GB/T 4706.93-2024 Safety of household and similar electrical appliances - Part 93: Particular requirements for wet and dry vacuum cleaners, including power brush, for commercial use 1 Scope This clause of 4706.1-2024 is replaced by the following. This document specifies the safety of commercial vacuum cleaners. This document deals with the safety of electrical motor-operated vacuum cleaners, including back-pack vacuum cleaners , and dust extractors , for wet suction, dry suction, or wet and dry suction, intended for commercial indoor or outdoor use with or without attachments. These machines may be provided with a blowing or inflating function . It also deals with the safety of centrally-sited vacuum cleaners , excluding the installation of the system. Note 101: Attention is drawn to the fact that additional requirements on the safe installation of centrally-sited vacuum cleaners are not addressed by this document but need to be taken into account. Note 102: This document applies to machines for commercial use. The following list, although not comprehensive, gives an indication of locations that are included in the scope: ——public use areas such as hotels, schools, hospitals; ——industrial locations, for example factories and manufacturing shops; ——retail outlets, for example shops and supermarkets; ——business premises, for example offices and banks; ——all uses other than normal housekeeping purposes. These machines are not equipped with a traction drive. The following power systems are covered: ——mains powered motors up to a rated voltage of 250 V for single-phase appliances and 480 V for other appliances, ——battery-operated motors. This document also applies to machines handling hazardous dust, such as asbestos, and combustible dust in other than an explosive dust atmosphere . Note 103: Additional requirements for machines handling hazardous dust are given in normative Annex AA. Note 104: Machines for the same intended function but equipped with a traction drive are covered. This document does not apply to ——vacuum cleaners and water-suction cleaning appliances for household use (IEC 60335-2-2); ——floor treatment machines for commercial use (IEC 60335-2-67, IEC 60335-2-72); ——spray extraction machines for commercial use (IEC 60335-2-68); ——hand-held mains-operated electrical garden blowers, vacuums and blower vacuums (IEC 60335-2-100); ——hand-held and transportable motor-operated electric tools (IEC 60745 series, IEC 61029 series, IEC 62841 series); ——appliances for medical purposes (IEC 60601-1); ——machines designed for use in corrosive environments; ——machines designed for picking up liquids with a flash point below 55 °C; ——machines designed for use in explosive environments (dust, vapour or gas), except those designed for use in zone 22; Note 105: The flash point temperature limits may vary in different countries (or regions). National (or regional) regulations need to be taken into account. Note 106: Appendix CC provides additional requirements for vacuum cleaners that collect combustible dust in Zone 22. Note 107: Relevant national regulatory authorities may impose additional requirements on equipment regulations. 2 Normative references This clause of 4706.1-2024 is applicable except as follows. Addition: ISO 2602 Statistical interpretation of test results - Estimation of the mean - Confidence interval ISO 6344-2 Coated abrasives - Grain size analysis - Part 2: Determination of grain size distribution of macrogrits P12 to P220 ISO 7731 Ergonomics - Danger signals for public and work areas - Auditory danger signals 3 Terms and definitions This clause of 4706.1-2024 is applicable except as follows. 3.1.9 Addition: normal operation conditions under which the machine is operated in normal use, obtained at the following power input P m of the vacuum motor: The measurements are made with the machine fitted with a clean dust bag and filter and with the water container, if any, empty. If the machine is intended for use only with a hose, detachable nozzles are removed and the hose is laid out straight. If the machine is provided with a hose as an optional accessory, it is operated without the hose. Electrically driven devices, if any, are in operation but are not in contact with the floor or any other surface or with the means used to seal the air inlet. 3.101 water-suction cleaning machine machine for sucking up a water-based cleaning solution 3.102 back-pack vacuum cleaner vacuum cleaner designed to have the power source and collector carried on the operator ’s back by means of a supporting device 3.103 motorized cleaning head hand-held or hand-guided cleaning device connected to the machine, with an integrated electrical motor Note: The permanently attached main cleaning head is not regarded as a motorized cleaning head. 3.104 hazardous dust non-radioactive dust which is hazardous to health if inhaled, ingested or in contact with the skin Note 1: IEC Directive 79/831/EEC amending 67/548/EEC lists dusts for which the general indication of nature of risk is specified as very toxic, harmful, corrosive or irritant; some dusts can be subject to an exposure limit in the country of use; micro-organisms can be considered as dusts creating a hazard to the health of a person. Note 2: Requirements for machines intended to pick up hazardous dust are specified in normative Annex AA.
