What products use IEC International Standards?

The IEC publishes International Standards for the millions of devices that contain electronics or use, produce, or store electricity.


These include such products as:

on/off sign

  • Nanotechnology, superconductivity
  • Electronic components, microchips, circuit boards, computers
  • Plugs and sockets, cables, switches, insulating materials
  • All kinds of batteries and fuel cells
  • Household equipment such as fridges, hair dryers, microwave ovens, toasters, TVs
  • Private and public transportation, including metros, electric cars, trains, buses, planes, ships
  • Electric power generation: Smart Grid, photovoltaics, wind turbines, marine energy, power lines, transformers and much, much more.

+/- sign on batteries

The work is done in TCs and SCs (Technical Committees and Subcommittees) by close to 10 000 experts in more than 1 000 Working Groups.


The IEC not only defines safety parameters for these products but also those of efficiency, interconnectivity (how products work with each other), quality and performance, how a device interferes with others (EMC), how environmentally-friendly it has been produced and how it should be recycled. It also prepares symbols, such as the "on/off" sign and + /– on batteries, and it helps engineers to speak the same language (electrotechnical vocabulary).
