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.

6 General conditions for measurements
Unless otherwise specified, measurements are made under the following conditions:
Supply voltage:
The heater is supplied at a voltage which gives the rated power input under steady
conditions. If a power input range is marked on the heater, the voltage is that giving the mean
value of the range.
NOTE 1 – Heaters with PTC heating elements are supplied at rated voltage or at the mean value of the rated
voltage range.
+AMD2:2018 CSV © IEC 2018
NOTE 2 – If the results obtained by testing the heater as specified are considered to be misleading due to the
national nominal supply voltage, the heater may also be tested at a power input corresponding to the nominal
voltage of the national supply system.
Adjustment:
Controls to be set by the user are set at the maximum position.
NOTE 3 – The intention is to obtain an energy ratio of 100 %. If this cannot be obtained due to the ambient
temperature thermostat cycling, even at the lowest limit of the test room temperature, this thermostat is short-
circuited or otherwise rendered inoperative.
Test rooms:
The tests of clauses 7, 8, 9, 10, 14, 15 and 16 are carried out in a draught-free room in
which the ambient temperature is maintained at 23 °C ± 2 °C.
The tests of clauses 11, 12 and 13 are carried out in a room where the heat losses can
be adjusted. This room is referred to as a "climatic test room" and an example is given in
annex A.
Positioning of the heater:
For the measurement of clauses 8, 9 and 10, the heater is placed in a corner which consists
of two walls, a floor and, if necessary, a ceiling, at right angles. The corner is made of dull-
black painted plywood having a thickness of approximately 20 mm.
The heater is positioned in the corner as follows:
– Portable fan heaters are placed with the back 150 mm from one of the walls and away from
the other wall.
– Other heaters normally placed on a floor are positioned with their back as near as possible
to one of the walls and away from the other wall. However, portable heaters intended to
emit heat in several directions are moved away from the wall by a distance of 300 mm.
– Heaters normally fixed to a wall are fixed to one of the walls, as near to the other wall and
to the floor as is likely to occur in normal use, unless otherwise stated in the instructions for
installation. A dull-black painted plywood shelf having a thickness of approximately 20 mm
and a depth of 200 mm is fixed over the heater as near as possible to the top of the heater
unless otherwise stated in the instructions.
– Heaters normally fixed to the ceiling are fixed to the ceiling as near to the walls as is likely
to occur in normal use, unless otherwise stated in the instructions for installation.
However, built-in heaters are installed according to the instructions for installation, using dull-
black painted plywood approximately 20 mm thick. The heater is installed as close as possible
to a similar dull-black painted floor or ceiling, unless otherwise stated in the instructions.
7 Dimensions, mass and means of connection to the supply
The overall length, height and depth of the heater, including any knobs, handles and fixing
brackets, are determined.
The dimensions are stated in millimetres, rounded up to the nearest 5 mm.
The mass is stated in kilograms, rounded up to the nearest 0,1 kg.
– 10 – IEC 60675:1994+AMD1:1998
+AMD2:2018 CSV © IEC 2018
The length between the point of entry of the cord to the heater and the entry to the plug or
the end of the outer sheath at the free end of the cord, is determined, unless the heater is
provided with terminals for connection to fixed wiring.
NOTE – It is recorded whether or not a plug is fitted.
The length of the supply cord is stated in metres, rounded down to the nearest 0,05 m, or it is
stated that the heater is for connection to fixed wiring.
8 Temperature rises of air-outlet grilles and external surfaces
The temperature rises of air-outlet grilles of convector heaters and fan heaters are
determined.
The temperature rises of external surfaces are determined except for:
– heaters for mounting at a height above 1,8 m;
– the back of wall-mounted heaters;
– visibly glowing radiant heaters;
NOTE – The surface of radiant heaters through which the heating element is visible is considered to be an external
surface and not an air-outlet grille.
The temperature rises are measured by means of the probe of figure 2. The probe is applied
to the surface with a force of 4 N ± 1 N in such a way that the best possible contact is
ensured.
Air-outlet grilles and their surrounds to a distance of 25 mm from the edge of the outlets are
divided into a minimum number of equal rectangles having sides not exceeding 25 mm in
height and 150 mm in length. The probe is applied to the grille as near to the centre of the
rectangles as possible.
