Scope
This standard stipulates the measurement and simulation/calculation methods for the magnetic field strength in the rail transit environment where the human body (including people with cardiac pacemakers) exists, but does not consider the influence of the following factors: --High power transients (such as short circuit, ground fault and transformer overshoot, etc.); --Personal electronic equipment for passengers and staff (such as mobile phones, laptop computers and wireless communication systems, etc.); --Special transmitters with frequencies higher than 20 kHz. This standard applies to equipment, systems and ground installations in the rail transit environment with a magnetic field frequency of 0 GHz to 300 GHz. Due to the natural characteristics of the magnetic field source in the rail transit environment, only the value of the magnetic field from 0 kHz to 20 kHz is considered and measured.
