The International Electrotechnical Commission held its inaugural meeting on 26 June , following discussions among the British Institution of Electrical Engineers , the American Institute of Electrical Engineers , and others, which began at the Paris International Electrical Congress,[ citation needed ] and continued with Colonel R. Crompton playing a key role.
In , it published a multilingual international vocabulary to unify terminology relating to electrical, electronic and related technologies. This effort continues, and the International Electrotechnical Vocabulary the on-line version of which is known as the Electropedia remains an important work in the electrical and electronic industries.
Currently, 86 countries are IEC members while another 87 participate in the Affiliate Country Programme, which is not a form of membership but is designed to help industrializing countries get involved with the IEC.
Originally located in London , the Commission moved to its current headquarters in Geneva in The work is done by some 10, electrical and electronics experts from industry, government, academia, test labs and others with an interest in the subject. IEC standards have numbers in the range — and their titles take a form such as IEC Graphical symbols for use on equipment.
In addition, it works with several major standards development organizations, including the IEEE with which it signed a cooperation agreement in , which was amended in to include joint development work. IEC standards adopted by other certifying bodies may have some noted differences from the original IEC standard. This includes manufacturers, providers, distributors and vendors, consumers and users, all levels of governmental agencies, professional societies and trade associations as well as standards developers from national standards bodies.
National committees are constituted in different ways. Some NCs are public sector only, some are a combination of public and private sector, and some are private sector only.
IEC Member countries include: .
Give feedback IEC series explains some common principles that can be used in the transmission of safety-relevant messages among participants within a distributed network which use fieldbus technology in accordance with the requirements of IEC series for functional safety. These principles are based on the black channel approach. They can be used in various industrial applications such as process control, manufacturing automation and machinery. This part and the IEC x parts specify several functional safety communication profiles based on the communication profiles and protocol layers of the fieldbus technologies in IEC , IEC and the IEC series. These functional safety communication profiles use the black channel approach, as defined in IEC