Other surfaces are divided into a minimum number of equal rectangles having sides not
exceeding 150 mm. The probe is applied to the centre of the rectangles.
The temperature rise distribution, the highest and the average temperature rises of the
various parts are stated, rounded to the nearest 1 K.
9 Temperature rises of surfaces surrounding the heater
The temperature rises of surfaces surrounding the heater such as walls, floor, ceiling and shelf
are determined.
The measurements are made by using fine-wire thermocouples having a diameter not
exceeding 0,3 mm, attached to the back of small blackened disks of copper or brass, 15 mm in
diameter and 1 mm thick. The front of the disks are flush with the surface of the board. The
thermocouples are positioned to measure the highest temperature rise of each surface.
The highest temperature rises are stated, rounded to the nearest 1 K.
10 Warming-up time of the heater
The warming-up time of the heater is determined.
The time taken for the heater to attain 90 % of the temperature rise under steady conditions is
measured. The temperature rise of the hottest point of external surfaces or air-outlet grilles,
+AMD2:2018 CSV © IEC 2018
whichever reaches steady conditions first, is used as a reference as long as it is representative
of the temperature rise of the surface.
NOTE – Steady conditions are considered to be reached when the temperature rise within 15 min does not vary
more than 2 K.
The warming-up time is stated to the nearest minute, preceded by "approximately".
11 Stability of room temperature
The amplitude and drift are determined for heaters incorporating an ambient temperature
thermostat.
11.1 Basic method of evaluation
The heater is placed in the test chamber of a climatic test room (see annex A).
The temperature inside the test chamber is measured for three different energy ratios which
are obtained by changing the temperature in the refrigerating chamber, without changing the
setting of the ambient temperature thermostat. The measurements are made when the
average room temperature is stable over a period of five consecutive fluctuations or 2 h,
whichever is shorter.
The first measurement is made with the ambient temperature thermostat set to give a
temperature in the test room between 20 °C and 25 °C at a high energy ratio. The high
energy ratio is (80 ± 5) % but if the ratio is not attainable due to the capacity of the climatic
test room, the highest possible energy ratio is used.
NOTE 1 – If the energy ratio of (80 ± 5) % cannot be attained with a heater belonging to a family, the method
of 11.2 is used instead.
The temperature of the refrigerating chamber is then increased to give an energy ratio of
(50 ± 5) %, The third measurement is made with a low energy ratio. The low energy ratio
is (20 ± 5) %, but if this results in heat-losses less than 150 W, the low energy ratio is that
corresponding to 150 W.
The amplitude is determined for the energy ratio of (50 ± 5) %.
The drift is determined from the average room temperature at the high and low energy
ratios using the following formula:
D= (t − t )×
B A
A− B
where
D is the drift;
t is the average room temperature at the high energy ratio;
A
t is the average room temperature at the low energy ratio;
B
A is the measured value of the high energy ratio;
B is the measured value of the low energy ratio.
NOTE 2 – In the formula, 60 is the difference between the ratios of 80 % and 20 %.
NOTE 3 – If the average room temperature at the energy ratio of 50 % does not fall between t and t , the
A B
formula is not applicable and the maximum difference of the three values is stated as the drift.
The amplitude and the drift are stated to the nearest 0,1 K.
– 12 – IEC 60675:1994+AMD1:1998
+AMD2:2018 CSV © IEC 2018
If the tests are not carried out in a climatic test room complying with annex A, this is stated.
11.2 Method for a family of heaters
The amplitude and drift for a family of heaters may be determined using the following
procedure. Heaters are considered to belong to a family when they have the same basic
construction and have:
– the same dimensions except that the length of the heating element is proportional to the
rated power input;
– the same ambient temperature thermostat;
NOTE – Ambient temperature thermostats are considered to be the same if they have the same type reference,
and for electronic thermostats, the same triac and heat sink if these components influence the sensor.
– the same arrangement for the space containing the ambient temperature thermostat;
– the same construction at the end of the heating element adjacent to the space containing
the ambient temperature thermostat.
