25、 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. 2) They have the form of recommendations for international use and they are accepted by t
26、he National Committees in that sense. 3) In order to promote international unification, the IEC expresses the wish that all National Committees should adopt the text of the IEC recommendation for their national rules in so far as national conditions will permit. Any divergence between the IEC recomm
27、endation and the corresponding national rules should, as far as possible, be clearly indicated in the latter. PREFACE This standard has been prepared by IEC Technical Committee No. 40: Capacitors and Resistors for Electronic Equipment. The text of this standard is based upon the following documents:
