(Superseding IS 13310 : 1992)

New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 8) which is identical with IEC 63093-8 : 2018 ‘Ferrite cores - Guidelines on dimensions and the limits of surface irregularities - Part 8: E-cores’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendations of the Magnetic Components, Ferrite Materials, Piezoelectric and Frequency Control Devices Sectional Committee and approval of the Electronics and Information Technology Division Council.

IS 13310 was Originally Published in 1992 and was largely based on IEC Doc: 51 (Sec) 294 ‘Dimensions of E-cores with rectangular cross-sections made of magnetic oxides intended for general applications, and associated parts’. This IEC document was later published as IEC 63093-8. The superseding of above mentioned Indian Standard has been undertaken to align it with the latest version of IEC 63093-8 : 2018 and on publication of this standard, IS 13310 : 1992 will be withdrawn.