If there are more than two heaters in a family within the capacity of the climatic test room,
only the heater having the lowest rated power input and the heater having the highest
rated power input need to be tested. The amplitude and drift for heaters having an
intermediate rated power input are calculated by interpolation between the values found for
the two heaters tested.
If any heater within the family has a rated power input higher than the capacity of the
climatic test room, the amplitude and drift are determined as follows.
The amplitude and drift for the heater having the highest rated power input within the
capacity of the climatic test room are determined as specified in 11.1. A resistive load
located outside the test chamber is then connected in parallel with the heating element of
this heater. The load is such that the total power input is equal to the power input of the
heater having the highest rated power input. The amplitude and drift are determined as
specified in 11.1.
The amplitude and drift for any heater within the family having an intermediate rated
power input are calculated by interpolation between the values determined for the heater
with and without external load.
The amplitude and drift are stated for each of the heaters, rounded to the nearest 0,1 K.
12 Set-back
The set-back is determined for heaters incorporating a set-back device.
The average room temperature is determined for the high energy ratio as specified in 11.1.
The set-back device is then activated without changing the setting of the ambient
temperature thermostat and the average room temperature is determined again.
The set-back is the difference between the two values of average room temperature. It is
stated, rounded to the nearest 0,5 K.
13 Frost protection temperature
The frost protection temperature is determined for heaters incorporating frost protection
means.
+AMD2:2018 CSV © IEC 2018
The temperature of the refrigerating chamber of the climatic test room is maintained at the
value attained when the heater was tested at the high energy ratio as specified in 11.1.
The frost protection means is then activated and the room temperature is measured when
steady conditions are established.
NOTE 1 – If the ambient temperature thermostat does not cycle under this condition, the temperature in the
refrigeration chamber is reduced.
The minimum room temperature is stated, rounded down to the nearest 1 °C.
NOTE 2 – The heater is not considered to have frost protection means if the value is beyond 7 °C ± 3 °C.
14 Inrush current
The inrush current is determined.
The current is measured from the time the heater is switched on until it stabilizes.
The heater is considered to have an inrush current if the maximum value after 10 s is higher
than 1,1 times the stable value.
The inrush current is stated, rounded to the nearest ampere.
15 Effect of radiant heat
The effect of radiant heat is determined for panel heaters and radiant heaters.
A dull-black painted plywood board approximately 20 mm thick, having a width of 1,5 m and
a height of 1 m, is positioned vertically on the floor symmetrically in front of the heater at a
distance of 1m.
Thermocouples as specified in clause 9, except that the discs are not blackened, are arranged
on the board, the distance between adjacent thermocouples being not more than 10 cm.
A similar thermocouple protected against heat radiation is placed behind the board at a
horizontal distance of 0,2 m from the centre.
NOTE – Protection can be achieved by placing the thermocouple in a thin wall reflecting cylinder which is open at
both ends.
The temperatures are measured when steady conditions are established. The temperature
rises are calculated, being the difference between the arithmetic average temperature of the
thermocouples on the board and the protected thermocouple.
The following temperatures rises of the board are stated rounded to the nearest 1 K:
NOTE 1 – During the period where measurements are made, the ambient temperature of the room is to be
maintained within 0,5 K.
– the temperature rise distribution;
– the highest and lowest temperature rises;
– the average temperature rise;
– the lowest and the average temperature rise of the central part of the board over a width of
0,5 m.
NOTE 2 – The board may be positioned to measure the effect of radiant heat from the sides of the heater.
NOTE 3 – If the top of the heater is higher than 1 m above the floor, the board may be positioned vertically.
NOTE 4 – The test is not suitable for heaters for mounting at a height above 1,8 m.
– 14 – IEC 60675:1994+AMD1:1998
+AMD2:2018 CSV © IEC 2018
16 Measurement of the usable power
The measurement of usable power is determined for heaters which cycle during the test of
clause 10.
The heater is operated until steady conditions are established. The energy consumed during
the subsequent 10 complete cycles of operation of the thermostat is measured. If necessary,
the test is continued for further complete cycles to ensure that the time during which the energy
measurement is carried out is at least 1 h.
NOTE – Any ambient temperature thermostat is short-circuited.
The usable power is determined by dividing the energy consumed by the time taken and is
stated if less than 90 % of the rated power input.
