are inaccessible to a 75 mm diameter probe having a hemispherical end applied with a force not
exceeding 1N;
— the rear surface of appliances where these surfaces are inaccessible to a 75 mm diameter probe
having a hemispherical end applied with a force not exceeding 1N.

— for other appliances 3,5 mA or 1 mA per kW rated power input of the appliance with no maximum,
whichever is higher
8 Modification to Clause 15, “Moisture resistance”
15.2 Replace the third paragraph starting with” For all appliances, 0,5 l…” up to “… a period of 5 min” by the
following:
For all appliances, 0,5 l of the solution is rapidly poured over the top of the appliance, so that the spillage solution
flows over the surfaces of the appliance that incorporate controls, the controls being placed in the on position.
The controls are then operated through their working range, this operation being repeated after a period of 5
min.
For appliances having a working surface, the test is repeated with the appliance tilted at an angle of 2° in relation
to the position of normal use in the direction which is likely to be the most unfavourable.
The lid of top loading appliances is considered as a working surface if it is flat enough to put something on.
9 Modification to Clause 16, “Leakage current and electric strength”
16.2 Add in the modification in the first paragraph the word “combined” before “appliances”.

The running overload test is carried out on appliances that have overload protective devices incorporating
electronic circuits to protect the windings of the drum motor. However, the test is not carried out if the
protective device senses the winding temperature directly.
NOTE 101 Measuring winding resistance or winding current is not directly measuring the winding temperature.
19.101 Delete the sentence starting with “Care should to be taken…”
11 Modification to Clause 20, “Stability and mechanical hazards”
20.101 Replace the value “50 mm” with “75 mm”:
Add the following after the second paragraph:
If compliance relies on the operation of an electronic circuit, the test is repeated under the following conditions
applied separately:
— the fault conditions in a) to g) of 19.11.2 are applied one at a time to the electronic circuit;
— the electromagnetic phenomena tests of 19.11.4.2 and 19.11.4.5 are applied to the appliance.
The drum motor shall not start.
If the electronic circuit is programmable, the software shall contain measures to control the fault/error
conditions specified in Table R.1 and is evaluated in accordance with the relevant requirements of Annex R.
20.102 Replace in the paragraph starting with “The force…” the word “may” with “can”.
20.103 Add in the first paragraph after “built-in appliances”: “or fixed appliances.”
12 Modification to Clause 22, “Construction”
22.103 In the sentence starting with “Each appliance…”, add the following at the end “and then together.”

22.116 Steam generators shall be vented to the atmosphere. The aperture shall be at least 5 mm in diameter
or at least 20 mm in area with a minimum dimension of 3 mm.
Compliance is checked by inspection and by measurement.
22.117 Appliances with a steam generator shall be constructed in such a way that there is no spillage of water
or sudden jets of steam or hot water likely to expose the user to a hazard when the appliance is used in
accordance with the instructions.
If jets of steam or liquids are emitted through protective devices, the electrical insulation shall not be affected
or the user exposed to a hazard.
Compliance is checked by inspection during the tests of Clause 11 and Clause 19.
22.118 For appliances that are controlled by programmable electronic circuits that limit the number of heating
elements and motors from being energized at the same time, simultaneous activation of any combination of
heating elements and motors shall not render the appliance unsafe.
Compliance is checked by the following test:
— the fault/error conditions specified in Table R.1 are applied and evaluated in accordance with the relevant
requirements of Annex R; or
— the appliance is operated under the conditions of Clause 11 while being supplied at rated voltage, the
programmable electronic circuits being modified to allow simultaneous activation of all heaters and
motors under their control.
Under these conditions, compliance with 19.13 shall be fulfilled
22.119
Noise reduction is an integral part of the design process and shall be achieved by particularly applying measures
at source to control noise, see for example EN ISO 11688-1:2009. The success of the applied noise reduction
measures is assessed based on the actual noise emission values in relation to other machines of the same type
with comparable non-acoustical technical data.
Compliance is checked by the noise test code in Annex DD
13 Modification to Clause 24, “Components”
