Popis
IEC 62431:2008
IEC 62431:2008 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. This bilingual version published in 2011-11, corresponds to the English version published in 2008-07.
