FOREWORD

This Kenya Standard has been prepared by the Extra-Low Voltage Equipment Technical Committee under
the guidance of the Electrical Industry Standards Committee and is in accordance with the procedures of the
Bureau.

This is the first revision of KS 184 and in this revision the committee has retained the structure of IEC 60086
by covering the standard in 5 parts in separate documents, this part being Part 3, as follows:

KS04-184: Kenya Standard Specification for Primary Batteries.
Part 1: General
Part 2: Physical and electrical specifications
Part 3: Watch batteries
Part 4: Safety of lithium batteries
Part 5: Safety of batteries with aqueous electrolyte

This Part 3 has been aligned with IEC 60086-3:2011. Where any text differs from the IEC text, this is
indicated by a vertical line in the right hand margin.

Acknowledgement is hereby made for the use of IEC 60086-3:2011 in this standard.

For the purpose of this Kenya Standard, the source text should be/has been modified as follows:

(a) The words “this Kenya Standard” should replace “this International Standard” whenever they appear.

(b) A full point (.) has been used in place of a comma (,) when referring to a decimal marker.

(c)References to international standards should be replaced by references to the following equivalent Kenya
Standards:

This second edition cancels and replaces the first edition (2004) and constitutes a technical revision.

The major technical changes with respect to the previous edition are the drawings, a review of the table of
electrochemical systems and a harmonization of the marking clause with the other standards of the IEC
60086 series. Moreover, the table of the leakage levels was extended by adding drawings with better
visualization.

INTRODUCTION

The technical content of this part of IEC 60086 provides specific requirements and information for primary
watch batteries. This part was prepared through joint work between IEC TC 35 and ISO TC 114 to benefit primary
battery users, watch designers and battery manufacturers by ensuring the best compatibility between
batteries and watches.
This part will remain under continual scrutiny to ensure that the publication is kept up to date with the
advances in both battery and watch technologies.

NOTE Safety information can be found in IEC 60086-4 and IEC 60086-5.
