ISO 25745-3:2015规定了估算自动扶梯和自动人行道能耗的通用工具，以及现有、现代化或新自动扶梯和自动人行道能耗性能分类的一致方法。 它考虑了自动扶梯和自动人行道生命周期运行部分的能源性能。它不包括辅助设备的能耗和分类，例如: a） 除梳状板照明、台阶间隙照明和交通灯外的照明（梳状板照明、台阶间隙照明和交通灯被认为是设备运行的必要条件，因此不被定义为辅助设备）； b） 冷暖和机房通风； c） 报警装置和应急电池供电设备等。； d） 环境条件； e） 通过电源插座消耗。 可能存在与自动扶梯或自动人行道无关且不包括的其他电气负载。 ISO 25745-3:2015考虑了所有电梯和高达8米的倾斜移动人行道，以及高达60米的水平移动人行道（约占全球安装机组的85%）。

ISO 25745-3:2015 specifies generic tools for estimating energy consumption of escalators and moving walks, and a consistent method for energy performance classification of existing, modernized, or new escalators and moving walks. It considers the energy performance 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 (comb 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 conditions; e) consumption through the power sockets. There can be other electrical loads not associated with the escalator or moving walk, and not included. ISO 25745-3:2015 considers all escalators and inclined moving walks up to a rise of 8 m and horizontal moving walks with a length up to 60 m (this represents about 85 % of worldwide installed units).
