BS EN 62431:2008

This standard BS EN 62431:2008 Reflectivity of electromagnetic wave absorbers in millimetre wave frequency. Measurement methods is classified in these ICS categories:

• 29.120.10 Conduits for electrical purposes
• 19.080 Electrical and electronic testing
• 17.120.01 Measurement of fluid flow in general
• 33.120.10 Coaxial cables. Waveguides
• 17.220.20 Measurement of electrical and magnetic quantities

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.
