前言这是CAN/CSA-E60335-2-41《家用和类似用途电器-安全-第2-41部分:泵的特殊要求》的第三版，采用了相同名称的IEC（国际电工委员会）标准60335-2-41（第3:2002版与修订件1:2004和修订件2:2009合并）。它取代了2001年出版的前一版CAN/CSA-E60335-2-41《家用和类似用途电器的安全——第2部分:温度不超过35℃的液体泵的特殊要求》？C（采用IEC 335-2-41:1996）。本标准拟与CAN/CSA-C22结合使用。2第60335-1-11号，家用和类似用途电器的安全- 第1部分:一般要求（采用IEC 60335-1:2001+A1:2004+A2:2006，带有加拿大偏差）。范围第1部分的本条款替换为以下内容。本国际标准涉及温度不超过90°C的液体电动泵的安全性？C、 用于家用和类似用途，单相电器的额定电压不超过250 V，其他电器的额定电压不超过480 V。注101本标准范围内的器具示例包括:水族箱泵花园池塘用水泵淋浴增压泵；-污泥泵潜水泵；-桌上喷泉泵；-立式湿坑泵。不适用于正常家用，但可能对公众造成危险的电器，如商店、轻工业和农场外行使用的电器，均在本标准的范围内。 在切实可行的范围内，本标准涉及所有人在家中和家中周围遇到的电器的常见危险。然而，一般来说，它不考虑——身体、感官或心理能力强的人（包括儿童）；或*缺乏经验和知识，使他们无法在没有监督或指导的情况下安全使用设备；-玩电器的孩子们。注102:需要注意的是，对于拟用于车辆、船舶或飞机上的设备，可能需要额外的要求；-在许多国家，国家卫生当局、负责保护劳工的国家当局和类似当局规定了额外的要求。 注103:本标准不适用于供暖和厂用水装置用固定循环泵（IEC 60335-2-51）；-易燃液体泵；-专用于工业用途的泵；-拟用于特殊条件下使用的泵，如存在腐蚀性或爆炸性环境（灰尘、蒸汽或气体）；-装有电解式氯化器的泵。注104:本标准不包括电器中的泵，除非有具体参考。

PrefaceThis is the third edition of CAN/CSA-E60335-2-41, Household and similar electrical appliances - Safety - Part 2-41: Particular requirements for pumps, which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 60335-2-41 (edition 3:2002 consolidated with Amendment 1:2004 and Amendment 2:2009). It supersedes the previous edition published in 2001 as CAN/CSA-E60335-2-41, Safety of household and similar electrical appliances - Part 2: Particular requirements for pumps for liquids having a temperature not exceeding 35?C (adopted IEC 335-2-41:1996).This Standard is intended to be used in conjunction with CAN/CSA-C22.2 No. 60335-1-11, Safety of Household and Similar Appliances - Part 1: General Requirements (adopted IEC 60335-1:2001+A1:2004+ A2:2006, with Canadian deviations).ScopeThis clause of Part 1 is replaced by the following. This International Standard 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.NOTE 101 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;- vertical wet pit pumps.Appliances not intended for normal household use, but that 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.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 knowledgeprevents 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- 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.NOTE 104 Pumps incorporated in appliances are not covered by this standard unless a specific reference is made.
