1 Scope
Add the following paragraph:
This standard also deals with the safety of tumble dryers that use a refrigerating system,
incorporating sealed motor-compressors, for drying textile material. These appliances may
use flammable refrigerants. Additional requirements for these appliances are given in
Annex BB.
Replace the second dashed item of Note 103 by the following:
– in many countries, additional requirements are specified by the national health authorities, the national
authorities responsible for the protection of labour, the national water supply authorities, the national
authorities responsible for transportation and the national authorities for buildings.
7 Marking and instructions
Add the following subclause:
7.1 Addition:
The appliance shall be marked with symbol 0790 of IS0 7000 or with the substance of the
following:
Read the instructions
7.6 Delete symbol 5036.
7.12 Replace the second paragraph by the following:
If symbols 5041 of IEC 60417-1 or 0790 of ISO 7000 are used, their meaning shall be
explained.
Add the following:
The instructions shall include the substance of the following:
– Do not dry unwashed items in the tumble dryer.
– Do not dry soiled items in the tumble dryer unless they have been washed.
– Items that have been soiled with substances such as cooking oil, acetone, alcohol, petrol,
kerosene, spot removers, turpentine, waxes and wax removers should be washed in hot
water with and extra amount of detergent before being dried in the tumble dryer.
– Items such as foam rubber (latex foam), shower caps, waterproof textiles, rubber backed
articles and clothes or pillows fitted with foam rubber pads should not be dried in the
tumble dryer.
– Fabric softeners, or similar products, should be used as specified by the fabric softeners
instructions.
– The final part of a tumble dryer cycle occurs without heat (cool down cycle) to ensure that
the items are left at a temperature that ensures that the items will not be damaged. Never
stop a tumble dryer before the end of the drying cycle unless all items are quickly
removed and spread out so that the heat is dissipated.
7.12.1 Delete the first dashed item of the first paragraph, including the bullets and Note 101.

7.14 Replace the requirement in the addition by the following:

60335-2-11/Amend. 2/Ed 6.0/CDV © IEC 4

Add the following subclause:
7.15 Addition:
Symbol 0790 of IS0 7000, or the marking “Read the instructions”, shall be readily visible when
the appliance is installed as in normal use.
7.101 Replace the text by “Void”.
7.102 Replace the Note by the following:
NOTE This symbol is a warning sign and the rules of ISO 3864-1 apply.
15 Moisture resistance
15.1 Delete the addition to this subclause.
22 Construction
22.103 Replace the text by “Void”.
Add the following new subclause:

cycle.
Compliance is checked during the tests of Clause 19.

3 Definitions
Add the following new definition:
3.103
flammable refrigerant
refrigerant with a flammability classification of group 2 or 3 in accordance with ISO 5149
NOTE For refrigerant blends that have more than one flammability classification, the most unfavourable
classification is taken for the purposes of this definition.
4 General requirement
Addition:
NOTE 101 The use of flammable refrigerants involves additional hazards that are not associated with
appliances using non-flammable refrigerants.
This standard addresses the hazards due to ignition of flammable refrigerant by potential ignition sources
associated with the appliance.
The hazard due to ignition of flammable refrigerant by an external potential ignition source associated with the
environment in which the appliance is installed is compensated by the low probability of ignition.

5 General conditions for the tests
5.2 Addition:
At least one additional specially prepared sample is required for the tests of 22.108.
NOTE 101 Unless the motor-compressor conforms to IEC 60335-2-34, at least one additional specially prepared
sample may be required for the test of 19.1.
NOTE 102 At least one additional sample of the fan motor and its thermal motor protector may be required for the
