This standard is applicable to mains-powered or battery-powered information technology equipment, including electrical business equipment and associated equipment, with a RATED VOLTAGE not exceeding 600 V and designed to be installed in accordance with the Canadian Electrical Code, Part I, CSA C22.1-12; General Requirements - Canadian Electrical Code, Part II, CSA C22.2 No. 0-10; the National Electrical Code, NFPA 70-2014; and the National Electrical Safety Code, IEEE C2-2012.The standard is also applicable to equipment, unless otherwise identified by a marking or instructions, designed to be installed in accordance with Article 645 of the National Electrical Code, ANSI/NFPA 70, and the Standard for the Protection of Information Technology Equipment, NFPA 75-2013.See Annex nae for examples of and references to regulatory requirements that apply to this equipment.This standard is also applicable to such information technology equipment:
This part of IEC 60950 is also applicable to:
- designed for use as telecommunication terminal equipment and TELECOMMUNICATION NETWORK infrastructure equipment, regardless of the source of power;
- designed and intended to be connected directly to, or used as infrastructure equipment in, a CABLE DISTRIBUTION SYSTEM, regardless of the source of power;
- designed to use the AC MAINS SUPPLY as a communication transmission medium (see Clause 6, Note 4 and 7.1, Note 4).
NOTE 1 Examples of aspects with which uninstalled components, subassemblies, and accessories may not comply include the marking of the power rating and access to hazardous parts.NOTE 2 This standard may be applied to the electronic parts of equipment even if that equipment does not wholly fall within its Scope, such as large-scale air conditioning systems, fire detection systems and fire extinguishing systems. Different requirements may be necessary for some applications.This standard specifies requirements intended to reduce risks of fire, electric shock or injury for the OPERATOR and layman who may come into contact with the equipment and, where specifically stated, for a SERVICE PERSON.This standard also specifies requirements intended to reduce risks from acoustic outputs at communication receivers and similar devices used for voice telecommunication, regardless of transmission medium (e.g., TELECOMMUNICATION NETWORK, CABLE DISTRIBUTION NETWORK, wireless network). See Annex nad.This standard is intended to reduce such risks with respect to installed equipment, whether it consists of a system of interconnected units or independent units, subject to installing, operating and maintaining the equipment in the manner prescribed by the manufacturer.Examples of equipment that is in the scope of this standard are:
- components and subassemblies intended for incorporation in this equipment. Such components and subassemblies need not comply with every requirement of the standard, provided that the complete equipment, incorporating such components and subassemblies, does comply;
- external power supply units intended to supply other equipment within the scope of this part of IEC 60950;
- accessories intended to be used with equipment within the scope of this part of IEC 60950.

Requirements additional to those specified in this standard may be necessary for:
NOTE Attention is drawn to the fact that authorities of some countries impose additional requirements.
- equipment intended for operation in special environments (for example, extremes of temperature; excessive dust, moisture or vibration; flammable gases; and corrosive or explosive atmospheres);
- electromedical applications with physical connections to the patient;
- equipment intended to be used in vehicles, on board ships or aircraft, in tropical countries, or at altitudes greater than 2 000 m;
- equipment intended for use where ingress of water is possible; for guidance on such requirements and on relevant testing, see Annex t.
This standard does not apply to:
Battery backup systems that are not an integral part of STATIONARY EQUIPMENT, such as provided in separate cabinets, are subjected to the appropriate standard for the battery backup systems, such as the Standard for Batteries for Use in Light Electric Rail (LER) Applications and Stationary Applications, UL 1973.NOTE See Figures 1.1 and 1.2 of UL 1973 for more information on independent electric energy storage systems (EESS) covered by UL 1973, which can consist of both low voltage and hazardous voltage subsystems, battery management, thermal management, and related features and safeguards. When interconnected with AV, IT and CT Equipment, and typically used in conjunction with an uninterruptible power supply (UPS), such EESS typically serve as short term substitution of the mains supply during power outages and similar disturbances.
- power supply systems which are not an integral part of the equipment, such as motor-generator sets, battery backup systems and distribution transformers;
- building installation wiring;
- devices requiring no electric power.
