IEC 60556:2006

Gyromagnetic materials intended for application at microwave frequencies - Measuring methods for properties

IEC 60556:2006 describes methods of measuring the properties used to specify polycrystalline microwave ferrites in accordance with IEC 60392 and for general use in ferrite technology. These measuring methods are intended for the investigation of materials, generally referred to as ferrites, for application at microwave frequencies. It includes editorial improvements as well as improvements to the figures.
This publication is to be read in conjunction with IEC 60392:1972.

Matériaux gyromagnétiques destinés à des applications hyperfréquences - Méthodes de mesure des propriétés

La CEI 60556:2006 décrit des méthodes de mesure des propriétés utilisées pour spécifier des ferrites polycristallins pour hyperfréquences conformément à la CEI 60392 et l'utilisation générale de la technologie des ferrites. Ces méthodes de mesure sont destinées à l'étude de matériaux, les ferrites, pour les applications hyperfréquences. Elle inclut des améliorations éditoriales et des améliorations des figures.
Cette publication doit être lue conjointement avec la CEI 60392:1972.
