Title Reflectivity of electromagnetic wave absorbers in millimetre wave frequency - Measurement methods
Project Number 21085
Abstract/Scope 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.

Normative reference (6) EN ISO/IEC 17025:2005

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
