GB/T 4706.33-2024 Safety of household and similar electrical appliances - Part 33: Particular requirements for commercial electric deep fat fryers
1 Scope
This clause of Part 1 is replaced by the following.
This document deals with the safety of electrically operated commercial deep fat fryers and doughnut fryers including pressurized types with a pressure not exceeding 50 kPa and a pressure volume litres product of 200. These appliances are 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 the 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 relevant national regulatory 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);
——appliances for continuous mass production of food.

3 Terms and definitions
This clause of Part 1 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 oil or fat according to the manufacturer's instructions up to the minimum indicated level.
The thermal control is set at the maximum setting. Lids, if provided, are left in the open position or removed unless the manufacturer's instructions indicate that the appliance is designed for operation with the lid 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
deep fat fryer
appliance provided with one or more containers in which the food to be cooked is immersed in the frying medium
Note 1: The container(s) may be fixed, removable, lifting, tilting, etc.
Note 2: The pressure within the container can exceed atmospheric pressure.
3.102
indicated level
mark on the appliance to indicate either the minimum or the maximum liquid level for correct operation
3.103
installation wall
special fixed construction containing supply facilities for appliances installed in conjunction with it
3.104
rated pressure
the maximum working pressure assigned by the manufacturer to the pressurized part of the appliance
3.105
doughnut fryer
appliance with large surface area and flat container in which the bakery products e. g. donuts are prepared in fat or oil by floating
The doughnut fryer is generally not equipped with a cold area. The appliance can be delivered with a removable bakery product basket, a lifting or turning device.
3.106
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
3.107
adjacent surface
surface adjacent to a functional surface and which can become hot through conduction
4 General requirement
