GB/T 4706.102-2024 Safety of household and similar electrical appliances - Part 102 : Particular requirements for commercial refrigerating appliances and ice-makers with an incorporated or remote refrigerant unit or motor-compressor
1 Scope
This clause of GB/T 4706.1-2024 is replaced by the following.
This standard specifies safety requirements for electrically operated commercial refrigerating appliances and ice-makers with a household and similar incorporated or remote refrigerant unit or motor-compressor.
This standard is applicable to the electrically operated commercial refrigerating appliances and ice-makers that have an incorporated motor-compressor or that are supplied in two units for assembly as a single appliance in accordance with the instructions (split system).
Note 101: Examples of appliances that are within the scope of this standard are
– refrigerated display and storage cabinets;
– refrigerated trolley cabinets;
– service counters and self-service counters;
– blast chillers and blast freezers;
– commercial ice-makers.
As far as is practicable, this standard deals with the common hazards presented by these types of appliances including those that use flammable refrigerants and appliances employing R-744 refrigerant.
This standard is not applicable to appliances with a mass of flammable refrigerant exceeding the limits specified in 22.110 or to appliances with that use refrigerants with a toxicity classification of B according to ISO 817.
It does not cover those features of construction and operation of refrigerating appliances that are dealt with in ISO standards.
Note 102: Attention is drawn to the fact that
– for appliances intended to be used in vehicles or aboard ships or aircraft, additional requirements can be necessary;
– in many countries, additional requirements may be specified by national management authorities.
Note 103: This standard does not apply to
– appliances using flammable refrigerant in transcritical refrigeration systems;
– domestic refrigerating appliances (GB/T 4706.13);
– split systems having a refrigerant charge of flammable refrigerant exceeding 150 g in any refrigerating circuit;
– industrial refrigerating systems;
– motor-compressors (GB/T 4706.17);
– commercial dispensing appliances and vending machines (GB/T 4706.72);
– commercial ice-cream appliances;
– cold temperature rooms;
– multiple refrigerated chambers with a remote motor-compressor.
