CLC/TC 64/WG 23 - To be set up - Construction and demolition side installation - Restrictive conductive locations

IEC 60364-7-7-704:2017(E) lays down requirements which apply to installations for construction and demolition sites for use during the period of the construction or demolition work which are intended to be taken out of service upon completion of the works. Examples include the following: - construction work of new buildings; - repair, alteration, extension or demolition of existing buildings or parts of existing buildings; - engineering works; - earthworks; - work of similar nature. The requirements apply to fixed or moveable installations. This new edition includes the following significant technical changes with respect to the previous edition: - clarification of the scope; - clarification of compliance with standards; - clarification of devices for isolation.

The particular requirements of this part apply to fixed equipment in conducting locations where movement of persons is restricted by the location, and to supplies for portable equipment for use in such locations. A conducting location with restricted movement is comprised mainly of metallic or other conductive surrounding parts, within which it is likely that a person will come in contact through a substantial portion of his body with the metallic or other conductive surrounding parts and where the possibility of interrupting this contact is limited.

The special requirements of this part apply to temporary installations for construction and demolition sites during the period of the construction or demolition work, including for example the following: - construction work of new buildings; - repair, alteration, extension, demolition of existing buildings or parts of existing buildings; - engineering works; - earthworks; - work of similar nature.
