The IEC is the world's leading organization that prepares and publishes International Standards for all electrical, electronic and related technologies — collectively known as"electrotechnology".

Wherever you find electricity and electronics, you find the IEC supporting safety and performance, the environment, electrical energy efficiency and renewable energies.

The IEC also manages conformity assessment systems that certify that equipment, systems or components conform to its International Standards.
