NATIONAL FOREWORD

This Indian Standard (Part 3/Sec 1) which is identical with IEC 60763-3-1: 2010 ‘Laminated pressboard for electrical purposes – Part 3: Specifications for individual materials – Sheet 1: Requirements for laminated pre compressed pressboard, types LB3.1A.1, and LB3.1A.2’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of the Solid Electrical Insulating Materials and Insulating Systems 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 terminology 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.
