FOREWORD
This Indian Standard ( Second Revision ) was adopted by the Bureau of Indian Standards, after the
draft finalized by the Winding Wires Sectional Committee had been approved by the Electrotechnical
Divisron Council.
This standard was first published in 1962. First revision of this standard was undertaken in 1981 to
bring it in line with the practice followed and experience gained through its implementation.
The second revision has been undertaken in order to update mainly the dimensions of drums.
This standard is intended to cover the technical provisions relating to drums of covered winding
wires and strips as supplied. It does not include the provisions of reeling and wrapping which shall
be in accordance with the product specification.
For the purpose of deciding whether a particular requirement of this standard is complied with, the

final value, observed or calcula ted, 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.
