This extended version of the official IEC Standard is available in English only and provides the user with a comprehensive content of the Standard. IEC 60335-2-118:2025 EXV includes the content of the references made to IEC 60335-1:2020. 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.
