New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 100/Sec 3) which is identical with IEC TS 62351-100-3 : 2020 ‘Power systems management and associated information exchange - Data and communications security - Part 100-3: Conformance test cases for IEC 62351-3, the secure communication extension for profiles including TCP/IP’ issued by the International Electro technical Commission (IEC) was adopted by the Bureau of Indian Standards on recommendation of the Power System Control and Associated Communications Sectional Committee and approval of the Electronics and Information Technology Division Council.

The text of IEC Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions 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’.

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.