17 Verification of the maximum room temperature promoted by the
manufacturer
Only if promoted by the manufacturer and underlined by values, is the maximum room
temperature achievable for direct-acting room heaters with a built-in ambient temperature
thermostat determined under the conditions of low-heat requirement in the climatic test room
in accordance with Annex A.
The temperature of the refrigerating chamber is set to give an energy ratio of 80 % ± 5 %.
If the ambient temperature thermostat is not cycling, the air exchange between the
refrigerating chamber and the test chamber, and, if necessary, the cooling unit of the
refrigerating chamber, can be stopped.
The heater is operated at maximum settings of heating capability and ambient temperature
thermostat until steady conditions are established. Portable heaters are placed as near as
possible to one of the walls and fixed heaters are installed, both according to the
manufacturer's instructions.
The temperature of the test chamber is measured in accordance with Annex A and stated
rounded to the nearest 1 K.

Annex A
(normative)
Climatic test room
The climatic test room consists of a test chamber for simulating the indoor temperature and a
refrigerating chamber for simulating the outdoor temperature. The chambers are separated by
a wall, referred to as the exterior wall, as shown in figure A.1.
The heat demand in the test chamber is created by changing the temperature in the
3 3
refrigerating chamber. The test chamber has a volume between 30 m and 40 m , a length
between 3 m and 4 m, a width between 3 m and 4 m and a height between 2,4 m and 2,6 m.
In the exterior wall, there is a window of at least 3 m × 1,5 m having a coefficient of thermal
conductance not more than 3 W/m K. The wall under the window has a height of at least 0,8 m
and has a coefficient of thermal conductance not more than 0,5 W/m K. The remainder of the
exterior wall has a coefficient of thermal conductance not more than 1,0 W/m K. The other
walls, the floor and the ceiling have a coefficient of thermal conductance not more than
0,6 W/m K.
Cold air in the test chamber is supplied from the refrigerating chamber through two inlets
placed symmetrically above the window. The air is returned to the refrigerating chamber at the
upper corners of the exterior wall by means of ducting. The extraction point in the test chamber
is on the wall opposite to the exterior wall at a height not more than 0,4 m above the floor.
The air exchange between the refrigerating chamber and the test chamber is approximately
one test chamber volume per hour.
The refrigerating chamber is to be capable of creating a heat-loss through the exterior wall of
at least 1 000 W.
The ambient temperature surrounding the climatic test room is to be within 2 °C of the mean
temperature of the test chamber when setting the ambient temperature thermostat in 11.1.
The heater is placed in the test chamber against the wall, below the centre of the window,
according to the instructions. If the heater is too high to be placed below the window, it is
placed on one of the adjacent walls with its centre at a distance of 2 m from the exterior wall,
so that the side of the heater containing the ambient temperature thermostat is closer to the
exterior wall. No heat source other than the appliance under test is to be in the test room.
The temperature of the test chamber is measured by means of a thermocouple placed inside a
thin-wall black globe having a diameter of approximately 10 cm. The globe is located centrally
at a distance of 2 m from the exterior wall and at a height of 1,2 m above the floor. The
recording instrument is located outside the test chamber.

HOUSEHOLD ELECTRIC DIRECT-ACTING ROOM HEATERS –
METHODS FOR MEASURING 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 60675 has been prepared by subcommittee 59C: Heating
appliances, of IEC technical committee 59: Performance of household electrical appliances.
This consolidated version of IEC 60675 consists of the second edition (1994) [documents
59C/51/FDIS and 59C/54/RVD] and its amendment 1 (1998) [documents 59C/81/FDIS and
59C/84/RVD].
The technical content is therefore identical to the base edition and its amendment and has
been prepared for user convenience.
It bears the edition number 2.1
A vertical line in the margin shows where the base publication has been modified by
amendment 1.
Annex A forms an integral part of this standard.
Annexes B to D are for information only.
In this standard, the following print types are used:
– test specifications: in italic type
notes: in small roman type
–
– other texts: in roman type
Words in bold in the text are defined in clause 3.

