To prepare harmonized standards (HDs and ENs)

- concerning protection against electric shock arising from equipment, from installations and from systems without limit of voltage;

- for the design, erection and verification of all kinds of low-voltage electrical installations, except those installations covered by the following CENELEC Technical Committees : TC 9X, TC 44X;

- 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 objects of the standards shall be

- to lay down requirements for the safety aspects of the design, erection and verification of electrical installations and co-ordination of electrical equipment;

- to lay down safety requirements for protection against electric shock;

- to lay down safety requirements for protection against other hazards arising from the use of electricity and

- to facilitate European exchanges that may be hampered by differences in national regulations.

The standards will not cover individual items of electrical equipment other than their selection and erection in an installation.
