9、mas. * Voir adresse any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International
10、 Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 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
11、 represented, express, as nearly as possible, an international consensus of opinion on the subjects dealt with. They have the form of recommendations for international use published in the form of standards, technical reports or guides and they are accepted by the National Committees in that sense.
12、In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard sha
13、ll be clearly indicated in the latter. International Standard IEC 933-4 has been prepared by IEC technical committee 84: Equipment and systems in the field of audio, video and audiovisual engineering. The text of this standard is based on the following documents: DIS I Report on voting I Full inform
14、ation on the voting for the approval of this standard can be found in the report on voting indicated in the above table.