6 Conditions générales d'exécution des mesures
Sauf spécification contraire, les mesures sont faites dans les conditions suivantes:
Tension d'alimentation:
L'appareil est alimenté à une tension permettant d'obtenir la puissance assignée dans les
conditions de régime. Si une plage de puissance est indiquée sur l'appareil, la tension est
celle permettant d'obtenir la puissance moyenne.
NOTE 1 – Les appareils comportant des éléments chauffants du type CTP sont alimentés à la tension assignée ou
la valeur moyenne de la plage de tensions assignées.
NOTE 2 – Si les résultats obtenus en essayant l'appareil comme spécifié sont considérés comme pouvant être
erronés du fait de la tension nominale du réseau national de distribution, l'appareil peut également être essayé à la
puissance correspondant à la tension nominale du réseau national.
Réglage:
Les dispositifs de commande à disposition de l'usager sont placés sur leur position maximale.
NOTE 3 – L'intention est d'obtenir un rapport d'énergie de 100 %. Si ce rapport ne peut pas être obtenu du fait
que le thermostat d'ambiance se déclenche, même à la limite la plus basse de la température du local d'essai, ce
thermostat est court-circuité ou rendu inopérant d'une autre façon.
Locaux d'essai:
Les essais des articles 7, 8, 9, 10, 14, 15 et 16 sont effectués dans un local exempt de
courants d'air et dont la température ambiante est maintenue à 23 °C ± 2 °C.
Les essais des articles 11, 12 et 13 sont effectués dans un local permettant de régler les
déperditions de chaleur. Ce local est appelé «enceinte climatique» et un exemple en est donné
à l'annexe A.
Disposition de l'appareil:
Pour les mesures des articles 8, 9 et 10, l'appareil est placé dans un coin d'essai constitué de
deux parois à angle droit, d'un plancher et, si nécessaire, d'un plafond. Ce coin est en contre-
plaqué peint en noir mat de 20 mm d'épaisseur environ.
L'appareil est disposé dans le coin d'essai comme suit:
– Les mobiles sont disposés avec l'arrière à 150 mm de l'une des
appareils soufflants
parois et éloignés de l'autre.
– Les autres appareils normalement placés sur le sol sont disposés avec la face arrière
placée le plus près possible de l'une des parois et éloignés de l'autre paroi. Toutefois, les
appareils mobiles prévus pour émettre de la chaleur dans plusieurs directions sont écartés
du mur d'une distance de 300 mm.

NOTE 12 – This measurement is suitable for all heaters.
6 General conditions for measurements
Unless otherwise specified, measurements are made under the following conditions:
Supply voltage:
The heater is supplied at a voltage which gives the rated power input under steady
conditions. If a power input range is marked on the heater, the voltage is that giving the mean
value of the range.
NOTE 1 – Heaters with PTC heating elements are supplied at rated voltage or at the mean value of the rated
voltage range.
NOTE 2 – If the results obtained by testing the heater as specified are considered to be misleading due to the
national nominal supply voltage, the heater may also be tested at a power input corresponding to the nominal
voltage of the national supply system.
Adjustment:
Controls to be set by the user are set at the maximum position.
NOTE 3 – The intention is to obtain an energy ratio of 100 %. If this cannot be obtained due to the ambient
temperature thermostat cycling, even at the lowest limit of the test room temperature, this thermostat is short-
circuited or otherwise rendered inoperative.
Test rooms:
The tests of clauses 7, 8, 9, 10, 14, 15 and 16 are carried out in a draught-free room in
which the ambient temperature is maintained at 23 °C ± 2 °C.
The tests of clauses 11, 12 and 13 are carried out in a room where the heat losses can
be adjusted. This room is referred to as a "climatic test room" and an example is given in
annex A.
Positioning of the heater:
For the measurement of clauses 8, 9 and 10, the heater is placed in a corner which consists
of two walls, a floor and, if necessary, a ceiling, at right angles. The corner is made of dull-
black painted plywood having a thickness of approximately 20 mm.
The heater is positioned in the corner as follows:
– Portable fan heaters are placed with the back 150 mm from one of the walls and away from
the other wall.
– Other heaters normally placed on a floor are positioned with their back as near as possible
to one of the walls and away from the other wall. However, portable heaters intended to
emit heat in several directions are moved away from the wall by a distance of 300 mm.
