International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for

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. In order to promot
19、e 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 shall be clearly indi
