See Chinese contents: GB/T 34574-2017 GB/T 34574-2017: Limits and measurements of electromagnetic emission for high-speed train
This standard specifies the limit requirements, measurement conditions, measurement methods, measurement techniques and evaluation methods of electromagnetic emissions from high-speed trains. This standard is applicable to the measurement of magnetic field emission in the frequency range of 0 kHz ~ 20 kHz (not including 0) inside high-speed trains and the external emission of high-speed trains in the frequency range of 9 kHz ~ 1 GHz. Electric locomotives, intercity and urban rail EMUs can be implemented with reference to this standard.
