Seguridad de equipo de procesamiento de datos. (Data-Processing Equipment Safety).
This Norma Oficial Mexicana (‘NOM,’ Official Mexican Standard in English) sets out safety requirements to be met by all peripheral Data Processing Equipment or related equipment marketed in Mexico.
Requirements and testing methods in this NOM apply, including but not limited, to the following products:
- Electronic Data-Processing (EDP) Machines identified as portable machines (laptop, notebook, palmtop), Microcomputers, Personal Systems, Personal Computers (PC), Computers for personal use, Network Terminals (PC-Net), Servers or equivalent equipment. They should also meet the following two characteristics:
- They should be uniprocessors;
- They should use BUS-AT (ISA) or EISA or MCA or NUBUS or BIOS or PCI or PCMI or PMCIA technology in all their current or future versions or versions derived from them, such as their main operating BUS.
- Peripherals associated with machines indicated in letter (a) of this section such as printers, plotters, external disk drives, external tape drives, digitizer tablets, image scanners, optical readers, monitors and terminals.
- Equipment used for electronic communication between data processing equipment and peripheral equipment, Local Area Networks (LAN) such as hubs, protocol converters or routers, among others, which are designed to manage a single technology whose data BUS is not greater than 100 MBs, or which have any of the following characteristics:
- Non-modular type;
- Not easily programmable.
Highly Specialized Equipment not specified above and not subject to direct commercialization to the general public but to business users or institutions installing, operating and updating such equipment directly or in joint liability with the supplier company, as well as the equipment below, are excluded from the scope of this NOM:
- Computers having multi-process architecture, regardless of the type and number of processors used, such as: workstations, scalable servers not meeting number 1.1, super-servers, minicomputers, corporate systems, enterprise systems or business computer systems, mid-range systems, fault tolerant systems, non-stop systems, high-performance systems, supercomputers and macrocomputers.
- Peripherals associated with machines indicated in number 1.2, such as printers, plotters, external disk drives, external tape drives, digitizer tablets, image scanners, optical readers, monitors, terminals or control or adaptive units.
- Equipment used for electronic communication between data processing equipment and peripheral equipment, Local Area Networks (LAN), among others, such as hubs, protocol converters or routers, complying with two of the following characteristics:
- They should have a data BUS greater than or equal to 100 MB;
- They should have a modular structure designed to change their characteristics regarding the use of different technologies;
- They should be programmable and should use various communication protocols, and/or allow monitoring of the Local Area Network (LAN).
- Sensors, Alarms and other equipment for detection and signaling of conditions that may cause personal injury or damage.
- Fire Suppression Systems.
- Electric Power Supply Equipment separately installed in a unit or system (e.g. motor generators, transformers and branch circuit supply wiring).
- Electronic Sound Recording and Reproduction Equipment not connected to systems such as dictation machines, recorders and record players.
- Data-Processing Equipment specifically designed to operate at altitudes higher than 3 000 m above sea level.
- Word-Processing Machines
- Analogue or Hybrid Automatic Data-Processing Machines
- Portable Digital Automatic Data-Processing Machine, weighing equal to or less than [sic] kilograms, and comprising at least one CPU, one keyboard and one screen
- Combined Units with an input/output unit, as well as those presented in the form of a system.
- Digital Processing Units (DPU) including memory units, input unit and output unit
- Color and Monochrome Monitors with cathode ray tubes
- Monitors other than cathode ray tubes with a 14” visual field measured diagonally
- Laser Printers, LED Printers, Inkjet Printers, Thermal Transfer Printers, and Ion Deposition Printers
- Combined Input and Output Units (interfaces)
- Optical Readers (Scanners) and Magnetic Ink Character Recognition (MICR) Reader, Barcodes
- LAN devices (hubs, routers, distributors, repeaters)
- Control Adaptive Units and Interfaces
- Multimedia Systems
- Digital Cameras
- Disk Drives for LANs, Disk Control or Adaptation, among others, with their own channels
- Memory Units in their own channels
- Peripherals such as keyboards, mice, remote-control pointers, digitizing pads, etc.
- CD-ROM Drives
- Home Medical Equipment or Self-Diagnosis Equipment controlled by data-processing equipment
- Other equipment resulting from new technological developments
In case of High Specialty Equipment (HSE – Highly Specialized Equipment), UL de Mexico offers HSE opinion services. Issuing this opinion does not give you any right to use UL de Mexico’s conformity mark, as it indicates that equipment units are excluded from the scope covered by NOM-019-SCFI-1998, in accordance with number 1.2 thereof.
Note: Products with 24 V or less voltages are also excluded, in accordance with Article 10 in Appendix 2.4.1 to the NOM Agreement. UL, however, may issue the corresponding certificate of conformity upon customer’s request.
