ICS 29.220.10; 39.040.10

ETD 10

(Superseding IS 11675 : 1986)

NATIONAL FOREWORD

This Indian Standard (Part 3) which is identical to IEC 60086-3 : 2021 'Primary batteries - Part 3: Watch 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 first published in 1986 as IS 11675 : 1986, which was an indigenous Indian Standard on 'Specification for button cells - Silver oxide'. Consequent upon the reviewing of IEC 60086-3 : 2021, this adoption has been taken up in IS 6303 series under dual numbering to align it with the latest IEC standard IEC 60086-3 : 2021, this Indian Standard supersedes IS 11675 : 1986.

This standard is published in various parts. Other parts in this series are:

Part 0 General

Part 4 Safety of lithium batteries

Part 5 Safety of batteries with aqueous electrolyte

The text of the 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' appears referring to this standard, they should be read as 'Indian Standard'; and

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.
