Draft Details

This clause of Part 1 is replaced by the following.

This part of IEC 60335 specifies safety requirements for 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 International 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 are specified by 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 using flammable refrigerant in transcritical refrigeration systems;
domestic refrigerating appliances (IEC 60335-2-24);
split systems having a refrigerant charge of flammable refrigerant exceeding 150 g in any refrigerating circuit;
industrial refrigerating systems;
motor-compressors (IEC 60335-2-34);
commercial dispensing appliances and vending machines (IEC 60335-2-75);
commercial ice-cream appliances;
cold temperature rooms;
multiple refrigerated chambers with a remote motor-compressor.

1DV.1 D2 Modification to replace Clause 1 and Clause 1DV of the Part 1 and Clause 1 of the Part 2 with the following:
1DV.1.1 This part of UL/CSA 60335 specifies safety requirements for electrically operated commercial refrigerating appliances rated up to 15,000 volts ac or dc that have an incorporated MOTOR-COMPRESSOR or are Peltier-type (thermoelectric); refrigerating appliances that are supplied in two or more units for assembly as a single appliance in accordance with the manufacturer's instructions (PARTIAL UNITS), and PARTIAL UNITS intended for installation in a field erected system in accordance with:
– CSA C22.1, Canadian Electrical Code (CE Code) Part I, in Canada;
– NFPA 70, National Electrical Code (NEC), in the United States.

1DV.1.2 This standard also contains the requirements for:
a. REFRIGERATED DISPLAY and STORAGE CABINETS;
b. refrigerated trolley cabinets;
c. service counters and self-service counters;
d. blast chillers and blast freezers;
e. commercial ICE-MAKERS;
f. commercial refrigerators and freezers for use in fuel dispensing facilities (Annex 101.DVD);
g. FACTORY ASSEMBLED WALK-IN COOLER/FREEZER (WICF) (Annex 101.DVE);
h. PACKAGED REFRIGERATING UNITS (Annex 101.DVF);
i. PARTIAL UNITS (Annex 101.DVG);
j. dispensing units (Annex 101.DVH);
k. commercial refrigeration APPLIANCES NOT ACCESSIBLE TO THE GENERAL PUBLIC;
l. STIRLING REFRIGERATION SYSTEMS; and
m. laboratory refrigerators and freezers (for US only);
n. PARTIAL UNITS having a REFRIGERANT CHARGE of FLAMMABLE REFRIGERANT exceeding 150
g in any ISOLATED REFRIGERATING SEGMENT;
o. SELF-CONTAINED having a REFRIGERANT CHARGE of FLAMMABLE REFRIGERANT exceeding
150 g.
p. industrial refrigerating systems;

1DV.1.3 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. However, in general, it does not take into account children playing with the appliance or persons (including children) whose capabilities (including physical, sensory or mental), or lack of experience and knowledge prevent them from using the appliance safely without supervision or instruction.

1DV.1.4 This standard is not applicable to appliances that use refrigerants other than refrigerant safety groups as defined by ISO 817 or ANSI/ASHRAE 34 as follows:
a) A1;
b) B1 only if used in appliances installed for use within machinery rooms as defined in accordance with ANSI/ASHRAE 15 (USA) or CSA B52 (Canada), or outdoors only; and
c) A2L, A2, and A3, refrigerants.
1DV.1.5 All references to ISO 817 in this Part 2 also apply to ANSI/ASHRAE 34. ANSI/ASHRAE 34 shall take precedence over ISO 817, unless the refrigerant list in ISO 817 is more up-to-date than the similar refrigerant list
in ANSI/ASHRAE 34 in which case the refrigerant list in ISO 817 can be referenced.
NOTE 101 Attention is drawn to the fact that
a. for appliances intended to be used in vehicles or aboard ships or aircraft, additional requirements can be necessary;
b. in many countries, additional requirements are specified by national health authorities, the national authorities responsible for the protection of labor, the national water supply authorities and similar authorities.

NOTE 102 This standard does not apply to

a. appliances using FLAMMABLE REFRIGERANT in transcritical refrigeration systems;
b. domestic refrigerating appliances (UL 60335-2-24, CSA C22.2 No. 60335-2-24);
c. MOTOR-COMPRESSORS (UL 60335-2-34, CSA C22.2 No. 60335-2-34);
d. refrigerated vending machines or vending machines (UL 541 or UL 751; C22.2 No. 128);
e. professional ice-cream appliances (UL 621, CSA C22.2 No. 60335-2-118);
f. household ice-cream appliances (UL 60335-2-24, CSA C22.2 No, 60335-2-24)
g. laboratory refrigerators and freezers (for Canada only. In Canada, the applicable standard for laboratory refrigerators and freezers is CSA C22.2 No. 61010-2-011);
h. door panel assemblies (WICF);
i. add-on display case door(s);
j. appliances designed for comfort cooling and to regulate environmental temperatures within designated spaces.
1DV.1.6 Appliances not intended for normal household use, but which nevertheless may be a source of danger to the public, such as appliances intended to be used in supermarkets and retail stores, cold storage warehouses,commercial kitchens, and light industry are within scope of this standard.
