IS 5825 : 2024/IEC 60172 : 2020 Test Procedure for the Determination of the Temperature Index of Enamelled and Tape Wrapped Winding Wires
NATIONAL FOREWORD
This Indian Standard (Third Revision) which is identical to IEC 60172 : 2020 'Test procedure for the determination of the temperature index of the enamelled and tape wrapped winding wires' issued by the International Electrotechnical Commission (IEC), was adopted by the Bureau of Indian Standards on the recommendation of the Winding Wire Sectional Committee and approval of the Electrotechnical Division Council.
This standard was first published in 1970 and subsequently revised in 1993 and 2018. This revision has been undertaken to align it with the latest version of IEC 60172 : 2020.
The text of the IEC standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appears 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.
