New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 23) which is identical with IEC 61400-23 : 2014 ‘Wind turbines — Part 23: Full-scale structural testing of rotor blades’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on recommendation of the Wind Turbines Sectional Committee and approval of the Electrotechnical 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’ appearreferring to this standard, they should be read as ‘IndianStandard’.

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.
