FOREWORDThe formal decisions or agreements of the I E C on technical matters, prepared 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.They have the form of recommendations for international 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 divergence
between the I E C recommendation and the corresponding national rules should, as far as possible, be clearly indicated
in the latter.4) 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 to comply with one of its recommendations.PREFACE
This standard has been prepared by Sub-Committee 46D, Connectors for Radio Frequency Cables, of I E C Technical
Committee No. 46, Cables, Wires and Waveguides for Telecommunication Equipment.It contains Part 4: 21 mm Rigid Precision Coaxial Line and Associated Hermaphroditic Precision Coaxial Connector,
Characteristic Impedances 50 0 (Type 9/21) and 75 0 (Type 6/21), of the complete standard on rigid precision coaxial lines
and their associated precision connectors, and it is intended to be used in conjunction with Part 1, General Requirements 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 0, of a connector of the same general design but with characteristic impedance of 75 0.
The first draft for the 75 S2 version was discussed at the meeting held in Bucharest in 1974. As a result of this meeting, a
draft, Document 46D(Central Office)30, was submitted to the National Committees for approval under the Six Months' Rule
in June 1975.The following countries voted explicitly in favour of publication:
Poland
Austria
Belgium Romania
Canada Spain
Sweden
Denmark
France Switzerland
Germany Turkey
United Kingdom
Israel
Italy United States of America.
Japan
At a last discussion at the meeting held in Stockholm in 1976, the proposal was approved to combine the 50 S2 and the 75 0
versions of the connector in a second edition of Publication 457-4.Other IEC publications quoted in this standard:
