GB/T 4706.7-2024 Safety of household and similar electrical appliances - Part 7: Particular requirements for vacuum cleaners and water-suction cleaning appliances 1 Scope This clause of GB/T 4706.1-2024 is replaced by the following. This document deals with the safety of electric vacuum cleaners and water-suction cleaning appliances for household and similar purposes, including vacuum cleaners for animal grooming, their rated voltage being not more than 250 V. It also applies to centrally-sited vacuum cleaners and automatic battery-operated cleaners. This document also applies to motorized cleaning heads and current-carrying hoses associated with a particular vacuum cleaner. Battery-operated appliances and other DC supplied appliances are within the scope of this document. Dual supply appliances, either mains-supplied or battery-operated, are regarded as battery-operated appliances when operated in the battery mode. Appliances not intended for normal household use, but which nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops and other premises for normal housekeeping purposes, are within the scope of this standard. Note 101: Examples of such appliances are appliances intended to be used for normal housekeeping purposes in hotels, offices, schools, hospitals and similar premises. 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 102: Attention is drawn to the fact that: ——for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary; ——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 and similar authorities. Note 103: This standard does not apply to: ——appliances intended exclusively for industrial purposes; ——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); ——wet and dry vacuum cleaners, including power brush, for commercial use (GB/T 4706.93) 2 Normative references This clause of GB/T 4706.1-2024 is applicable except as follows: Addition: GB/T 31523.1-2015 Safety information identification systems - Part 1: Signs (ISO 7010:2011, MOD) Note: There is no technical difference between the content referenced in GB/T 31523.1-2015 and the content referenced in ISO 7010:2011.

The appliance is supplied at rated voltage and operated continuously with the air inlet adjusted to give a power input Pm after 20 s. Three minutes later, a final adjustment of the air inlet is made, if necessary. Pm is calculated from the formula where Pf is the power input in watts, after 3 min of operation with the air inlet unobstructed. Any device that ensures a flow of air to cool the motor in the event of a blockage of the main air inlet is allowed to operate: Pi is the power input in watts, after a further 20 s of operation with the air inlet blocked. Any device that is adjustable without the aid of a tool, and which ensures a flow of air to cool the motor in the event of a blockage of a main air inlet, is rendered inoperative. If Pi; has a rapid non-linear decrease or cannot be measured due to the appliance suction motor stopping before 20 s, the air inlet is gradually blocked to the extent that the motor stops after s. In this case, Pi is the maximum value of power input in the last two seconds before the motor shuts off. If the appliance is marked with a rated voltage range, it is supplied at the mean value of the range if the difference between the limits of the range does not exceed 10 % of the mean value. If the difference exceeds 10 %, the supply voltage is the upper value of the range. The measurements are made with the appliance fitted with a clean dust bag and filter, any water collection container being empty. If the appliance is intended to be used only with a hose, detachable nozzles and tubes are removed and the hose is laid out straight. If the appliance is provided with a hose as an accessory, it is operated without the hose. Rotating brushes and similar devices are in operation but not in contact with any surface Motorized cleaning heads are connected by means of the hose or tube and are in operation but not in contact with any surface. Appliance outlets for other accessories are loaded with a resistive load in accordance with the marking. Automatic battery-operated cleaners are operated with a clean dust bag or filter on the carpet meeting the construction specifications given in GB/T 38048.1-2020. A frame of 1.5 m by 1.5 m is used on the carpet to limit the area of action. The air inlet is unobstructed 3.5 Definitions relating to types of appliances 3.5.101 ash vacuum cleaner vacuum cleaner intended to vacuum cold ash from fireplaces, chimneys, ovens, ash-trays and similar places of ash accumulation 3.5.102 automatic battery-operated cleaner vacuum cleaner that operates without human control only within a defined perimeter, within a pre-programmed area or in an area self-controlled by the appliance Note 1: The cleaner consists of the mobile part and may have a docking station. 3.5.103 centrally-sited vacuum cleaner vacuum cleaner that is connected to a ducting system installed in the building Note 1: During use, the nozzle and its associated hose are connected to one of the suction inlets of the ducting system. 3.5.104 water-suction cleaning appliance appliance for aspirating an aqueous solution that may contain foaming detergent 3.6 Definitions relating to parts of an appliance 3.6.101 docking station unit that may provide ——manual or automatic battery charging facilities ——dust removal, ——data processing facility, and ——suction for the mobile part Note 1: A docking station is also known as a base unit. 3.6.102 motorized cleaning head accessory containing a motor that is supplied from the vacuum cleaner and which is attached to the end of a hose or tube 3.8 Definitions relating to miscellaneous matters 3.8.101 booster setting position of a control resulting in a temporary higher power input that is automatically reduced to the power input value when the setting is not used 4 General requirement This clause of GB/T 4706.1-2024 is applicable.
