家用和类似用途电器的安全第2-24部分:制冷设备、冰淇淋设备和制冰机的特殊要求

[中文适用范围]： 本部分IEC 60335涉及以下家用电器的安全，其额定电压不超过单相电器250V，其他电器480V，电池供电电器24V DC： - 家用及类似用途的制冷电器 - 包含电动压缩机的制冰机及用于家用冷冻食品储存室的制冰机 - 类似家用的制冷电器和制冰机（如露营、休闲住宿车辆、休闲船只等） - 移动式制冷电器 这些电器可由电源、可分离电池或其他能源（气体、液体和固体燃料）操作。 本标准还涉及休闲船只和船舶上使用的制冷电器（适用规范性附录FF），以及使用易燃制冷剂的压缩型家用电器。 不包括：户外电器（移动式除外）、工业专用电器、特殊环境用电器（腐蚀性/爆炸性环境）、现场组装的电器、远程电动压缩机、商用自动售货设备等。 [外文原描述]： IEC 60335-2-24:2025 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 intended for household use; – refrigerating appliances and ice-makers for applications similar to household use such as for camping, in leisure accommodation vehicles, on boats for leisure purposes and on board ships; – mobile refrigerating appliances. These appliances can be operated from the mains, from a separable battery or operated either from the mains or from a separable battery or from other sources of energy (gas, liquid and solid fuel). This standard deals also with refrigerating appliances intended for the use on boats for leisure purposes and on board ships, for which the normative Annex FF is applicable. 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 can 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 whose physical, sensory or mental capabilities or lack of experience and knowledge prevents them from using the appliance safely without supervision or instruction. Attention is drawn to the fact that – for appliances intended to be used in vehicles, leisure accommodation vehicles, boats for leisure purposes, 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. – for appliances that are operated additional from other sources of energy (gas, liquid and solid fuel), additional requirements can be necessary. This standard does not apply to – appliances intended for outdoor use, except for mobile refrigerating appliances; – 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 ninth edition cancels and replaces the eighth edition published in 2020. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) aligns the text with IEC 60335 1:2020; b) new probe 19 has been introduced (8.1.1, 8.1.3, 20.2); c) new exception for components inside the thermal insulation has been introduced (22.117); d) new requirement for mobile refrigerating appliances, appliances to be used in leisure accommodation vehicles like motor caravans, boats for leisure purposes and appliances to be used on board ships has been introduced (Clause 1, 3.5.107, 3.5.108, 7.1, 7.6, 7.12, 7.14, 19.103, 21.101, 24.3, Annex FF); e) text in 3.1.9.101, 3.1.9.102, 3.1.9.103 and 3.1.9.104 has been cancelled and the text copied in 5.104; f) new requirement for the evaluation of non-dangerous moving parts has been introduced (20.2); g) new abnormal test has been introduced (19.106); h) reference to flammable refrigerant has been deleted (22.7); i) new subclauses have been added (22.40, 22.49, 22.51); j) requirement for the evaluation of motor-compressor has been updated (24.1); k) Annex DD has been cancelled and the text copied to Annex A; l) design pressure has been changed in maximum allowable pressure (3.8.101). 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.
