IEC 62431:2008(E) specifies the measurement methods for the reflectivity of electromagnetic wave absorbers (EMA) for the normal incident, oblique incident and each polarized wave in the millimetre-wave range. In addition, these methods are also equally effective for the reflectivity measurement of other materials: measurement frequency range: 30 GHz to 300 GHz; reflectivity: 0 dB to -50 dB; incident angle: 0° to 80°. It replaces and cancels IEC/PAS 62431 with corrections of obvious errors.
