List of IEC technical committees

IEC or International Electrotechnical Commission is a standards-making body in the field of electrical and electronics technologies. The IEC works with National Committees in different countries in preparing and maintaining standards in this space. IEC is one of the oldest standards making bodies in existence.


The IEC standards making process, similar to many other standards making processes, is handled by various technical committees or TC as they are called. The TCs are the key bodies that drive the standardization and comprise experts from the national committees and are a completely voluntary effort. IEC has more than 11,000 technical experts working on standards voluntarily.

This list is intended to detail the various technical committees of IEC, the scope of the committees, their key members and the key relevance and outputs of these committees.

Each technical committee and its standardization efforts is vast and is carried out by various working groups within the technical committees.

The list below was last updated on 27 October 2011. For the most up-to-date list visit the IEC website.
