NATIONAL FOREWORD

This Indian Standard (Part 4) (Second Revision) which is identical with IEC 60086-4 : 2007 ‘Primary batteries - Part 4: Safety of lithium batteries’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of the Primary Cells and Batteries Sectional Committee and approval of the Electrotechnical Division Council.

This standard was originally published in 1971 and was revised in 1984 to align it with the practice followed at international level. Test to determine leakage of electrolyte, continuous discharge test for determination of life and code of practice for transport, storage, use and disposal of batteries were added in this revision. The committee has now decided to revise this standard in line with IEC Standards and adopt it in various parts. Parts 4 and 5 of this standard has been adopted under dual numbering system to align it with the latest version of IEC 60086 in various parts. Others parts in this series are:

Part 1 General

Part 2 Physical and electrical specifications

Part 3 Watch batteries (under consideration)

Part 5 Safety of batteries with aqueous electrolyte

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.
