The requirements and testing methods set forth in this Standard apply to the following electronic devices for household use which use as their power source both the electrical energy supplied from public grids and from other energy sources such as cells, batteries or storage batteries which will be designed to operate at altitudes of up to 3 000 meters above sea level.

  • Radio receivers of one or more commercial frequency bands and one or more carrier/modulation modes.
  • Black and white and color television receivers, TV monitors.
  • Video projectors.
  • Sound amplifiers.
  • Magnetic-tape sound and image reproducers and/or recorders.
  • Manual and automatic record players.
  • Acoustic enclosures with built-in amplifier.
  • Remote controls for any of the devices covered by this Standard.
  • Signal amplifiers.
  • Microwave ovens.
  • Monitors.
  • Separate sources for supplying power to devices and for substituting cells and batteries.
  • Any combination of two or more of the above devices such as radio-phonographs, consoles and modular equipment.
  • Other electronic devices, implements, accessories and systems specifically intended for household use.
  • Electronic musical instruments.
  • Electronic accessories such as rhythm generators, tone generators (as an individual item of equipment), music synthesizers, and anything that is used with electronic and non/electronic instruments.
  • Video games and video-game generating devices that are hooked up to a TV.

Not covered by this standard are electronic devices whose power supply requires rated voltages of greater than:

  • 433 V (rms) between phases for three-phase power supplies.
  • 250 V (rms) in any other case.

Electronic devices specifically designed to operate at altitudes of greater than 3 000 meters above sea level, which are covered by the Standard for Devices and Components for Aeronautical Uses or Space Research.

Note: Products powered by voltages of 24 V or lower are also excused, according to Article 10, Annex 2.4.1, NOMs Agreement. However, UL may issue the corresponding compliance certificate upon the client’s request.

This standard sets forth the safety requirements that have to be met in the design and construction of electronic devices which use as their power source both electrical energy supplied by a public utility and other energy sources such as cells, batteries, storage batteries, etc., for the purpose of preventing and eliminating the following risks of bodily injury to the users, and of safeguarding their property:

1.1. Electrical discharges caused by leaks of electric current, or discharges between the devices and the human body.

1.2. Burns suffered by the human body as the result of accidental or deliberate contact with overheated accessible parts.

1.3. Bodily injury and material damage caused by the mechanical instability of the devices and/or by the functioning of their moving parts.

1.4. Bodily injury and material damage resulting from Fires caused by the devices in the course of their operation.

1.5. Pathological and genetic consequences of exposure of the human body to excessive doses of ionizing radiation emitted during the functioning of the devices, which include circuits with potentials equal to or greater than 16 kV (peak).
