GB/T 32577-2016 Measurement procedures of magnetic field levels generated by electronic and electrical apparatus in the railway environment with respect to human exposure
Abstract
This standard specifies the measurement and simulation/calculation methods for magnetic field strength in rail transit environments where humans (including those with pacemakers) are present, but does not consider the impact of the following factors: -- High-power transients (such as short circuits, grounding faults, and transformer overvoltages); -- Personal electronic devices of passengers and staff (such as mobile phones, laptops, and wireless communication systems); -- Dedicated transmitters with frequencies higher than 20 kHz. This standard applies to equipment, systems, and ground devices in rail transit environments with magnetic field frequencies ranging from 0 GHz to 300 GHz. Due to the natural characteristics of magnetic field sources in rail transit environments, only the values of magnetic fields in the range of 0 kHz to 20 kHz are considered and measured.
