Revised Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 2) (Second Revision) which is identical with IEC 60317-2 : 2012 ‘Specifications for particular types of winding wires - Part 2: Solderable polyurethane enamelled round copper wire, class 130, with a bonding layer’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on recommendation of the Winding Wires Sectional Committee and approval of the Electrotechnical Division Council.

This standard was originally published in 1996 and subsequently revised in 2012. First revision was identical with 60317-2 : 2000 ‘Specifications for particular types of winding wires - Part 2- Solderable polyurethane enamelled round copper wire, class 130, with a bonding layer’, issued by the International Electrotechnical Commission. The second revision of this standard has been undertaken to align it with the latest version of IEC 60317-2 : 2012 and to incorporate the latest technological upgradation and to align it with latest IEC standard.

The major changes in this revision are as follows:

a) addition of requirements for appearance, new subclause 3.3; and

b) addition of pin hole test requirements, Clause 23: Pin hole test. Keywords: copper winding wire

The text of 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’ 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.
