The Full form of IEC is International Electrotechnical Commission. IEC is an international standards organization that prepares and publishes International Standards for all electrical, electronic and related technologies, collectively known as “Electrotechnology”. IEC standards cover a vast range of technologies from power generation, semiconductors, fibre optics, batteries, transmission and distribution to home appliances and office equipment, solar energy, marine energy and nanotechnology as well as many others. The IEC also manages three global conformity assessment systems that certify whether system, equipment or components conform to its International Standards. The IEC charter embraces all electrotechnologies including electronics, magnetics and electromagnetics, energy production and distribution, multimedia, telecommunication, electroacoustics, and medical technology, as well as associated general disciplines such as terminology and symbols, electromagnetic compatibility (by its Advisory Committee on Electromagnetic Compatibility, ACEC), measurement and performance, dependability, design and development, safety and the environment. The IEC is made up of members, called National Committees (NC), and each NC represents its nation’s electrotechnical interests in the IEC. This includes distributors, vendors, manufacturers, providers, consumers and users, all levels of professional societies, governmental agencies, and trade associations as well as standards developers from national standards bodies. Some NCs are public sector only, some are a combination of public and private sector, and some are private sector only.
