家用和类似用途电器.安全.第2-41部分:泵的特殊要求

[中文适用范围]： 本部分 IEC 60335 涉及液体温度不超过 90°C 的家用和类似用途电动泵的安全，其额定电压不超过单相器具 250 V 和其他器具 480 V，包括直流供电器具和电池供电器具。 本标准范围内的器具示例包括： - 水族箱泵 - 花园池塘泵 - 淋浴增压泵 - 污泥泵 - 潜水泵 - 桌面喷泉泵 - 垂直湿井泵 不用于正常家用的器具，但仍可能对公众造成危险的器具（如供外行人在商店、轻工业和农场使用的器具）也在本标准范围内。 本标准尽可能处理所有人在家中及周围遇到的由器具引起的常见危险。但通常不考虑以下情况： - 因身体、感官或精神能力不足，或缺乏经验和知识而无法在没有监督或指导的情况下安全使用器具的人员（包括儿童） - 儿童玩耍器具的情况 注意： - 对于车辆、船舶或飞机上使用的器具，可能需要附加要求 - 许多国家的国家卫生当局、劳动保护当局等机构会规定附加要求 本标准不适用于： - 供暖和服务水装置的固定循环泵（IEC 60335-2-51） - 易燃液体泵 - 专用于工业目的的泵 - 在特殊条件下（如存在腐蚀性或爆炸性环境）使用的泵 - 包含电解型氯化器的泵 除非另有说明，本标准不涵盖器具中的内置泵。 [外文原描述]： IEC 60335-2-41:2024 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 60335-2-41:2024 edition 5.0 and the previous IEC 60335-2-41:2012 edition 4.0. Furthermore, comments from IEC TC 61 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content. IEC 60335-2-41:2024 deals with the safety of electric pumps for liquids having a temperature not exceeding 90 °C, intended for household and similar purposes, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances including direct current (DC) supplied appliances and battery-operated appliances. Examples of appliances within the scope of this standard are - aquarium pumps; - garden pond pumps; - shower-boost pumps; - sludge pumps; - submersible pumps; - table fountain pumps; - vertical wet pit pumps. Appliances not intended for normal household use, but that nevertheless can 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. As far as is practicable, this standard deals with the common hazards presented by ap-pliances that are encountered by all persons in and around the home. However, in gen-eral, 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. 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 authori-ties, the national authorities responsible for the protection of labour and similar au-thorities. This standard does not apply to - stationary circulation pumps for heating and service water installations (IEC 60335-2-51); - pumps for flammable liquids; - pumps intended exclusively for industrial purposes; - pumps intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas); - pumps incorporating chlorinators of the electrolytic type. Pumps incorporated in appliances are not covered by this standard unless a specific ref-erence is made. This fifth edition cancels and replaces the fourth edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) alignment with IEC 60335-1:2020; b) modification or conversion of some notes to normative text (Clause 1, 7.12.1, 25.7); c) introduction of IEC 60417 symbol for maximum operating depth and indoor use only (7.1, 7.6, 7.12.1); d) clarification of requirements for aquarium pumps and garden pond pumps; e) addition of legibility requirements for markings exposed to solar radiation (7.14); f) clarification of pumps subjected to test probe 18 (8.1.1, 20.2); g) introduction of accessible surface temperature limits (Clause 11); h) addition of requirements for IEC 61984 connectors for pumps intended for permanent connection to fixed wiring (22.107, 24.1.5, 24.1.101, 25.3). i) clarifications on remote operation for pumps in scope of this standard (22.40, 22.49, 22,51). This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments unless that edition precludes it; in that case, the latest edition that does not preclude it is used. It was established on the basis of the sixth edition (2020) of that standard.
