FOREWORD
I) The 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.
2) They have the form of recommendations for international use and they are accepted by the National Committees in that
sense.
3) 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 recommendations and the corresponding national rules should, as far as possible, be clearly
indicated in the latter.
PREFACE
This recommendation has been prepared by Sub-Committee 46D, Connectors for R.F. Cables, of I EC
Technical Committee No. 46, Cables, Wires and Waveguides for Telecommunication Equipment.
A first draft was discussed at the meeting held in The Hague in 1970. As a result of this meeting, a final
draft, document 46D(Central Office)2, was submitted to the National Committees for approval under the
Six Months' Rule in July 1971. Amendments, document 46D(Central Ofiîce)11, were submitted to the
National Committees for approval under the Two Months' Procedure in September 1972.

Non-operating
The performance of the assemblies shall remain within the electrical and mechanical
specifications when tested under normal operating conditions, after having been
exposed to the environmental conditions specified in I E C Publication 457-1, Rigid
Precision Coaxial Lines and their Associated Precision Connectors, Part 1: General
Requirements and Measuring Methods.
The following severities apply: Test A: — 55 °C; Test B: + 70 °C.
8. Dimensions
The inch dimensions are derived from the original millimetre dimensions.
The nominal inside diameter of the outer conductor shall be 7 mm (0.275 590 in).
Maximum deviations on the inner and outer diameters shall limit the uncertainty in
0.2 % or less, with a maximum deviation on the inside

diameter of the outer conductor of ± 0.005 mm (± 0.0002 in). The nominal outside
diameter of the centre conductor shall be 3.040 mm (0.119 685 in).
Dimensions shall also be checked after the tests according to I E C Publication 457-1,
Section Four, have been carried out.
For the critical dimensions of the mating faces, coupling attachment or coupling
means, refer to Figures 1, 2 and 3, pages 10, 11 and 12, respectively.
10.1 Centre contact force of mated hermaphroditic connectors
When two connectors are mated, the axial force exerted by the contact mechanism on
the centre conductor of a connector shall be max. 9.0 N and min. 4.0 N.
When a force of 18 N is applied for a least 12 h, the centre conductor of a connector
shall be displaced axially less th
