16、e IEC collaborates closely with the International 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
17、 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 the form of recommendations for international use published in the form of standards, technical reports or guides and they are ac

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 th
19、e corresponding national or regional standard shall be clearly indicated in the latter. The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with one of its standards. International Standard IEC 72-3 has been
20、 prepared by sub-committee 28: Mounting dimensions and output series, of IEC technical committee 2: Rotating machinery.
