This document sets the general and dimensional interchangeability requirements for plugs, socket-outlets, connectors and appliance inlets with arcuate contacts of standardized configurations (hereinafter referred to as accessories), with a rated operating voltage not exceeding 600 V AC at a frequency of 50 Hz and 60 Hz and with rated currents of 20 A and 30 A, primarily intended for commercial use indoors, in conditions where the presence of water is negligible.

This document applies to accessories for use when the ambient temperature is normally within the range of –25 °C to +40 °C. These accessories are intended to be connected to cables of copper or copper alloy only.

Interchangeability requirements are defined for IP20 accessories.

NOTE The conditions of use indoors are based on the limitations given by IEC 60364-5-51:2005, Table 51A, AD1.

Socket-outlets or appliance inlets incorporated in or fixed to electrical equipment are within the scope of this document.

1DV [D1] Modify the “Scope” first paragraph by replacing with the Clauses 1DV.1, 1DV.2:

1DV.1 This Standard covers the general and dimensional interchangeability requirements for plugs, connectors, receptacles, adaptors, appliance inlets, current taps and similar devices with arcuate contacts of standardized configurations (hereinafter referred to as accessories), with a rated operating voltage not exceeding 600 V AC at a frequency of 50 Hz and 60 Hz and with rated currents of 20 A and 30 A, and intended for use in accordance with CE Code, Part I.

1DV.2 This Standard does not apply to the following products:

a) Straight-blade attachment plugs, receptacles, cord connectors, and inlets, covered by CSA C22.2 No 42;
b) Cord sets and power supply cords covered by CSA C22.2 No 21;
c) Cord reels and multi-outlet assemblies covered by CSA C22.2 No 308;
d) Devices having male or female screw shells, covered by CSA C22.2 No 43;
e) Receptacles, attachment plugs, connectors and adaptors of the special use types covered by CSA C22.2 No. 182.1, CSA C22.2 No. 182.2, CSA C22.2 No. 182.3 and CSA C22.2 No. 182.4;
g) Devices intended for hazardous locations covered by CSA C22.2 No 25 & CSA C22.2 No 30;
i) Devices incorporating ground-fault circuit interruption circuitry, covered by CSA C22.2 No 144.1;

This section of IEC 60947-5 provides detailed specifications relating to the electrical and mechanical construction of emergency stop devices with mechanical latching function and to their testing.

This standard is applicable to electrical control circuit devices and switching elements which are used to initiate an emergency stop signal. Such devices may be either provided with their own enclosure, or installed according to the manufacturer’s instructions.

This standard does not apply to:
– emergency stop devices for non-electrical control circuit, for example hydraulic, pneumatic;
– emergency stop devices without mechanical latching function.

An emergency stop device may also be used to provide an emergency switching off function.

This standard does not deal with any specific requirements on noise as the noise emission of electrical emergency stop devices with mechanical latching function is not considered to be a relevant hazard.

This clause of Part 1 is replaced by the following.

This International Standard specifies safety requirements for electrically operated commercial refrigerating appliances that have an incorporated compressor or that are supplied in two units for assembly as a single
appliance in accordance with the manufacturer’s instructions (split system).

1DV.1 D2 Modification to replace the second paragraph in Clause 1 with the following:

This Standard specifies safety requirements for electrically operated commercial refrigerating appliances that have an incorporated compressor or that are supplied in two units for assembly as a single appliance in  accordance with the manufacturer’s instructions (split system) and intended for use 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.

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.

As far as is practicable, this standard deals with the common hazards presented by these types of appliances.

It does not cover those features of construction and operation of refrigerating appliances which are dealt with in ISO standards.

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 national authorities. 

NOTE 103 This standard does not apply to
– domestic refrigerating appliances (IEC 60335-2-24)
– industrial refrigerating systems; – motor-compressors (IEC 60335-2-34);
– commercial dispensing appliances and vending machines (IEC 60335-2-75);
– commercial ice-cream appliances;
– commercial ice makers;
– cold temperature rooms;
– multiple refrigerated chambers with a remote compressor.

NOTE 104 Appliances with a charge of more than 150 g of FLAMMABLE REFRIGERANT in each separate refrigerant circuit are not covered by this standard. For appliances with a charge greater than 150 g of FLAMMABLE REFRIGERANT in each refrigerant circuit and for the installation, ISO 5149 may be applied.

Consequently, such appliances cannot be assessed for safety using this part 2.

1DV.2 D2 Modification to add the following after the second paragraph:

This standard also contains the requirements for:
– commercial refrigerators and freezers for use in fuel dispensing facilities (Annex 101.DVD);
– factory assembled walk in coolers (Annex 101.DVE);
– refrigerating units (Annex 101.DVF); – PARTIAL UNITS
(Annex 101.DVG); and
– dispensing units (Annex 101.DVH).
