Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmen

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance
21、are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted.

This International Standard providesa) a method to estimate energy consumption
27、 of escalators and moving walks on a daily and an annual basis for escalators and moving walks,b) a method for energy classification of new, existing, or modernized escalators and moving walks,c) guidelines for reducing energy consumption that can be used to support building and environmental and en
28、ergy classification systems.This International Standard is intended to be a reference for the following parties: building developers/owners to evaluate the energy consumption of escalators and moving walks; building owners and service companies when modernising installations including reduction of e
29、nergy consumption; the installers and maintenance providers of escalators and moving walks; consultants and architects involved in specification of escalators and moving walks; inspecting authorities and other third parties providing energy classification services.The total energy consumption over t
30、he entire life cycle of escalators and moving walks consists of the energy to manufacture, install, operate, and dispose of the lifts. However, for the purpose of this International Standard, only operating energy (running and standby) performance is considered.In the preparation of this Internation
31、al Standard, Technical Committee ISO/TC 178/ WG 10 has initiated extensive research, which included the measuring and modelling of over 300 typical escalator and moving walk installations. The results of this research have been used to provide the numerical values shown in Table 3 and Table A.3.This
32、 International Standard is suitable for national/regional jurisdictional energy performance purposes.

33、ing walks1 ScopeThis part of ISO 25745 specifiesa) generic tools for estimating energy consumption of escalators and moving walks, andb) a consistent method for energy performance classification of existing, modernized, or new escalators and moving walks.This part of ISO 25745 considers the energy p
34、erformance during the operational portion of the life cycle of escalators and moving walks. It does not cover energy consumption and classification of the ancillary equipment, such as the following:a) lighting with the exception of comb plate lighting, step gap lighting, and traffic light;NOTE 1 Com
35、b plate lighting, step gap lighting, and traffic light are considered essential for the operation of the equipment and are therefore not defined as ancillary equipment.b) cooling and heating and machine room ventilation;c) alarm devices and emergency battery supplies equipment, etc.;d) environmental
36、 conditions;e) consumption through the power sockets.NOTE 2 There can be other electrical loads not associated with the escalator or moving walk, which shall not be included.This part of ISO 25745 considers all escalators and inclined moving walks up to a rise of 8 m and horizontal moving walks with
37、 a length up to 60 m.NOTE This represents about 85 % of worldwide installed units.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
