NATIONAL FOREWORD

This Indian Standard (Part 1) (Second Revision) which is identical with IEC 60254-1 : 2005 ‘Lead-acid traction batteries - Part 1: General requirements and methods of test’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on therecommendation of the Secondary Cells and Batteries Sectional Committee and approval of the Electrotechnical Division Council.

This standard was originally published in 1969 and subsequently revised as IS 5154 : 1980 ‘Specifications for lead-acid traction batteries (first revision)’ based on IEC 60254 : 1967. This revision of the standard has been undertaken to align the standard with the latest edition of IEC 60254-1 : 2005. This standard is published in two parts. Other part in this series is: Part 2 Dimensions of cells and terminals and marking of polarity on cells

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