New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 1) which is identical with IEC 62660-1 : 2010 ‘Secondary lithium-ion cells for the propulsion of electric road vehicles - Part 1: Performance testing’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on recommendation of the Secondary Cells and Batteries Sectional Committee and approval of the Electrotechnical Division Council.

The text of IEC standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and 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.
