An updated NOM-001 will come into force in Mexico starting May 14, 2020.
Known formally as NOM-001-SCFI-2018, the new regulation replaces NOM-001-SCFI-1993. (NOM stands for “Norma Oficial Mexicana,” or Official Mexican Standard.)
NOM-001 covers the safety requirements for electronic devices manufactured, imported, commercialized, distributed, or leased in Mexico.
It applies to electronic equipment and accessories that use single-phase supply voltages up to 277 V AC at 60 Hz and/or three-phase voltages up to 480 V AC between lines at 60 Hz — as well as other energy sources, including batteries, energy accumulators, self-generation, and alternative power sources up to 500 V DC.
