IS/IEC 60371-3-9 : 1995
Solid Electrical Insulating Materials and Insulating Systems Sectional Committee, ETD 02
NATIONAL FOREWORD
This Indian Standard (Part 3/Sec 9) which is identical with IEC 60371-3-9 : 1995 ‘Insulating materials based
on mica — Part 3: Specifications for individual materials — Sheet 9: Moulding micanite’ 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.
This standard was first published as IS 9299 (Part 3/Sec 2) : 1982 ‘Insulating materials based on built-up
mica or treated mica paper: Part 3 Specifications for individual materials, Section 2 Moulding mica materials
for electrical purposes’. The committee has now decided to adopt the IEC Standard to harmonize it with the
latest developments taken place at international level. This standard is now being published in single
number based on IEC 60371 in various parts/sections. Other parts in this series are:
Part 1 Definitions and general requirements
Part 2 Methods of test
Part 3 Specifications for individual materials,
Section 1 Commutator separators and materials
Section 2 Mica paper
Section 3 Specification for rigid mica materials for heating equipment
Section 4 Polyester film-backed mica paper with a B-stage epoxy resin binder
Section 5 Glass-backed mica paper with an epoxy resin binder for post-impregnation (VPI)
Section 6 Glass-backed mica paper with a B-stage epoxy resin binder
Section 7 Polyester film mica paper with an epoxy resin binder for single conductor taping
Section 8 Mica paper tapes for flame-resistant security cables
This standard supersedes IS 9299 (Part 3/Sec 2) : 1982 and after the publication of this standard
IS 9299 (Part 3/Sec 2) shall be treated as withdrawn.
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.

Only the English language text of the International Standard has been retained while adopting it in this Indian
Standard, and as such the page numbers given here are not the same as in the IEC Standard.
For the purpose of deciding whether a particular requirement of this standard is complied with, the final
value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance
with IS 2 : 1960 ‘Rules for rounding off numerical values (revised)’ . The number of significant places retained
in the rounded off value should be the same as that of the specified value in this standard.
