The formal decisions or agreements of the IEC on technical matters, prepared by technical committees on which all the National Committees having a special interest therein are represented, express, as nearly as possible, an international consensus of opinion on the subjects dealt with. They have

Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. International Standard IEC 835-3-1 1 has been prepared by sub-committee 12E: Radio
