They have the form of recommendations for internationa

23、l use and they are accepted by the National Committees in that sense. In order to promote international unification, the I E C expresses the wish that all National Committees should adopt the text of the I E C recommendation for their national rules in so far as national conditions will permit. Any

24、divergence between the I E C recommendation and the corresponding national rules should, as far as possible, be clearly indicated in the latter. The I E C has not laid down any procedure concerning marking as an indication of approval and has no responsibility when an item of equipment is declared t

27、 and Measuring Methods. The second edition resulted from the addition to the first edition, which was restricted to a connector with characteristic impedance of 50 Cl, of a connector of the same general design but with characteristic impedance of 75 Cl. The first draft for the 75 Cl version was disc

As a result of this meeting, a draft, Document 46D(Central Oce)30, was submitted to the National Committees for approval under the Six Months Rule in June 1975.
