Safety of household and similar electrical appliances - Part 121 : Particular requirements for professional ice-cream makers 1 Scope This clause of GB/T 4706.1-2024 is replaced by the following. This standard deals with the safety of appliances for making ice cream and artisan gelato. This standard applies to the appliances not intended for normal household use but which may nevertheless be a source of danger to the public, such as appliances intended to be used by laymen in shops, stores 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 may be remote. 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, an 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. Note 101: 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 the 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 with a refrigerating system operating with flammable refrigerant; – ice cream appliances for household use ( GB/T 4706.13); – 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). 2 Normative references This clause of GB/T 4706.1-2024 is applicable except as follows.

Appliances are operated the time necessary to reach steady state conditions. For appliances connected to a water supply, the water other than cooling water, is at a temperature of 15°C ± 2°C and at and the most unfavourable pressure specified in the instructions. The cooling water is at the temperature specified in 5.7. For appliances with a separate refrigerant unit, the refrigerant unit is connected to the cabinet in accordance with the manufacturer’s instructions. 3.1.9.102 normal operation for pasteurising ice cream making appliances pasteurising ice cream making appliances operated under the following conditions: Appliances are operated at ambient temperature as indicated in 5.7. The appliance is filled using the maximum quantity of the mixture of ingredients indicated in the instructions which gives the most unfavourable results, the mixture being at an initial temperature of 23 °C ± 2 °C. The appliance shall be operated for the time necessary for the mix to reach the maximum pasteurisation temperature and then, for the cooling process, for the number of cycles needed to reach steady state conditions. 3.1.9.103 normal operation for cream whipping appliances cream whipping appliances operated under the following conditions: Appliances are operated at an ambient temperature as indicated in 5.7. The appliance is filled with liquid cream being kept at preservation temperature of 4 °C ± 1 °C in the maximum quantity prescribed by the instructions and shall be operated the time necessary to reach steady state conditions. The appliance is operated in continuous or cyclic mode, following the instructions for user. 3.101 compression-type appliance appliance in which refrigeration is effected by the vaporisation at low pressure in a heat exchanger (evaporator) of a liquid refrigerant, the vapour thus formed being restored to the liquid state by mechanical compression at a higher pressure and subsequent cooling in another heat exchanger (condenser) 3.102 condenser heat exchanger in which, after compression, vaporised refrigerant is liquefied by rejecting heat to an external cooling medium 3.103 evaporator heat exchanger in which, after pressure reduction, the liquid refrigerant is vaporised by absorbing heat from the medium to be refrigerated 3.104 refrigerant unit factory assembled unit for performing part of the refrigeration cycle (compressing gas, condensation or gas cooling) comprising one or more refrigerant compressors with motors, condensers, liquid receivers, interconnecting pipe work and ancillary equipment all mounted on a common base 3.105 heating system heating element with associated components such as timers, switches, thermostats and other controls 3.106 ancillary heating element heating device which performs an auxiliary function, such as a defrost heater, door heater or anti-condensation heater 3.107 pasteurising cycle cycle during which the mixture is brought to the pasteurising temperature and then immediately cooled down to a preservation temperature ≤ 5 °C 3.108 skilled person person having the appropriate training and experience necessary to be aware of hazards to which they are exposed in performing a task and of measures to minimise the danger to themselves or other persons 3.109 free space any space with a volume exceeding 60 L where a child can be entrapped and which is accessible after opening any door, lid or drawer and removing any detachable internal parts, including shelves, containers or drawers which are only accessible after opening any door, lid or drawer In calculating the volume, a space with any single dimension not exceeding 150 mm or any two orthogonal dimensions each of which do not exceed 200 mm is ignored. 4 General requirement This clause of GB/T 4706.1-2024 is applicable. 5 General conditions for the tests This clause of GB/T 4706.1-2024 is applicable except as follows. 5.2 Addition: Note 101: Separate samples of the motor-compressor can be needed for the tests of 19.1. 5.3 Addition: The test of 15.101 is carried out immediately after the test of 15.2. 5.4 Replacement: For appliances intended to be connected to water supply, water is supplied at the appropriate rated pressure, according to the instructions.
