[中文适用范围]： 第 1 部分的本条款由以下内容取代。本国际标准涉及家用和类似用途的用于将水加热至沸腾温度以下的电热水器的安全，其额定电压单相器具不超过250V，其他器具不超过480V。注 101：带有裸露加热元件的即热式热水器属于本标准的范围。不适合正常家庭使用但可能对公众造成危险的电器，例如用于轻工业商店@和农场@的电器均属于本标准的范围。在可行的情况下，本标准涉及家庭内和周围所有人都会遇到的电器所带来的常见危险。然而@一般来说@它没有考虑到谁的人（包括儿童）？身体@感觉或心理能力；或者 ？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； - 儿童玩耍该设备。注 102 请注意以下事实： - 对于用于车辆、船舶或飞机上的设备，可能需要附加要求； - 在许多国家@国家卫生当局@负责劳工保护的国家当局和类似当局规定了额外要求； - 在许多国家/地区，对连接到总水管的设备的安装都有规定。注 103：本标准不适用于加热液体的器具（IEC 60335-2-15）； -储水式热水器（IEC 60335-2-21）； - 专门用于工业用途的设备； - 打算在特殊条件下使用的设备@，例如存在腐蚀性或爆炸性气氛（灰尘@蒸汽或气体）； -商业分配设备和自动售货机（IEC 60335-2-75）。 [外文原描述]： IEC 60335-2-35:2012 deals with the safety of electric instantaneous water heaters for household and similar purposes and intended for heating water below boiling temperature, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. Instantaneous water heaters incorporating bare heating elements are within the scope of this standard. 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 knowledge prevents them from using the appliance safely without supervision or instruction or children playing with the appliance. This fifth edition cancels and replaces the fourth edition published in 2002, including its Amendment 1 (2006) and its Amendment 2 (2009). The principal changes in this edition as compared with the fourth edition of IEC 60335-2-31 are as follows: - converted notes to normative text (7.12, 7.102, 8.1.5, 22.104, and 22.109.3); - deleted notes in 19.13, 22.109, and A.101; - added Annex R and 22.108 for appliances with programmable electronic circuits and added requirements for water heaters (22.50, 22.51). 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: Water heater, Instantaneous, open-outlet, bare-element. This publication is to be read in conjunction with IEC 60335-1:2010 .
