    Abstract - (Show below) - (Hide below)

    Specifies radio interference measuring apparatus for the frequency range 0.009 MHz to 1000 MHz. Based on CISPR Publication 16 and intended for use as a specific reference for the legal implementation of regulations on the permissible limits of radio interference. Methods of use of the apparatus are given in appendices.
