ČSN EN ISO 25745-3 This part of ISO 25745 specifies a) generic tools for estimating energy consumption of escalators and moving walks, and b) a consistent method for energy performance classification of existing, modernized, or new escalators and moving walks. This part of ISO 25745 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; NOTE 1: 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. 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 a length up to 60 m. NOTE: This represents about 85 % of worldwide installed unit
