Frequently Asked Questions

TC 64 is a Technical Committee within the International Electrotechnical Commission (IEC). It is named "Electrical installations and protection against electric shock" and is responsible for: To prepare International standards: concerning protection against electric shock arising from equipment, from installations and from systems without limit of voltage; for the design, erection foreseeable correct use, proper functioning and verification of all kind of electrical installations at supply voltage up to 1 kV AC. or 1,5 kV DC., except those installations covered by the following IEC committees: TC 9, TC 18, TC 44, TC 97, TC 99; in co-ordination with TC 99, concerning requirements additional to those of TC 99 for the design, erection and verification of electrical installations of buildings above 1 kV up to 35 kV. The object of the standards shall be: to lay down requirements for installation and co-ordination of electrical equipment to lay down basic safety requirements for protection against electric shock for use by technical committees to lay down safety requirements for protection against other hazards arising from the use of electricity (e.g. thermal effects, overcurrent, fault currents, voltage disturbances) to specify the operational characteristics and performance criteria necessary for selection of equipment for installation applications to give general guidance to IEC member countries that may have need of such requirements and to facilitate international exchanges that may be hampered by differences in national regulations. The standards will not cover individual items of electrical equipment other than their selection for use. Note the following identifies the horizontal functions that have been assigned to TC 64: This committee has published 182 standards.

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.
