[中文适用范围]： IEC 60335-2-66:2025 RLV 包含官方 IEC 国际标准及其红线版本。红线版本仅提供英文版，可让您快速轻松地比较官方 IEC 标准与其先前版本之间的所有变化。IEC 60335-2-66:2025 涉及家用和类似用途的电水床加热器及其相关控制单元的安全，其额定电压不超过 250 V，包括直流 (DC) 供电电器。非用于正常家庭用途但可能对公众造成危险的电器，例如供酒店使用的电器，属于本标准的范围。在切实可行的范围内，本标准处理家庭内部和周围所有人可能遇到的电器所造成的常见危险。但是，一般而言，它不考虑 - 身体、感官或精神能力有障碍的人（包括儿童）；或者缺乏经验和知识导致他们在没有监督或指导的情况下无法安全使用器具； – 儿童玩耍器具。 请注意： – 对于旨在用于车辆、船舶或飞机上的器具，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、国家供水当局和类似当局规定了附加要求。 本标准不适用于以下器具 – 用于医疗目的（IEC 60601 系列）； – 旨在在使用过程中浸入水中。 第三版取消并取代 2002 年发布的第二版、修正案 1：2008 和修正案 2：2011。 此版本构成技术修订。 此版本与上一版相比包括以下重大技术变化： a) 与 IEC 60335-1:2020 一致； b) 将一些注释转换为规范性文本（条款 1、19.4、22.101）； c) 澄清远程操作的要求（22.40、22.49、22.51）。本第 2 部分应与 IEC 60335-1 的最新版本及其修订版结合使用，除非该版本排除该要求；在这种情况下，将使用不排除该要求的最新版本。它是在该标准第六版（2020 年）的基础上制定的。 [外文原描述]： IEC 60335-2-66:2025 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60335-2-66:2025 deals with the safety of electric water-bed heaters and their associated control units, for household and similar purposes, their rated voltage being not more than 250 V, including direct current (DC) supplied appliances. 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 in hotels, 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; – 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 in aircraft, additional requirements can be necessary; – in many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities. This standard does not apply to appliances – for medical purposes (IEC 60601 series); – intended for immersion in water during use. This third edition cancels and replaces the second edition published in 2002, Amendment 1: 2008 and Amendment 2:2011. 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) conversion of some notes to normative text (Clause 1, 19.4, 22.101); c) clarification of requirements for remote operation (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.
