适用范围：1 The special requirements of this section apply to temporary installations provided for:- works of new building construction;- works of repair, alteration, extension, or demolition of existing buildings;- public engineering works;- earthworks;- and similar works.The rules do not apply to installations covered by IEC 60621, or to other installations where equipment of a similar nature to that used in surface mining applications is involved.Parts of buildings which undergo structural alterations, such as extension, major repair or demolition, are considered to be like construction sites during the period of relevant works, to the extent that the work necessitates the provision of a temporary installation.For the administrative locations of construction sites (offices, cloakrooms, meeting rooms, canteens, restaurants, dormitories, toilets, etc.) the general rules of Parts 1 to 6 of IEC 60364 apply.NOTE - For special situations, more severe requirements apply, e.g. Section 706 for restrictive conductive locations5 In construction sites, fixed installations are limited to the assembly comprising the main controlgear and the principal protective devices (see 704-537).Installations on the load side are considered as movable installations except for parts which are designed according to Chapter 52: Wiring systems.
