IS 13730 : Part 16 : 1996/IEC 317-16 : 1990 Specification for Particular types of winding wires: Part 16 Polyester enamelled rectangular copper wire, Class 155

National Foreword

This Indian Standard which is identical to IEC 317-16 : 1990issued by the International Electrotechnical Commission was adoptedby the Bureau of Indian Standards on the recommendation of theWinding Wires Sectional Committee, ET 33 and approval of theElectrotechnical Division Council.

Presently requirements of enamelled round and enamelledrectangular winding wires are covered under IS 4800 (series) and IS3855 (series) respectively over the years, changes in technologyand developments, resulted in publishing of number of amendments tothese standards. Even though Indian Standards were following thedevelopments in IEC level, but for some specific properties namelyresistivity of copper; methods of test, etc, IEC standards were notadopted in totality. Keeping in view the present trend in theindustry it has been decided to align the Indian standards onwinding wires by adopting the IEC standards intotality.

The series of IEC standards on methods of tests (IEC 851 series)and particular types of winding wires (IEC 317 series) were decidedand adopt with deviation as follows:

IEC 851 (series) Methods of test for winding wires has alreadybeen adopted and published as IS 13778/IEC 851 (series) in 6 part.

The adoption of IEC 317 (series) on particular types of windingwires is being carried out in phased manner under the series IS13730/IEC 317.
