Safety of household and similar electrical appliances - Part 35: Particular requirements for commercial electric boiling pans
1 Scope
This clause of GB/T 4706.1-2024 is replaced by the following.
This standard deals with the safety of electrically operated commercial boiling pans not intended for household and similar use, their rated voltage being not more than 250 V for single-phase appliances connected between one phase and neutral, and 480 V for other appliances.
Note 101: These appliances are used for commercial processing of food, for example in kitchens of restaurants, canteens, hospitals and 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 are specified by the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities;
? in many countries additional requirements are specified for pressure appliances.
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);
? continuous process appliances for the continuous 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
The appliance is filled with water at 15 °C ± 5 °C to the indicated level.
Appliances with more than one programme are operated with the most severe programme. In addition, any control intended to be operated by the user is set at maximum until the water boils or the operating temperature is reached. The control is then adjusted to the lowest setting that maintains boiling or the operating temperature. Lids and covers are in position and closed.
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
boiling pan
an appliance in which liquids contained in a vessel are heated to boiling point as part of a cooking process. The pressure within the vessel can exceed atmospheric pressure. The vessel may be fixed or tilting
3.102
atmospheric boiling pan
a boiling pan in which the pressure within the vessel does not differ significantly from atmospheric pressure
3.103
jacketed boiling pan
an appliance having a double-walled vessel, the space between the inner and outer walls containing a heat transfer medium that is heated by heating elements
3.104
dual purpose boiling pan
an appliance incorporating two vessels, the inner one being removable. The appliance may be used with or without the removable vessel
3.105
unjacketed boiling pan
an appliance in which heating of the contents of the vessel is achieved by means other than via a heat transfer jacket
3.106
rated pressure
the maximum working pressure assigned by the manufacturer to the pressurized parts of the appliance
3.107
indicated level
a mark on the appliance to indicate the maximum liquid level for correct operation
3.108
installation wall
a special fixed construction containing supply facilities for appliances installed in conjunction with it
3.109
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.
3.110
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.
5.5 Addition:
Tests are carried out with the vessel in the position of normal use for cooking.
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.
5.103 Tests on dual purpose boiling pans are carried out with or without the inner vessel, whichever imposes the more severe condition, taking into account the manufacturer's instructions.
