GB/T 4706.62-2024 Safety of household and similar electrical appliances - Part 62 : Particular requirements for commercial electric bains-marie
1 Scope
This clause of GB/T 4706.1-2024 is replaced by the following.
This standard specifies the safety requirements for electric bains-marie not intended for household use.
This standard is applicable to single-phase appliances with rated voltage being not more than 250 V and other appliances not more than 480 V.
Note 101: These appliances are used for the commercial processing of food, for example in kitchens of restaurants, canteens, hospitals and similar in commercial enterprises such as bakeries, butcheries, etc.
The electrical part of appliances making use of other forms of energy is also within the scope of this standard.
As far as is practicable, this standard deals with the common hazards presented by these types of appliances.
Note 102: Attention is drawn to the fact that
− for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary;
− in many countries additional requirements may be specified by the national management authorities;
− for appliances intended to be used outdoors, additional requirements may be necessary.
Note 103: This standard does not apply to
− 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 for continuous process appliances for the mass production of food.

3 Terms and definitions
This clause of GB/T 4706.1-2024 is applicable except as follows.
3.1.4 Addition:
Note 101: The rated power input is the sum of the power inputs of all the individual elements in the appliance that can be on at one time; where there are several such combinations possible, that giving the highest power input is used in determining the rated power input.
3.1.9 Replacement:
normal operation
operation of the appliance under the following conditions
Open-well and wet-heat-type bains-marie are filled with water to the indicated level and topped up during the test in accordance with the manufacturer's instructions. The appliance is operated with any control intended to be operated by the user set at maximum. If the water boils, the control is then adjusted to the lowest setting that maintains simmering. No covers or containers are fitted.
Dry-heat-type bains-marie are operated with any controls set at the maximum. Empty food containers are placed in the well but with the container covers removed.
Combined-type appliances are operated under the most unfavourable conditions.
Motors incorporated in the appliance are operated in the intended manner under the most severe conditions that can be expected in normal use taking into account the manufacturer's instructions.
3.101
bain-marie
an appliance with a well that is used for the storage of hot food in containers prior to serving. The containers are indirectly heated by hot air, steam or water in the well
3.102
open-well-type bain-marie
an appliance where the food containers rest in water in a heated well
3.103
wet-heat-type bain-marie
an appliance where the fitted food containers are heated by steam generated within the appliance. The pressure in the well or steam generator does not differ significantly from atmospheric pressure
3.104
dry-heat-type bain-marie
an appliance where the fitted food containers are heated by warm air generated within the appliance
3.105
indicated level
a mark on the appliance to indicate the maximum liquid level for correct operation
3.106
installation wall
a special fixed construction containing supply facilities for appliances installed in conjunction with it
3.107
functional surface
surface that is intentionally heated by an internal heat source and has to be hot to carry out the function for which the appliance is intended
Note: An example is the heated sheath of a tubular heating element.
3.108
adjacent surface
surface adjacent to a functional surface and which can become hot through conduction
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.
5.10 Addition:
Appliances intended for installation in a bank of other appliances and appliances intended to be fixed to an installation wall are enclosed to obtain protection against electric shock and harmful ingress of water equivalent to that obtained when installed in accordance with the instructions provided with the appliance.
Note 101: Appropriate enclosures or additional appliances may be needed for test purposes.
5.101 Appliances are tested as heating appliances, even if they incorporate a motor.
5.102 Appliances, when assembled in combination with, or incorporating, other appliances, are tested in accordance with the requirements of this standard. The other appliances are operated simultaneously in accordance with the requirements of the relevant standards.
