IEC 60556:2006+A1:2016 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. This consolidated version consists of the second edition (2006) and its amendment 1 (2016). Therefore, no need to order amendment inaddition to this publication.
