Introduction of GB/T 4706.41-2024

GB/T 4706.41-2024 Safety of household and similar electrical appliances - Part 41: Particular requirements for portable heating tools and similar appliances 1 Scope This clause of GB/T 4706.1-2024 is replaced by the following. This International Standard deals with the safety of portable electric heating tools and similar appliances, their rated voltage being not more than 250 V. 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, in light industry and on farms, are within the scope of this standard. Appliances that may also be used when mounted on a support are within the scope of this standard. Note 101: Examples of appliances that are within the scope of this standard are ——branding tools; ——burning-in pens; ——conduit-soldering tools; ——dehorning tools; ——desoldering irons; ——firelighters; ——glue guns; ——heat guns; ——household film-welding appliances; ——paint strippers; ——plastic-cutting tools; ——soldering guns; ——soldering irons; ——stripping pliers; ——thermoplastic conduit-welding tools. As far as is practicable, this standard deals with the common hazards presented by appliances which are encountered by all persons in and around the home. However, in general, it does not in general 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 may be necessary; ——in many countries additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour and similar authorities. Note 103: This standard does not apply to ——hand-held motor-operated electric tools (IEC 60745); ——transportable motor-operated electric tools (IEC 61029); ——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); ——tools using high-frequency heating other than induction soldering irons; ——arc-welding equipment. 2 Normative references This clause of GB/T 4706.1-2024 is applicable. 3 Definitions This clause of GB/T 4706.1-2024 is applicable except as follows. 3.1.9 Replacement: normal operation operation of appliances under the following conditions Appliances having a stand are operated on the stand, unless otherwise specified. Other appliances are operated in accordance with the instructions, unless otherwise specified. Soldering guns and plastic-cutting tools incorporating a biased-off switch are operated in cycles in accordance with the instructions but they are switched on for at least 12 s with rest periods not exceeding 48 s. For soldering guns, the on-period is such that the temperature at the tip reaches at least 300 °C at the end of the first on-period. Household film-welding appliances are operated in cycles in accordance with the instructions but they are switched on at least for the time necessary to weld together two sheets of plastic film with rest periods not exceeding 2 min. The plastic film is high pressure (low density) polyethylene, each sheet having a thickness of 50 µm. Heat guns are operated with the airflow horizontal. Firelighters are operated to ignite charcoal placed in a tray having a diameter of 600 mm and a side 50 mm high. The pile of charcoal is 500 mm in diameter and 1 00 mm high at its centre. Contact firelighters are positioned with the heating element horizontal and inserted in the centre of the charcoal. Hot-air firelighters are positioned with the airflow horizontal, or directed downwards up to 45° if allowed by the construction, whichever is more unfavourable. 3.101 biased-off switch switch that automatically returns to the off position when its actuating member is released 3.102 branding tool appliance for marking wood, leather and other materials by means of a heated metal stamp 3.103 burning-in pen appliance for scribing on wood, leather and other materials by means of a heated tip 3.104 conduit-soldering tool appliance used for joining metal piping by means of solder 3.105 dehorning tool appliance for burning out horn buds 3.106 desoldering iron appliance for melting and removing solder 3.107 firelighter appliance for igniting solid fuel such as charcoal or wood 3.108 contact firelighter firelighter incorporating a heating element that is in direct contact with the fuel 3.109 hot-air firelighter firelighter that incorporates a fan and a heating element and blows hot air at the fuel 3.110 heat gun appliance that produces a jet of hot air Note: Heat guns may be used for fusing materials or for softening paint or plastics. 3.111 household film-welding appliance appliance for household use only, used for welding or cutting thin thermoplastic sheets by means of electrically heated parts between which the material is clamped 3.112 paint stripper appliance for softening paint using hot air Note: Paint strippers may incorporate a scraper. 3.113 soldering gun appliance incorporating a transformer, the soldering tip being part of the secondary circuit 3.114 soldering iron appliance having a heated tip for soldering
