GB/T 4706.61-2024 Safety of household and similar electrical appliances - Part 61 : Particular requirements for surface-cleaning appliances for household use employing liquids or steam
1 Scope
This clause of GB/T 4706.1-2024 is replaced by the following.
This standard specifies the safety of surface-cleaning appliances for household use employing liquids or steam.
This standard is applicable to surface-cleaning appliances for household use employing liquids or steam and wallpaper strippers rated voltage being not more than 250 V.
Note 1: Appliances may incorporate heating elements or means for pressurising the liquid container.
As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home.
However, in general, it does not take into account
– persons (including children) whose
? physical, sensory or mental capabilities; or
? lack of experience and knowledge
prevents them from using the appliance safely without supervision or instruction;
– children playing with the appliance.
Note 2: Attention is drawn to the fact that
– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary;
– in many countries additional requirements may be specified by the national health management authorities.
Note 3: This standard does not apply to
– floor treatment and wet scrubbing machines (GB/T 4706.57);
– cleaning appliances that are permanently fixed to a building;
– appliances covered by GB/T 4706.89, namely those having a
? pressure exceeding 2.5 MPa;
? pressurised volume over 5 L;
? product of pressure (in MPa) and container volume (in L) exceeding 5;
? liquid temperature exceeding 160 °C;
? rated power input exceeding 3500 W;
– cleaning appliances intended for commercial or industrial use;
– appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas);
– fabric steamers (GB/T 4706.84).

3 Terms and definitions
This clause of GB/T 4706.1-2024 is applicable except as follows.
3.1.9 Replacement:
normal operation
operation of the appliance under the most unfavourable conditions specified in the instructions
The cleaning head is pressed with a force of 30 N against a vertical pane of plain glass and moved up and down over a length of 1 m at a rate of 15 cycles per minute. A film of water is maintained on the pane of glass by continuously applying water having a temperature of 20° C ± 5 °C.
For steam cleaners and wallpaper strippers, a sheet of stainless steel is used instead of glass, without additional wetting. However, if the steam outlet is not intended to be pressed against the surface, the appliance is operated with the outlet in free air directed downwards at an angle of approximately 45°.
For steam cleaners intended to clean horizontal surfaces, the sheet of stainless steel is horizontal and the appliance is moved forward and backward over a length of 1 m at a rate of 15 cycles per minute instead of up and down. No additional force other than the weight of the appliance is applied.
3.101
pressurised appliance
appliance in which steam is produced in a boiler at a pressure exceeding 50 kPa and in which the pressure does not drop to atmospheric pressure when the steam is not supplied
Note: The boiler may be incorporated in the appliance or connected to the appliance by a hose.
