure that the following conditions remain relevant for the duration of the measurement:
• connected to mains power for the duration of the test;
• no network is connected to the product.
ZB.4 Measurement uncertainty – Energy consumption for the cooling down period
The energy consumption for the cooling down period determined according to ZB.3 shall not be greater
than the value declared by the manufacturer plus 15 %.
If the result of the test carried out on the first appliance is greater than the declared value plus 15 %, the
test shall be carried out on a further three appliances, which shall be randomly selected from the market.
The arithmetical mean of the values of these three appliances shall not be greater than the declared
value plus 10 %.

Annex ZC
(informative)
Check of applied microwave energy during the measurement according to 7.4
ZC.1 General
Heating up the brick according to 7.4 shall only be done with thermal heating. It is not allowed to switch
on a magnetron even not for a short period.
The sophisticated method to check a possible applied microwave energy during the energy consumption
measurement according to 7.1 is to proof if the magnetron is switched on and off. Depending on the
design of the appliances it is not always possible to determine clearly if microwave energy is switched on
during the long lasting heating up process. Therefore following method can be used in a pre-test.
ZC.2 Procedure
A filament lamp with a rated current of 12 mA and rated voltage less than 6 V with bended connecting
wires is used. The length of the wires are approximately half of the wave length of the microwave so the
current distribution is maximum in the middle where the filament of the lamp is (see Figure ZC.1).
Key
c connecting wire
x in the range of 50 mm to 60 mm
Figure ZC.1 — Filament lamp
The brick is prepared as described in 7.4.2.3 and placed in the oven as described in 7.4.3.1 The filament
lamp is placed on the upper surface of the wet brick. The oven is switched on and operated according to
7.4.3.1 for at least this time which is necessary to have a temperature rise in the brick of 55 K.
Then the oven is switched off and the filament lamp is tested. If microwave energy was applied the
electric field during microwave operation will induce currents much more than 12 mA so the filament will
be damaged. The lamp can be tested with a resistance-test-equipment or with a small tester for LED
lamps. The lamp is put into a socket and the filament will light up if it is not damaged. Otherwise
microwave energy was applied.
