    Abstract - (Show below) - (Hide below)

    Specifies the measuring equipment and techniques to be used in assessing the conducted electromagnetic interference (EMI) generated by stabilized power supplies and especially by switched-mode power supplies. Relates mainly to power supplies for which the source current required does not exceed 25 A. The techniques employed follow the general principles given in CISPR publications. Requirements for measurements of radiated interference have not been included in this standard.
