International Standards and Conformity Assessment for all electrical, electronic and related technologies


Electrical installations and protection against electric shock


CLC/TC 64 Scope


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 and verification of all kind of electrical installations at supply voltage up to 1 kV a.c or 1,5 kV d.c., except those installations covered by the following IEC committees: TC 9X, TC 18X, TC 44X, TC 97, TC 99X,

- in co-ordination with TC 99X, concerning requirements additional to those of TC 99X 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,

- 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.
