Frequently Asked Questions

WG 4 is a Technical Committee within the International Electrotechnical Commission (IEC). It is named "TC 21/SC 21A/WG 4". This committee has published 460 standards.

WG 4 develops IEC standards in the area of Information technology. Currently, there are 460 published standards from this technical committee.

The International Electrotechnical Commission (IEC) is the world's leading organization for the preparation and publication of international standards for electrical, electronic, and related technologies. Founded in 1906, the IEC provides a global platform for companies, industries, and governments to meet, discuss, and develop the international standards they require.

A Technical Committee (TC) in IEC is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
