GB/T 24808-2022 Electromagnetic compatibility for lifts,escalators and moving walks—Immunity

Scope

1.1 This document specifies the performance criteria and test levels for the electromagnetic compatibility of elevators, escalators, and automatic walkways to be permanently installed in buildings, including the basic safety requirements related to their electromagnetic environment. These provisions represent the basic electromagnetic compatibility requirements.
This document addresses the electromagnetic compatibility conditions in residential, office, and industrial buildings.
1.2 This document is based on the commonly known hazards and dangerous situations related to the electromagnetic compatibility of elevators, escalators, and automatic walkways when they are designed by their manufacturing units and used under foreseeable conditions.
This document is based on the assumption that no port with a rated current exceeding 100 A is connected to the safety circuit.
This document is based on the assumption that the distance between mobile phones and radio transmitters used at the frequencies and power levels specified in Table 1 and the safety circuit does not exceed 200 mm.
1.3 The performance criteria and test levels for devices or combinations of devices in general functional circuits do not include scenarios with a very low probability of occurrence.
This document does not apply to other devices that have been proven to comply with relevant national standards for electromagnetic compatibility and are not related to the safety of elevators, escalators, and automatic walkways, such as lighting devices, communication devices, etc.
