NATIONAL FOREWORD

This Indian Standard (Part 0/Sec 1) (Second Revision) which is identical with IEC 60317-0-1 : 2013 ‘Specifications for particular types of winding wires — Part 0-1: General requirements — Enamelled round copper wire’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of the Winding Wires Sectional Committee and approval of the Electrotechnical Division Council.

This standard was originally published in 1993 and subsequently revised in 2012 identical with

IEC 60317-0-1 : 2008. The second revision of this standard has been undertaken to align it with the latest version of IEC 60317-0-1 : 2013.

The second revision of this standard has been undertaken to incorporate the latest technological upgradation and to align it with latest IEC Standard. The major changes in this revision are as follows:

- revision to the definition of nominal conductor dimension;

- new sub-clause containing general notes on winding wire, formerly a part of the scope;

- revision to elongation requirements in Table 4;

- revision to 13, breakdown voltage, to include new requirements for intermediate wire diameters;

- revision to continuity of insulation requirements in Table 13;

- revision to the introduction of Annex A;

- revision to B.2 of Annex B; and

- revision to Table C.1 of Annex C. Keywords: Requirements of enamelled round copper winding wires

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.
