This clause of Part 1 is replaced by the following.

This part of IEC 60335 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).
