1.1.1 This International Safety Standard applies to electronic apparatus designed to be fed from the MAINS, from a SUPPLY APPARATUS, from batteries or from REMOTE POWER FEEDING and intended for reception, generation, recording or reproduction respectively of audio, video and associated signals. It also applies to apparatus designed to be used exclusively in combination with the above-mentioned apparatus.
This standard primarily concerns apparatus intended for household and similar general use. but It also covers COMMERCIAL APPARATUS and PROFESSIONAL APPARATUS which may also be used in places of public assembly such as schools, theatres, places of worship and the workplace. PROFESSIONAL APPARATUS intended for use as described above is also covered unless falling specifically within the scope of other standards may be evaluated to requirements in this standard, or to the requirements in UL 1419.
This standard concerns only safety aspects of the above apparatus; it does not concern other matters, such as style or performance.
This standard applies to the above-mentioned apparatus, if designed to be connected to the TELECOMMUNICATION NETWORK or similar network, for example by means of an integrated modem.
Some examples of apparatus within the scope of this standard are:
– receiving apparatus and amplifiers for sound and/or vision;
– independent LOAD TRANSDUCERS and SOURCE TRANSDUCERS;

MAINS connected apparatus covered by this standard is intended for installation in compliance with the National Electrical Code, ANSI/NFPA 70.
1.1.2 This standard applies to apparatus with a RATED SUPPLY VOLTAGE not exceeding
– 250 V a.c. single phase or d.c. supply;
– 433 V a.c. in the case of apparatus for connection to a supply other than single-phase.
1.1.3 This standard applies to apparatus for use at altitudes not exceeding 2 000 m above sea level, primarily in dry locations and in regions with moderate or tropical climates.
For apparatus with protection against splashing water intended for outdoor use, additional requirements are given in annex a.
For apparatus to be connected to TELECOMMUNICATION NETWORKS, additional requirements are given in annex b.
For apparatus intended to be used in vehicles, ships or aircraft, or at altitudes exceeding 2 000 m above sea level, additional requirements may be necessary.
NOTE See table A.2 of IEC 60664-1.
Requirements, additional to those specified in this standard, may be necessary for apparatus intended for special conditions of use.
1.1.4 For apparatus designed to be fed from the MAINS, this standard applies to apparatus intended to be connected to a MAINS supply with transient overvoltages not exceeding overvoltage category II according to IEC 60664-1.
For apparatus subject to transient overvoltages exceeding those for overvoltage category II, additional protection may be necessary in the MAINS supply of the apparatus.
1.1.5 Certain apparatus covered by the requirements in this standard are also required to comply with applicable requirements in other appropriate standards because of their intended end use applications or environmental conditions.
1.1.6 Audio and video apparatus with nonmetallic enclosures, intended to be installed in air-handling spaces shall additionally comply with the requirements in UL 2043.
NOTE Apparatus such as dome cameras and public address system speakers having nonmetallic enclosures that extend inside the air-handling space after installation are subject to this requirement.
