3 Definitions
This clause of Part I is applicable except as follows.
3.1.9 Replacement:
normal operation
operation of the appliance under the following conditions
The appliance is operated filled with textile material having a mass in the dry condition equal to the maximum load stated in the instructions.
The textile material consists of pre-washed double-hemmed cotton sheets having dimensions approximately 70 cm x 70 cm and a specific mass between 140 g/m2 and 175 g/m2 in the dry condition. The textile material is soaked with water having a temperature of 25 °C ± 5 °C and a mass equal to that of the textile material.
If the drying function can automatically follow the washing function in a washing machine, the appliance is not separately loaded. The appliance is operated with the maximum quantity of textile material stated in the instructions for the combined washing-drying cycle.
NOTE 101 cotton having a water content not exceeding 10 % is considered to be in the dry condition. Cotton conditioned for 24 h in still air, having a temperature of 20 °C ± 2 °C, a relative humidity between 60 % and 70 % and a pressure between 860 mbar and 1 060 mbar, will contain approximately 7 % water.
3.101
tumble dryer
appliance in which textile material is dried by tumbling in a rotating drum through which heated air is blown
3.102
condensation-type tumble dryer
tumble dryer in which the air used for the drying process is dehumidified by cooling
4 General requirement
This clause of Part 1 is applicable.
5 General conditions for the tests
This clause of Part 1 is applicable.
6 Classification
This clause of Part 1 is applicable except as follows.
6.2 Addition:
Appliances shall be at least IPX4.
7.12 Addition:
The instructions for use shall state
— the maximum mass of dry textile material in kilograms to be used in the appliance;
— that the tumble dryer is not to be used if industrial chemicals have been used for cleaning;
— that the lint trap has to be cleaned frequently, if applicable;
— that lint must not to be allowed to accumulate around the tumble dryer (not applicable for appliances intended to be vented to the exterior of the building);
— that adequate ventilation has to be provided to avoid the back flow of gases into the room from appliances burning other fuels, including open fires.
NOTE 101 This instruction is not required if the tumble dryer discharges the air into the room.
If symbols 5036 or 5041 of IEC 60417-1 are used, their meaning shall be explained.
7.12.1 Addition:
The installation instructions shall state
— for condensation-type tumble dryers intended to be connected to the water mains
• that the appliance is to be connected to the water mains using a new hose-set and old hose-sets should not be reused;
NOTE 101 This instruction is not required if the hose is permanently attached to the appliance.
• the maximum permissible inlet water pressure, in megapascals;
• the minimum permissible inlet water pressure, in megapascals, if this is necessary for correct operation of the appliance;
— for appliances with ventilation openings in the base, that a carpet must not obstruct the openings;
— that exhaust air must not be discharged into a flue which is used for exhausting fumes from appliances burning gas or other fuels.
NOTE 102 This instruction is not required if the tumble dryer discharges the air into the room.
If the installation instructions state that the tumble dryer can be placed on top of a washing machine, they shall state which washing machines are suitable. Instructions shall be given for the assembly of the tumble dryer and washing machine. The instructions shall state how to obtain any fixing attachments required, unless they are supplied with the appliance.
7.14 Addition:
The height of symbol 5036 of IEC 60417-1 shall be at least 5 mm and the height of symbol 5041 shall be at least 15 mm.
Compliance is checked by measurement.
7.101 The enclosure of magnetic valves, and similar components incorporated in external hoses for direct connection to the water mains, shall be marked with symbol 5036 of IEC 604 17-1 if their working voltage exceeds extra-low voltage.
NOTE This symbol is a warning sign and the rules of ISO 3864 apply.
Compliance is checked by inspection.
7.102 The rear surface, other than that of fixed appliances, shall be marked with symbol
5041 of IEC 60417-1 if its temperature rise exceeds the limits specified in 11.8 for accessible
front surfaces.
NOTE This symbol is a warning sign and the rules of ISO 3864 apply.
Compliance is checked by inspection.
