[中文适用范围]： 本部分 IEC 60335 涉及以下电器的安全性，其额定电压不超过单相电器 250 V，其他电器 480 V，以及电池供电的电器 24 V DC： - 家用和类似用途的制冷电器； - 带有电动机压缩机的制冰机和用于冷冻食品储存室的制冰机； - 用于露营、旅游大篷车和休闲船的制冷电器和制冰机。 这些电器可以由主电源、独立电池或两者供电。 本标准还涉及家用的冰淇淋制作机的安全性，其额定电压不超过单相电器 250 V，其他电器 480 V。 它还涉及使用易燃制冷剂的家用和类似用途的压缩式电器。 本标准不包括其他 IEC 标准中涉及的制冷电器的构造和操作特征。 不用于正常家用但仍可能对公众造成危险的制冷电器，如商店、办公室和其他工作环境中的员工厨房区域的制冷电器，农场房屋和酒店、汽车旅馆和其他住宅环境中的客户使用的制冷电器，以及餐饮和类似非零售应用中的制冷电器，也在本标准的范围内。 本标准尽可能处理所有人在家中和周围遇到的电器常见危险。然而，一般来说，它不考虑以下情况： - 身体、感官或精神能力不足或缺乏经验和知识的人（包括儿童）在没有监督或指导的情况下无法安全使用电器； - 儿童玩耍电器。 注1：请注意，对于用于车辆、船舶或飞机上的电器，可能需要额外的要求； - 在许多国家，国家卫生部门、劳动保护部门、国家供水部门和类似部门规定了额外的要求。 注2：本标准不适用于： - 用于户外的电器； - 专为工业用途设计的电器； - 用于特殊环境（如腐蚀性或爆炸性环境）的电器； - 包含用于制冷功能的电池的电器； - 由安装人员现场组装的电器； - 带有远程电动机压缩机的电器； - 电动机压缩机（IEC 60335-2-34）； - 商业分配设备和自动售货设备（IEC 60335-2-75）； - 用于食品（包括饮料）零售展示的商业冰箱和冰柜，带有内置或远程制冷单元或电动机压缩机的制冷电器和制冰机（IEC 60335-2-89）； - 商业冰淇淋制作机（IEC 60335-2-118）。 [外文原描述]： IEC 60335-2-24:2020 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 60335-2-24:2020 edition 8.0 and the previous edition IEC 60335-2-24:2010+AMD1:2012+AMD2:2017 CSV edition 7.2. Futhermore, comments from IEC TC 61 experts are provided to explain the reasons of the most relevant changes. IEC 60335-2-24:2020 deals with the safety of the following appliances, their rated voltage being not more than 250 V for single-phase appliances, 480 V for other appliances and 24 V DC for appliances when battery operated: – refrigerating appliances for household and similar use; – ice-makers incorporating a motor-compressor and ice-makers intended to be incorporated in frozen food storage compartments; – refrigerating appliances and ice-makers for use in camping, touring caravans and boats for leisure purposes. These appliances may be operated from the mains, from a separate battery or operated either from the mains or from a separate battery. This standard also deals with the safety of ice-cream appliances intended for household use, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. It also deals with compression-type appliances for household and similar use, which use flammable refrigerants. This standard does not cover features of the construction and operation of those refrigerating appliances which are dealt with in other IEC standards. Refrigerating appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as – refrigerating appliances used in staff kitchen areas in shops, offices and other working environments, – refrigerating appliances used in farm houses and by clients in hotels, motels and other residential type environments, – refrigerating appliances used in bed and breakfast type environments, and – refrigerating appliances used in catering and similar non-retail applications 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 aircraft, additional requirements can be necessary; – in many countries, additional requirements are specified by 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 intended to be used in the open air; – appliances designed exclusively for industrial purposes; – appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas); – appliances incorporating a battery intended as a power supply for the refrigerating function; – appliances assembled on site by the installer; – appliances with remote motor-compressors; – motor-compressors (IEC 60335-2-34); – commercial dispensing appliances and vending appliances (IEC 60335-2-75); – commercial refrigerating appliances and ice-makers with an incorporated or remote refrigerant unit or motor-compressor (IEC 60335-2-89); – professional ice-cream makers (IEC 60335-2-118). This eighth edition cancels and replaces the seventh edition published in 2010, Amendment 1:2012 and Amendment 2:2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: – aligns the text with IEC 60335-1, Ed 5.2; – some notes have been converted to normative text or deleted (4, 5.2, 5.7, 7.1, 7.6, 7.10, 7.12, 19.1, 19.101, 19.102, 20.101, 20.102, 20.103, 20.104, 21, 22.7, 22.33, 22.101, 22.102, 22.103, 22.107, 22.108, 22.109, 30.1); – normative references and associated text have been updated (2, 22.108, 22.109, Table 102, Annex CC); – definition of free space has been clarified (3.6.104); – measurement of the input current of refrigerating appliances using inverter driven motor-compressors is included (10.2); – compatibility tests for winding insulation of motor-compressors used with different types of refrigerants and oils have been introduced (22.9); – requirements for inadvertent contact points between uncoated aluminium pipes and copper pipes have been updated (22.111); – testing of accessible glass panels has been clarified (22.116); – in refrigerating appliances, requirements for material encasing and in contact with thermal insulation have been introduced and consequential text has been deleted (22.117, 30.2, 30.2.101, Annex EE); – requirements for motor running capacitors have been updated (24.5, 24.8); – the locked rotor test for fan motors has been clarified (Annex AA). This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments. It was established on the basis of the fifth edition (2010) of that standard. The contents of the corrigendum of August 2021 have been included in this copy.
