GB/T 4706.38-2024 Safety of household and similar electrical appliances - Part 38: Particular requirements for commercial electric kitchen machines
1 Scope
This clause of GB/T 4706.1-2024 is replaced by the following.
This document deals with the safety of electrically operated commercial kitchen machines 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.
Note 102: Examples of kitchen machines are
——mixers;
——liquid or food blenders;
——kneaders;
——beaters;
——shredders;
——graters;
——mincers;
——slicers;
——peelers;
——tin openers;
——coffee grinders;
——machines used for washing and/or drying food;
——portioning machines;
——pastry rollers;
——noodle strip cutters;
——food processors;
——beam mixers.
This standard also applies to appliances which, in order to facilitate transport, are supplied in several parts (sub-assemblies) which, when assembled at the place of installation, form a constructional unit without the use of any additional parts.
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 103: 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.
Note 104: 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;
——independent conveying equipment, such as food distribution belts.

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 operated without load. The appliance is then loaded in appropriate steps, the supply voltage being maintained at its original value. For each step, steady conditions have to be established before increasing the load. This operation is repeated until just before an overload release operates, or until the steady condition with the highest temperature has been attained.
Note 101: The load may be achieved by using an electrical or mechanical brake.
Where it is not possible or is impractical to apply effectively an electrical or mechanical brake, the load is 115 % of the input measured when the appliance is operated without load at rated voltage and normal operating temperature, and with controls intended to be adjusted by the
user set at maximum.
Note 102: Examples of such appliances are
——liquid blenders;
——slicers;
——peelers;
——coffee grinders;
——machines used for washing and/or drying food;
——portioning machines.
3.101
indicated level
mark on the appliance to indicate the maximum liquid level for correct operation
3.102
installation wall
special fixed construction containing supply facilities for appliances installed in conjunction with it
3.103
guard plate
plate similar to a slice thickness plate, fitted to machines with automatic product feeding
3.104
product holder
support for the product to be sliced. The product holder can be equipped with a pusher or a feed carriage and/or a clamping device
3.105
sliding feed table
device that supports the product holder and allows it to move forwards and backwards
3.106
feed carriage
device on which the product is placed and that slides on top of the product holder in order to move the product towards the blade
3.107
pusher
device used to move the product along the product holder against the thickness plate
3.108
last slice device
plate with which the last portion of the product is fed to the cutting blade
Note: The plate can be fitted on the pusher, clamping device or feed carriage.
