IEC 60086-2 Ed. 12.0 b:2011

IEC 60086-2:2011 is applicable to primary batteries based on standardized electrochemical systems. It specifies the physical dimensions; and the discharge test conditions and discharge performance requirements. Significant changes from the previous edition are the deletion of eight battery types from this standard, the addition of an air hole placement diagram and deletion of the resistive hearing aid tests for the P-system (zinc air) hearing aid batteries, standardization of a new form of alkaline (L-system) 9 volt battery (6LP3146), addition of a common designation reference as Annex D and general adjustment of application tests and their minimum average duration values to reflect changes in battery usage.
