家用和类似用途电器.安全性.第2-41部分:泵的详细要求

[中文适用范围]： 本国际标准适用于液体温度不超过 90°C、用于家庭及类似用途、额定电压单相不超过 250V 或其他电器不超过 480V 的电动泵的安全。适用设备示例包括：水族箱泵、花园池塘泵、淋浴增压泵、污泥泵、潜水泵、桌式喷泉泵、立式湿井泵。本标准也适用于非正常家庭使用但可能对公众构成危险的设备，例如由非专业人士在商店、轻工业和农场使用的设备。本标准通常不考虑以下情况：身体、感官或精神能力有缺陷，或缺乏经验和知识而无法在无人监督或指导下安全使用设备的人员（包括儿童）；儿童将设备作为玩具玩耍。本标准不适用于：用于供暖和生活热水安装的固定循环泵（IEC 60335-2-51）；用于易燃液体的泵；专门用于工业目的的泵；用于特殊环境（如存在腐蚀性或爆炸性气氛，如粉尘、蒸汽或气体）的泵；带有电解型氯化器的泵。除非有特定引用，否则嵌入设备中的泵不在此标准范围内。 [外文原描述]： IEC 60335-2-41:2012 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. Examples of appliances within the scope of this standard are aquarium pumps, pumps for garden ponds, shower-boost pumps, sludge pumps, submersible pumps, table fountain pumps and vertical wet pit pumps. This fourth edition cancels and replaces the third edition published in 2002 including its Amendment 1 (2004) and its Amendment 2 (2009). It constitutes a technical revision. The principal changes in this edition as compared with the third edition of IEC 60335-2-41 are as follows: - added a normative reference to IEC 60364-7-702 and updated the title for IEC 60364-7-701, - clarified the normal operation for pumps in 3.1.9, - added requirements for deep well pumps in 3.105 and 25.8, - modified 15.102 to indicate that the tube connecting the inlet to the outlet may go via a tank containing a suitable volume of water so as to avoid overheating the pump, - deleted references in the bibliography and deleted or converted to normative the notes from 7.1, 22.101, and 22.106. The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 12 months or later than 36 months from the date of publication. Keywords: Pumps, submersible, sludge, shower-boost.
