UL 6500

Standard for Audio/Video and Musical Instrument Apparatus for Household, Commercial, and Similar General Use

1.1.1 This International Standard applies to electronic apparatus designed to be fed from the MAINS or from a SUPPLY APPARATUS 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 concerns only safety aspects of the above apparatus; it does not concern other matters, such as style or performance.

For above-mentioned apparatus, which are fed from a supply source other than the MAINS or from a SUPPLY APPARATUS , and which contain a LASER SYSTEM or produce an internal OPERATING VOLTAGE greater than 4000 V (peak), this standard applies as far as applicable.

NOTE 1 - In Australia, Canada, Denmark, Japan, Rumania, South Africa, United States of America and United Kingdom this standard is, where relevant, used as a guide for the testing of battery operated apparatus.

This standard applies to the above-mentioned apparatus, if it is 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;


-     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;

-     video cameras and video monitors;

-     household video games and flipper games;

NOTE 2 - Video and flipper games for commercial use are covered by IEC 60335-2-82 [7] UL 22

Figures in square brackets refer to the bibliography given in annex p.

-     juke boxes;

-     household electronic gaming and scoring machines;

NOTE 3 - Electronic gaming and scoring machines for commercial use are covered by IEC 60335-2-82 [7] UL 22

-     teletext equipment;

-     record and optical disc players;

-     tape and optical disc recorders;

-     antenna signal converters and amplifiers;

-     satellite receiver antenna positioners;

-     Citizen's Band apparatus;

-     apparatus for IMAGERY ;

-     light effect apparatus;

-     intercommunication apparatus, using low voltage MAINS as the transmission medium.

-     video apparatus intended for entertainment purposes in health-care facilities;

-     cellular phones, wireless modems, and similar transceiving devices;

-     audio or video apparatus that are used with a battery supply.

MAINS connected apparatus covered by this standard is intended for installation in compliance with the National Electrical Code, ANSI/NFPA 70.

Any undated reference to a code or a standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard.

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 2000 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 2000 m above sea level, additional requirements may be necessary.

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 This standard does not apply to the following apparatus, except where this standard is referenced in the relevant standard:

-     apparatus falling within the scope of IEC 60950,

-     dictation apparatus,

-     projectors not mentioned in 1.1.1, for example film projectors, slide projectors, overhead projectors, epidiascopes. (See IEC 60335-2-56 [6].)

1.1.6 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.
