1 Scope
This clause of GB/T 4706.1-2024 is replaced by the following.
This document specifies the safety requirements for household and similar refrigerating appliances, ice cream appliances, and ice-makers.
This document 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;
——refrigerating appliances and ice-makers for use in camping, touring caravans and boats for leisure purposes.
These appliances may be operated from the mains, from a separate battery or operated either from the mains or from a separate battery.
This document 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 document 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 may 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 document.
As far as is practicable, this document 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 (including children) whose
• physical, sensory or mental capabilities or
• lack of experience and knowledge
prevents them from using the appliance safely without supervision or instruction;
——children playing with the appliance.
Note 1: 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 national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities.
This document does not apply to
——appliances intended to be used in the open air;
——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).

3 Terms and definitions
This clause of GB/T 4706.1-2024 is applicable except as follows.
3.1 Definitions relating to physical characteristics
3.1.9 replacement:
normal operation
operation of the appliance under the following conditions from 3.1.9.101 to 3.1.9.104.
3.1.9.101
normal operation of a refrigerating appliance
operation at an ambient temperature in accordance with 5.7, empty, with the doors and lids closed. User-adjustable temperature control devices which control the operation of the motor-compressor in compression-type appliances are short-circuited or otherwise rendered inoperative
3..9.102
normal operation of an ice-maker
operation at an ambient temperature in accordance with 5.7, with the supply water at a
temperature of 15 °C ± 2 °C
3.1.9.103
normal operation of an incorporated ice-maker
operation at the normal temperature of the frozen food storage compartment, with the supply water at a temperature of 15 °C ± 2 °C
3.1.9.104
normal operation of an ice-cream appliance
operation of the appliance using the maximum quantity of the mixture of ingredients indicated in the instructions; the mixture used being that which gives the most unfavourable results, the mixture being at an initial temperature of 23 °C ± 2 °C
3.5 Definitions relating to types of appliances
3.5.101
refrigerating appliance
enclosed thermally insulated appliance of suitable volume for household use, cooled by an incorporated device and having one or more compartments intended for the preservation of foodstuffs including cooling of beverages
3.5.102
compression-type appliance
appliance in which refrigeration is effected by the vaporization at low pressure in a heat exchanger (evaporator) of a liquid refrigerant, the vapour thus formed being restored to the original state by mechanical compression at a higher pressure and subsequent cooling in another heat exchanger (condenser)
3.5.103
ice-maker
appliance in which ice is made by freezing water by a device consuming electrical energy and having a compartment for storing the ice
3.5.104
incorporated ice-maker
ice-maker specially designed to be incorporated into a frozen food storage compartment and without independent means for freezing water
3.5.105
absorption-type appliance
appliance in which refrigeration is effected by the evaporation in a heat exchanger (evaporator) of a liquid refrigerant, in the liquid state, the resulting vapour being then absorbed by an absorbent medium from which it is subsequently expelled at a higher partial vapour pressure by heating and liquefied by cooling in another heat exchanger (condenser)
3.5.106
ice-cream appliance
compression-type appliance which is used to make ice-cream
3.6 Definitions relating to parts of an appliance
3.6.101
heating system
heating element with associated components such as timers, switches, thermostats and
other controls
3.6.102
condenser
heat exchanger in which, after compression, vaporized refrigerant is liquefied by losing heat to an external cooling medium
3.6.103
evaporator
heat exchanger in which, after pressure reduction, the liquid refrigerant is vaporized by
absorbing heat from the medium to be refrigerated
3.6.104
free space
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 part, including shelves, containers or removable drawers which are themselves only accessible after opening any door or lid
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.
Note: Evaluation of the ignored volume can be checked by applying a 150 mm ± 0.5 mm diameter sphere or a square with 200 ± 0.5 mm side without appreciable force. The volume can be ignored if the sphere or square cannot fit inside.
3.6.105
transcritical refrigeration system
refrigeration system where the pressure in the high pressure side is above the pressure where the vapour and liquid states of the refrigerant can coexist in thermodynamic equilibrium
3.6.106
gas cooler
heat exchanger in which, after compression, the refrigerant is cooled down, by transferring heat to an external cooling medium, without changing state
Note: A gas cooler is normally used in transcritical refrigeration systems.
3.7 Definitions relating to safety components
3.7.101
bursting disc
disc or foil which bursts at a predetermined pressure to reduce a pressure in a refrigeration system
