scope:

This standard is applicable to the safety of electrical and electronic equipment within the field of audio, video, information and communication technology, and business and office machines with a rated voltage not exceeding 600 V. This standard does not include requirements for performance or functional characteristics of equipment. NOTE 1 Examples of equipment within the scope of this standard are given in Annex A. This standard is also applicable to components, subassemblies and accessories, including for example external power supplies, intended for use in or with this equipment. Such components, subassemblies and accessories need not comply with every requirement of the standard, provided that the complete equipment, using such components, subassemblies and accessories, does comply. This standard does not apply to power supply systems which are not an integral part of the equipment, such as motor-generator sets, battery backup systems and distribution transformers. This standard specifies safeguards for ordinary persons, instructed persons, and skilled persons. Additional requirements may apply for equipment that is clearly designed or intended for use by children or specifically attractive to children. NOTE 2 In Australia, the work conducted by an instructed person or a skilled person may require formal licensing from regulatory authorities. This standard assumes an altitude of 2 000 m unless specified otherwise by the manufacturer. This standard does not apply to equipment to be used in wet areas. Additional requirements may apply. Equipment intended for outdoor installation shall, in addition to the requirements of this standard, comply with the relevant requirements given in IEC 60950-22. This standard does not address: - manufacturing processes except safety testing; - injurious effects of gases released by thermal decomposition or combustion; - disposal processes; - effects of transport (other than as specified in this standard); - effects of storage of materials, components, or the equipment itself; - the likelihood of injury from particulate radiation such as alpha particles and beta particles; - the likelihood of thermal injury due to radiated or convected thermal energy; - the likelihood of injury due to flammable liquids; - the use of the equipment in oxygen-enriched or explosive atmospheres; - exposure to chemicals other than as specified in Clause 7; - electrostatic discharge events; - environmental aspects; - requirements for functional safety. NOTE 3 For specific functional and software safety requirements of electronic 434 safety-related systems (for example, protective electronic circuits), see IEC 61508-1.
