NATIONAL FOREWORD

This Indian Standard (Part 4/Sec 5) (First Revision) which is identical to IEC 62153-4-5 : 2021 'Metallic communication cable test methods - Part 4-5: Electromagnetic compatibility (EMC) - Screening or coupling attenuation - Absorbing clamp method' issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendations of the Wires, Cables, Waveguides & Accessories Sectional Committee and approval of the Electronics and Information Technology Division Council.

This standard was first published in 2021 and was identical to IEC 62153-4-5 : 2006. This revision has been brought out to align it with the latest version of IEC 62153-4-5 : 2021.

This edition includes the following significant technical changes with respect to the previous edition:

a) Reorganisation of clauses and annexes;

b) Extension of frequency range to 2,4 GHz;

c) Application of a virtual balun respectively balunless test procedure with multiport VNA.

The text of IEC standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions and terminologies are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and

b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
