Guide to Norma Oficial Mexicana (NOM) 019-SCFI-1998: Ensuring the Safety of Data Processing Equipment
Norma Mexicana 019, also known as NOM-019-SCFI-1998, is an Official Mexican Standard that defines safety measures for data processing equipment such as computer mice or printers. This standard ensures data processing products are safe from electrical and mechanical hazards, thus safeguarding consumer well-being.
This article explains the scope and key compliance requirements for NOM-019-SCFI-1998, allowing you to sell your products on the Mexican market with confidence.
For background information, see: What Is NOM Certification for Mexico?
Scope
NOM-019-SCFI-1998 applies to data processing equipment and peripherals. It covers:
Electronic Data Processing Machines:
Portable devices such as laptops, notebooks, and palmtops
Microcomputers
Personal systems
Personal computers
Network terminals (Pc-net)
Servers
Devices that primarily operate with single processors and utilize technologies such as BUS-AT (ISA), EISA, MCA, NUBUS, BIOS, PCI, or PCMCIA as their main interface for expanding functionalities, including any current, future, or derivative versions of these technologies.
Associated Peripherals:
Printers
Plotters
External disk drives
External tape drives
Digitizing tablets
Image scanners
Optical readers
Monitors
Terminals
Computer Mice
Communication Equipment:
Devices used for electronic communication between data processing equipment and peripherals or local area networks (LAN), such as hubs, protocol converters, or routers designed for handling a single technology with a data bus not exceeding 100 MB/s and that are neither modular nor programmable.

The products listed are examples and not an exhaustive list. This standard entered into force in 1999 and continues to apply to both new and existing equipment marketed in Mexico.
Exempt Products
Products exempt from the NOM-019-SCFI-1998 include highly specialized equipment designed for professional or industrial use that are managed directly by businesses or institutions. These products are not covered by the standard due to their complex operational requirements and specialized applications, which are not typically accessible or marketed to the general public.
This exemption applies to advanced computing systems like workstations, scalable servers, supercomputers, and mainframes that require specific expertise to operate and maintain. Also excluded are associated peripherals such as high-capacity printers and large-format scanners, as well as specialized communication devices capable of handling high data bus speeds, modular configurations, and programmable functions.
Other exclusions include:
Devices like sensors, alarms, and other gear for identifying and alerting about potential hazards leading to harm or injury.
Fire suppression systems.
Standalone power supply equipment installed separately within a unit or network, such as motor generators, transformers, and cabling for alternative circuitry.
Electronic equipment for playing and recording audio frequency, such as dictating machines, recorders, and record players, that are not integrated into larger systems.
Data processing machinery intended for operation at altitudes exceeding 3000 meters above sea level.
Key Requirements of NOM-019
NOM-019-SCFI-1998 outlines several essential requirements that data processing equipment must meet in order to comply. Here is an overview
Safety Testing and Certification
Products must undergo prescribed safety testing methodologies
Testing must evaluate electrical insulation, fire resistance, temperature limits, mechanical hazards, and more.
Tests must be conducted under specified voltage, frequency, and environmental conditions
Products must be certified by an approved third-party testing laboratory like QIMA-NYCE.
Specific Safety Standards
Note: The following are examples of safety standards covered in NOM-019, but this is not an exhaustive list.
Construction Requirements
Internal wiring must be properly secured with protected insulation.
Safety circuits are designed to mitigate fire risks, electric shock, and high-energy hazards.
Insulating materials provide protection against shock and energy transfer.
Enclosures and covers require adequate mechanical strength.
Covers and openings are designed to prevent the entry of foreign objects.
Physical stability is ensured to prevent tipping over.
Limits on ionizing radiation emissions above certain voltage levels are covered.
Temperature, humidity, dielectric, and mechanical stress testing requirements are included
Power Connections and Wiring
Requirements for permanent wiring connections to branch circuits are specified.
Specifications are provided for detachable power cords and plugs.
Proper strain relief, bushings, and securing of cables are outlined.
Guidelines for internal wiring, splices, and interconnections are provided.
Separation of primary and secondary circuit wiring is covered.
Electromagnetic Compatibility
Maximum permissible limits are defined for electromagnetic emissions.
Emissions testing must ensure the product will not interfere with other electronics.
Both conducted and radiated emission limits are specified.
Product Marking
Compliant products must bear a certification mark demonstrating NOM-019 conformance.
Labeling must indicate manufacturer, model, electrical ratings, and safety warnings.
User instructions/manuals must be provided in Spanish.
By meeting the detailed safety, electromagnetic compatibility, and product marking criteria outlined in NOM-019-SCFI-1998, you can legally market your products for sale in Mexico.
