IEC

INTERNATIONAL ELECTROTECHNICAL COMMISSION

IEC's activities, collectively known as electrotechnology, cover all electrical, electronic and associated technologies in the areas of power generation, transmission and distribution, medical equipment, semiconductors, fibre optics, nanotechnology and renewable energies. In addition to providing an excellent framework for improving safety and optimizing energy, IEC standards support trade between countries by providing a reference for the functioning of the World Trade Organization (WTO) Agreement on Technical Barriers to Trade.
