GB/T 4706.63-2024 Safety of household and similar electrical appliances - Part 63 : Particular requirements for commercial electric rinsing sinks
1 Scope
This clause of GB/T 4706.1-2024 is replaced by the following.
This standard specifies the safety requirements for commercial electric rinsing sinks.
This standard is applicable to single-phase appliances connected between one phase and neutral with rated voltage being not more than 250 V, and other appliances not more than 480 V.
Note 101: These appliances are used for example in kitchens of restaurants, canteens, hospitals and 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 can be necessary;
– for appliances intended to be used in tropical countries, special requirements can 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 103: This standard does not apply to
– appliances designed primarily for sterilizing to clinical standards;
– dishwashers (IEC 60335-2-58);
– 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).

3 Terms and definitions
This clause of GB/T 4706.1-2024 is applicable except as follows.
3.1 Definitions relating to physical characteristics
3.1.4 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:
Appliances are operated in accordance with the instructions, with all the controls intended to be operated by the user adjusted to their maximum setting. Lids and covers, if any, are placed in their intended position.
Appliances intended to be filled by hand or by a manually operated tap are filled to the indicated level.
Where several levels are marked, that giving the most unfavourable conditions is used.
Appliances intended to be filled automatically are connected to a water supply having the pressure designated by the manufacturer.
Where the manufacturer specifies a range of pressures, the pressure is adjusted to that giving the most unfavourable conditions.
The temperature of the water supplied is 15 °C ± 5 °C.
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 instructions.
