Overview

NOM-001-SCFI-1993 is Mexico's safety law regulating electronic devices that utilize electrical power sources. This standard extends to professional, scientific, and industrial equipment where no specific safety standard exists. As technology has advanced, the General Directorate of Standards has determined that this standard needs revision and updating.

Objectives

The primary goal of this standard is to set safety requirements for the design and construction of electronic equipment. These requirements aim to prevent:

• Electric shock
• Energy-related hazards
• Fire
• Thermal hazards
• Mechanical hazards
• Radiation
• Chemical hazards

Application

This Draft Official Mexican Standard pertains to electronic equipment and its accessories that draw electric power from public services, along with other energy sources such as batteries, accumulators, auto-generation, and alternative power sources. It applies to single-phase AC voltages ranging from 100 V to 277 V at 60 Hz and three-phase voltages from 173 V to 480 V between lines at 60 Hz, for operation up to 3,000 meters above sea level.
