FOREWORD
This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the Radiocommunication Sectional Committee had been approved by the Electronics and Telecommunication DivisionCouncil.
There is no ISO/IEC standard on this subject.
The technical Committee responsible for the formulation of this standard has reviewed the provisions of thefollowing IEC Publication and has decided that it may be used in conjunction with this standard till IndianStandard on this subject is published:
IEC 60169-2 (1965) 'Radio frequency connectors: Part 2 Coaxial unmatched connectors [includingAmendment No. I (1982)]'.
The composition of the Committee responsible for formulation of this standard is given in Annex B.
For the purpose of deciding whether a particular requirement of this standard is complied with, the final value,observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance withIS 2 : 1960 'Rules for rounding off numerical values (revised)'. The number ofsignificant places retained in therounded off value should be the same as that of the specified value in this standard.
