Límites máximos de potencia eléctrica para equipos y aparatos que demandan energía en espera. Métodos de prueba y etiquetado. (Maximum Electric Power Limits for Equipment and Appliances Demanding Standby Power. Testing Methods and Labeling).

This Norma Oficial Mexicana (‘NOM,’ Official Mexican Standard in English) sets forth the maximum electric power limits for equipment and appliances demanding standby power. It also sets out the type of information on the Energy Efficiency Label to be borne by products subject to this NOM, which are marketed in Mexico. Likewise, it meets the need for these products to promote efficient use and energy saving.

This NOM applies to Electronic Appliances and equipment below:

  • Digital Television Adapters (DTA)
  • Decoders with television signal reception via cable, satellite or Internet Protocol (IP)
  • Image Reproduction Equipment such as printers, scanners, photocopiers and multi-function printers
  • Microwave Ovens
  • independent Detachable or Non-Detachable Audio Reproduction Equipment for one or more sound functions
  • Home Video or Theater Reproduction Equipment in digital versatile disc (DVD) or Blue-ray disc format
  • Television Sets with a light-emitting diode (LED) display, liquid-crystal display (LCD), plasma display panel (PDP), and organic light-emitting diodes (OLED) display, in single-phase power supply voltages from 100 to 277 VCA and 50 Hz or 60 Hz, manufactured or imported to be marketed in the country.


This NOM does not apply to equipment or appliances included in the scope of another NOM on energy efficiency, or to equipment or appliances requiring as power supply an external source for its operation or not having a standby mode as operating condition because of its operating nature. Photocopiers, Printers and Multifunctional Equipment weighing more than 15 kg, stated by the manufacturer, are exempt from compliance with this NOM. Highly Specialized Equipment not directly sold to the public and intended to be commercialized for special purposes in accordance with the needs stated in a contract including commercial information, warranty and installation, are exempt from compliance because they are installed by the supplier’s qualified technical personnel.
