UL Standard for Safety Audio, Video and Similar Electronic Apparatus – Safety Requirements
|Publication Date:||30 June 2003|
DU 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. It also covers COMMERCIAL APPARATUS and PROFESSIONAL APPARATUS which may 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 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;
- SUPPLY APPARATUS intended to supply other apparatus covered by the scope of this standard;
- ELECTRONIC MUSICAL INSTRUMENTS, and electronic accessories such as rhythm generators, tone generators, music tuners and the like for use with electronic or non-electronic musical instruments;
- audio and/or video educational apparatus;
- video projectors;
NOTE 1 Film projectors, slide projectors, overhead projectors are covered by UL 122
- video cameras and video monitors;
- household video games and flipper games;
- juke boxes;
- household electronic gaming and scoring machines;
NOTE 2 Video games, flipper games and gaming machines and other amusement games for commercial use are covered by UL 22
- teletext equipment;
- record and optical disc players;
- tape and optical disc recorders;
- antenna signal converters and amplifiers;
- satellite receiver antenna positioners;
NOTE 2A UHF and VHF antenna rotators are covered by UL 150
- Citizen's Band apparatus;
- apparatus for IMAGERY;
- electronic light effect apparatus;
- apparatus for use in alarm systems;
NOTE 2B Includes cameras, stop motion recorders and the like used in alarm systems. This Standard does not cover the investigation of the actual alarm system.
- intercommunication apparatus, using low voltage MAINS as the transmission medium;
- cable head-end receivers;
- multimedia apparatus;
NOTE 3 The requirements of UL 60950-1 may also be used to meet the requirements for safety of multi media apparatus (see also IEC Guide 112 )
- professional general use amplifiers, record or disc players, tape players, recorders, and public address systems;
- professional sound/video systems.
NOTE 4 The requirements of UL 1419 may also be used to meet the requirements for safety of PROFESSIONAL APPARATUS.
- electronic flash apparatus for photographic purposes are covered by UL 122
MAINS connected apparatus covered by this standard is intended for installation in compliance with the National Electrical Code, ANSI/NFPA 70.
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.
DU 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 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.
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.
DU 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.
DR 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-handing space after installation are subject to this requirement.
