This Indian Standard (Part 13) (First Revision) which is identical with IEC 61400-13 : 2015 ‘Wind turbines generator systems - Part 13: Measurement of mechanical loads’ 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.

This standard was originally published in 2016 which was identical with IEC/TS 61400-13 : 2001. The first revision of this standard has been undertaken to align it with the latest version of IEC 61400-13 : 2015 to make pace with the latest developments that have taken place at International level.
