IEC 60335-2-35:2012涉及家用和类似用途的电即热式热水器的安全性，用于加热低于沸点的水，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。包含裸露加热元件的即热式热水器在本标准的范围内。不用于正常家庭使用但可能对公众造成危险的电器，如用于商店、轻工业和农场的非专业人员使用的电器，属于本标准的范围。在可行的情况下，本标准涉及家庭内外所有人都会遇到的电器带来的常见危险。然而，一般来说，它没有考虑到那些身体、感官或精神能力或缺乏经验和知识使他们无法在没有s的情况下安全使用设备的人（包括儿童）监督或指导或儿童玩设备。这第五版取消并取代了2002年出版的第四版，包括其修正案1（2006年）和修正案2（2009年）。与IEC 60335-2-31第四版相比，该版本的主要变化如下: -将注释转换为规范性文本（7.12、7.102、8.1.5、22.104和22.109.3）； -删除19.13、22.109和A.101中的注释； -为带有可编程电子电路的电器增加了附件R和22.108，并增加了对热水器的要求（22.50、22.51）。请国家委员会注意，设备制造商和测试组织在新的、修订的或修订的IEC出版物出版后可能需要一个过渡期，以便根据新的要求制造产品，并为进行新的或修订的测试做好准备。委员会建议，该出版物的内容应在出版之日起12个月或36个月内通过，以便在全国范围内实施。 关键词:热水器，即热式，开式，裸露元件。 本出版物应与IEC 60335-1:20 10一起阅读。

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.
