IS 16046 : Part 1 : 2018/IEC 62133-1 : 2017 Secondary Cells and Batteries Containing Alkaline or Other Non-Acid Electrolytes — Safety Requirements for Portable Sealed Secondary Cells and for Batteries Made from Them for Use in Portable Applications Part 1 Nickel Systems

ICS 29.220.30

ETD 11

NATIONAL FOREWORD

This Indian Standard (Part 1) (Second Revision) which is identical with IEC 62133-1 : 2017 ‘Secondary cells and batteries containing alkaline or other non-acid electrolytes - Safety requirements for portable sealed secondary cells, and for batteries made from them, for use in portable applications - Part 1: Nickel systems’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of the Secondary Cells and Batteries Sectional Committee and approval of the Electrotechnical Division Council.

This standard was originally published in 2012 and subsequently revised in 2015. First revision was based on IEC 62133 : 2012. The second revision of this standard has been undertaken to align it with the latest version of IEC 62133-1 : 2017 to make pace with the latest international practices.

The major changes in this revision are as follows:

a) Separation of lithium systems into a separate Part 2; and

b) Inclusion of button cell requirements.

This Indian Standard is published in two parts. Other part in the series is:

Part 2 Lithium systems

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.
