FOREWORD
This Indian Standard was adopted by the Bureau ofIndian Standards, after the draft finalized by the Radio
communication Sectional Committee had been approved by the Electronics and Telecommunication Division
Council.
There isno ISO/IEC standard on this subject.
The technical Committee responsible for the formulation ofthis standard has reviewed the provisions ofthe
following IEC Publication and has decided that it may be used in conjunction with this standard till Indian
Standard on this subject is published:
IEC 60169-2 (1965) 'Radio frequency connectors: Part 2 Coaxial unmatched connectors [including
AmendmentNo. I (1982)]'.
The composition ofthe Committee responsible for formulation ofthis standard is given in Annex B.
Forthe purpose ofdeciding whethera particularrequirementofthis standard iscompliedwith, the final value,
observed or calculated, expressing the result ofa test or analysis, shall be rounded off in accordance with
IS2 : 1960'Rulesforrounding offnumericalvalues (revised)'. Thenumber ofsignificantplaces retained inthe
rounded offvalue should be the same as that ofthe specifiedvalue inthis standard.
