Table 1 – Measurements of various types of irons
Amend the heading of the fourth column of Table 1 to read:
Thermostatic steam irons and vented steam irons with a motor pump.

Page 10
5 General conditions for measurements
Add, on page 11, the following new subclause:
5.10 Irons with additives
If the manufacturer requires the use of specific additives as an integral part of the functioning
of the iron, then the iron shall be tested using the additives.

Page 16

9.2 Measurements of steaming time, steaming rate and water emission rate
9.2.1 For vented steam irons

Add, on page 17, after the 3 paragraph, the following sentence:
For vented steam irons with motor pump, the motor pump may be controlled by external
means during the test.
Page 22
11 Measurement of input power and energy consumption
11.2 Measurement of energy consumption
Replace “Under consideration” by the following:
11.2.1 Preparation of the test cloth
Samples of textile material composed of cotton are prepared according to 10.1.1. The test
cloth is conditioned according to 10.1.2.
The samples have dimensions of 600 mm x 1 500 mm with the sides parallel to the warp. The
samples are cut using pinking scissors, and maintained in a dry atmosphere at a temperature
of 20 °C ± 5 °C for at least 48 h.

– 4 – IEC 60311:2002/AMD1:2005
© IEC 2005
Each sample is subdivided into 5 strips of 300 mm (not cut, only marked with a pen).
NOTE Dimensions of standardized ironing-board: 650 mm x 350 mm.
11.2.2 Measurement of the energy consumed during heating-up operation
11.2.2.1 For dry irons
The iron is connected to a suitable energy meter, capable of measuring to an accuracy of
±1 %. The thermostat, if any, is set so that the mean sole-plate temperature of 190 °C ±
10 °C is reached.
The energy consumed during this heating-up interval is recorded as E in kWh.
11.2.2.2 For vented steam irons
The iron is connected to a suitable energy meter, capable of measuring to an accuracy of
±1 %. The water reservoir is filled with distilled water having a temperature of 20 °C ± 2 °C up
to the capacity specified by the manufacturer and then the iron is placed on its stand or in its
upright position. The thermostat is set so that the mean sole-plate temperature of
190 °C ± 10 °C is reached.
For irons with a separate water reservoir, the reservoir is filled up to the capacity specified by
the manufacturer.
The energy consumed during this heating-up interval is recorded as E in kWh.
11.2.2.3 For pressurized steam irons
The iron is connected to a suitable energy meter, capable of measuring to an accuracy of
±1 %. The boiler is filled with distilled water having a temperature of 20 °C ± 2 °C up to the
rated capacity and then placed on its stand.
The thermostat of the iron is set so that the mean sole-plate temperature of 190 °C ± 10 °C is
reached, any setting of the boiler shall be set at the maximum.
The energy consumed during this heating-up interval is recorded as E in kWh.
11.2.3 Measuring of energy consumed during an ironing operation
NOTE The results of energy consumption test should only be used in conjunction with assessment of smoothing
according to Clause 10.
11.2.3.1 For all irons
For vented and for pressurized steam irons the steaming regulator, if any, is set at the
maximum setting.
The iron is connected to a suitable energy meter, capable of measuring to an accuracy of
±1 %.
The test cloth with dimensions of 600 mm x 1 500 mm and marked according to 11.2.1 is
placed on the ironing board, see Annex B.

© IEC 2005
The first marked strip of the cloth is ironed for 20 s (in case of pressurized steam irons 5 s
with steam and 15 s without steam), a break of 10 s follows (one cycle). This procedure is
repeated with the next 5 strips and then started again from the beginning, with the same cloth.
This procedure is now continued for exactly 10 min.
The energy used for this operation is recorded as E in kWh.
11.2.3.2 Calculation of the total energy consumed for the ironing process
The energy consumption for the iron is reported as the energy consumed during one hour of
the ironing process plus the energy consumption during heat-up time, in kWh.
The energy consumed in one hour is then 6 times the value measured after 10 min., i.e. E =
6 x E kWh.
The total energy consumed during an ironing process is therefore:
E = E + E kWh
total 1 3
Add, on page 23, the following new subclause:
11.3 Ironing efficiency
(Under consideration)
Page 26
14 Determination of total steaming time for hard water
rd
Add the following sentence after the 3 paragraph on page 27:
For vented steam irons with motor pump, the motor pump has to be switched off in the
upright position.
Page 28
16 Information at the point of sale
In the first sentence, change “should” to “shall”, and add “if applicable” at the end of the
sentence.
Replace the existing items by the following:
a) type of iron (dry iron, steam iron, vented steam iron with motor pump, irons with steam
generator/boiler, etc.)
b) voltage/voltage range (V);
c) frequency (Hz);
d) power input (W);
e) cord length (m);
f) weight (g) (the iron without supply cord);

– 6 – IEC 60311:2002/AMD1:2005

g) weight (g) (the whole appliance, e.g. including supply cord, water container/boiler);
h) sole-plate material and coating;
i) scratch resistance (excellent, good, poor);
j) water to be used (tap water up to a hardness as declared by the manufacturer,
dematerialized water);
k) use of specific additives
l) steaming rate (g/min)
m) shot of steam, (g/shot)
n) additional functions/features, for example:
− spray;
− anti-scale device;
− drip-stop;
− auto-shut off;
− detachable water tank.
