家用和其他类似电器 - 安全 - 第2-118部分：商用冰淇淋机的特殊要求

[中文适用范围]： 本部分IEC 60335涉及专业用户专门操作的冰淇淋和手工冰淇淋制作设备的安全性。 适用于商业环境中使用的冰淇淋制作设备，如餐厅、酒店、超市、商店以及酒吧、面包房、冰淇淋店、机构餐饮等专业场所的制备区域。 考虑的电器是那些用于商业用途的电器，以及类似的不用于正常家庭使用但仍可能对公众造成危险的电器，如商店、工匠或农场中使用的电器，其额定电压单相不超过250V，其他电器不超过480V。 本标准涵盖的电器配备有制冷剂冷凝单元，通常是内置的，但对于某些电器可以是远程的。 本标准尽可能处理这些类型电器所呈现的常见危险，包括使用易燃制冷剂和使用R-744制冷剂的电器。 本标准不适用于制冷剂质量超过22.112规定限值的电器，也不适用于使用ISO 817中B类毒性制冷剂的电器。 本标准也不涵盖制冷设备的结构和操作特性，这些特性在ISO标准中有所规定。 本标准还适用于以下类型的电器： 在制备产品过程中，在冷却过程之前在电器内进行加热过程的冰淇淋和类似糕点产品的混合器； 用于在冷藏罐中储存打发奶油混合物并在输送过程中打发奶油的电器； 设计用于生产软冰淇淋并直接将其分配到容器中的冷冻机； 软冰淇淋机； 分批分配冷冻机。 本标准不适用于： 在任何制冷回路中易燃制冷剂充注量超过150g的分体系统； 家用冰淇淋电器（IEC 60335-2-24）； 专门用于工业用途的电器； 用于存在特殊条件（如腐蚀性或爆炸性环境）的场所的电器。 [外文原描述]： CORRECTED VERSION 2026-01 IEC 60335-2-118:2025 deals with the safety of appliances for making ice cream and artisan gelato exclusively operated by professional users. Ice cream makers intended for professional use are employed in commercial environments, such as restaurants, hotels, supermarkets, shops, as well as in preparation areas of bars, bakeries, ice cream shops, institutional catering, and other similar professional settings. Appliances taken into account are those intended for commercial use and similar appliances not intended for normal household use but which can nevertheless be a source of danger to the public, such as appliances intended to be used by laymen in shops, stores, by artisans or on farms, which rated voltage is not more than 250 V for single-phase appliances and 480 V for other appliances. Appliances covered by this standard are provided with a refrigerant condensing unit which is usually incorporated, but for some appliances can be remote. As far as is practicable, this standard deals with the common hazards presented by these types of appliances including those that use flammable refrigerants and appliances employing R-744 refrigerant. This standard is not applicable to appliances with a mass of flammable refrigerant exceeding the limits specified in 22.112 or to appliances with that use refrigerants with a toxicity classification of B according to ISO 817. It does not cover those features of construction and operation of refrigerating appliances that are dealt with in ISO standards. This standard also applies to following types of appliances: – mixers to make ice cream and similar pastry products in which, for the preparation of the product, heating process is made within the appliance before the cooling process; – appliances for storing whipping cream mix in a refrigerated tank and for whipping the cream for the delivery process; – freezers designed to produce soft ice cream and dispense it directly into containers; – machines for soft-serve ice cream; – batch dispensing freezers. Attention is drawn to the fact that: – countries can have additional requirements for appliances incorporating pressure vessels; – 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; – for appliances or parts of appliances intended to be used outdoors, additional requirements can be necessary. This standard does not apply to: – split systems having a refrigerant charge of flammable refrigerant exceeding 150 g in any refrigerating circuit; – ice cream appliances for household use (IEC 60335-2-24); – appliances intended 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). This second edition cancels and replaces the first 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) the text has been aligned with IEC 60335-1:2020; b) scope has been revised (Clause 1); c) requirements for appliances employing R-744 system have been added (7.1, 7.12.1, 22.7, 22.111); d) additional requirements for appliances employing flammable refrigerant have been added (7.1, 7.6, 7.12, 7.15, 21.105, 22.110, 22.112, 22.113, 22.114, 22.115, 22.116, 22.117, 22.118, 22.119, 22.120, 22.121, 22.122, 22.123, Annex CC); e) definition of hermetically sealed system has been revised (3.6.113); f) reference to flammable refrigerant has been deleted (22.7); g) new subclauses have been added (22.40, 22.49, 22.51); h) compatibility tests for winding insulation of motor-compressors used with different types of refrigerants and oils have been introduced (22.9); i) Annex AA has been modified to cover motors that are supplied at a voltage that is different from the rated voltage of the appliance; j) Annex BB has been updated to align with the latest edition of IEC 60079-15; k) text in 3.1.9.101, 3.1.9.102 and 3.1.9.103 has been cancelled and the text copied in 5.102; l) new informative tightness routine test has been added (Annex A). 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. The content of the corrigendum 1 (2026-01) has been included in this copy.
