NATIONAL FOREWORD
This Indian Standard (Part 3) which is identical to IEC 60667-3-1: 2020 'Vulcanized fiber for electrical purposes - Part 3: Specifications for individual materials - Sheet 1: Flat sheets' 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 Insulation Systems Sectional Committee and approval of the Electrotechnical Division Council.
This Standard (Part 3/Sec 1) gives requirements for vulcanized fibre flat sheets for electrical purposes.
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
