IS/IEC 61462 : 2023 Composite Hollow Insulators - Pressurized and Unpressurized Insulators For Use in Electrical Equipment with a.c. Rated Voltage Greater than 1 000 V and d.c. Voltage Greater than 1 500 V - Definitions, Test Methods, Acceptance Criteria and Design Recommendations
NATIONAL FOREWORD
This Indian Standard (First Revision) which is identical to IEC 61462 : 2023 'Composite hollow insulators - Pressurized and unpressurized insulators for use in electrical equipment with AC rated voltage greater than 1 000 V AC and D.C. voltage greater than 1 500 V - Definitions, test methods, acceptance criteria and design recommendations' issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of the Electrical Insulators and Accessories Sectional Committee and approval of the Electrotechnical Division Council.
This standard was first published in 2007 identical to IEC 61462 : 2007. This revision has been undertaken to align it with the latest International Standard of IEC 61462 : 2023.
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.
