10、ttees).The object of the IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields.To this end and in addition to other activities,the IEC publishes International Standards.Their preparation is entrusted to technical committees;a
11、ny IEC National Committee interested in the subject dealt with may participate in this preparatory work.International,governmental and non-governmental organizations liaising with the IEC also participate in this preparation.The IEC collaborates closely with the International Organization for Standa
12、rdization(ISO)in accordance with conditions determined by agreement between the two organizations.2)The formal decisions or agreements of the IEC on technical matters express,as nearly as possible,an international consensus of opinion on the relevant subjects since each technical committee has repre
13、sentation from all interested National Committees.3)The documents produced have the form of recommendations for international use and are published in the form of standards,technical specifications,technical reports or guides and they are accepted by the National Committees in that sense.4)In order
14、to promote international unification,IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards.Any divergence between the IEC Standard and the corresponding national or regional standard shall be clear
15、ly indicated in the latter.5)The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with one of its standards.6)Attention is drawn to the possibility that some of the elements of this International Standard may
16、 be the subject of patent rights.The IEC shall not be held responsible for identifying any or all such patent rights.This standard has been prepared by IEC Technical Committee 64:Electrical installations and protection against electric shock.60364-7-704 Ed.2/CDV IEC:20 xx 3 Contents 700.1 INTRODUCTION.4 704 Construction and demolition site installations.4 704.1 Scope.4 704.1.1 4 704.2 Normative references.4 704.3 Assessment of general characteristics.5 704.313 Supplies.5 704.4 Protection for saf
