IEC 60086-3:2011 specifies dimensions, designation, methods of tests and requirements for primary batteries for watches. In several cases, a menu of test methods is given. When presenting battery electrical characteristics and/or performance data, the manufacturer specifies which test method was used. This third edition cancels and replaces the second 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. This publication is published as a double logo standard. The contents of the corrigendum of September 2011 have been included in this copy. This bilingual version (2014-01) corresponds to the monolingual English version, published in 2011-01. Keywords: requirements and information for primary watch batteries.
