Scope
This standard specifies the measurement and calculation methods for the shielding effectiveness of electromagnetic shielding rooms with side dimensions not less than 2.0 m. The test frequency range is 9 kHz to 18 GHz. If necessary, the frequency can be extended to 50 Hz and 100 GHz at both ends. If the shielding room is used for a full-wave anechoic chamber or a half-wave anechoic chamber, the shielding effectiveness test should be conducted before the installation of the wave-absorbing material.
