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.
