Description of content: The notified draft Mexican Official Standard covers electronic equipment and related accessories powered by mains electricity, with single-phase supply voltages up to 277 V AC at 60 Hz and/or three-phase voltages up to 480 V AC at 60 Hz, or by other energy sources such as batteries or accumulators, self-generated energy, or alternative power sources up to 500 V AC.
The text covers new, second-line, discontinued, rebuilt, reconditioned, used or second-hand electronic equipment.
The requirements and test methods set out in this draft Mexican Official Standard apply to electronic equipment and/or systems covered by Chapter 5 of the text and to the following types of electronic equipment and/or systems that are powered by mains electricity or other energy sources, such as batteries and accumulators:
- Radio receivers with one or more commercial frequency bands and one or more carrier modulation modalities;
- Television screens of any sort;
- Video projectors, other than those classed as information technology equipment (see Mexican Official Standard NOM-019-SCFI-1998);
- Sound and/or image amplifiers;
- Audio and image reproducers and/or recorders incorporating any form of technology (acetate, magnetic tape, digital discs, digital memories, etc.), such as photographic cameras, dictation devices, voice recorders, modular equipment, home cinema equipment, sound bars, etc.;
- Acoustic boxes with embedded amplifiers;
- Remote controls;
- Antenna signal converters and amplifiers;
- Closed-circuit television monitors and entertainment monitors;
- Separate power supply units for powering devices and replacing batteries, electronic UPS systems and battery chargers;
- Electronic musical instruments;
- Electronic accessories such as rhythm generators, tone generators (as stand-alone equipment), synthesizers, musical items, and anything that is used with electronic and non-electronic instruments;
- Videogames and videogame-generating devices that are coupled to a TV set or monitor;
- Electronic games;
- Electromedical equipment and professional electronic equipment (photographic cameras, video cameras);
- Active and passive horns and loudspeakers;
- Alarm and video surveillance systems;
- Communication systems such as walkie-talkies, even where considered toys;
- Lighting systems for nightclubs, including strobe, LED and laser lights;
- Single-purpose or multi-purpose measuring equipment, such as voltmeters, multi-meters and oscilloscopes, etc.;
- Cash machines and cash registers;
- Educational audio and/or video equipment;
- Video cameras;
- Jukeboxes;
- Antenna positioners;
- Citizens' band (CB) radio equipment;
- Imaging equipment;
- Light-effect electronic equipment (e.g. strobe or rhythmic lighting);
- Intercom equipment using the low voltage network as a means of transmission;
- Cable television receivers;
- Multimedia equipment;
- Electronic flash apparatus;
- Amusement and personal service machines;
- Microwave ovens.
The above list is non-exhaustive, which means that new electronic products deriving from new electronic technologies may be added.
This draft Mexican Official Standard also applies to external power sources that are used in conjunction with the electronic equipment covered by the text, and which are marketed, distributed or supplied individually or as part of an end-use product in a single package, and to external power sources that are marketed individually for information technology equipment covered by the scope of Mexican Official Standard NOM-019-SCFI-1998, in both cases for use with DC supplies up to 250 V and AC supplies up to 1,000 V at 60 Hz.
This draft Mexican Official Standard does not apply to:
- Power systems that are not an integral part of the equipment, such as motor generators;
- Electrical wiring in buildings;
- Devices not requiring electrical power;
- Equipment designed for use in special environments (e.g. extreme temperatures, excessive dust, humidity or vibrations, inflammable gases and corrosive or explosive atmospheres);
- Equipment to be used or installed on board boats or aeroplanes;
- Equipment covered by the scope of Mexican Official Standards NOM-019-SCFI-1998 and NOM-016-SCFI-2001, or any Standards replacing them;
- External power sources for outdoor use, power sources for lighting, and power sources exceeding the limits established in the objective and scope;
- Internal power sources;
- External power sources exceeding 250 W.
The scope of this draft Mexican Official Standard excludes all electronic equipment that is required to comply with a specific Mexican Official Standard.
