MT 14 - TC 35/MT 14

IEC 60086-2:2021 is applicable to primary batteries which are based on standardised electrochemical systems.
It specifies
– the physical dimensions,
– the discharge test conditions and discharge performance requirements.
The contents of the corrigendum of June 2022 have been included in this copy.

IEC 60086-1:2021 is available as IEC 60086-1:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 60086-1:2021 is intended to standardize primary batteries with respect to dimensions, nomenclature, terminal configurations, markings, test methods, typical performance, safety and environmental aspects. This document on one side specifies requirements for primary cells and batteries. On the other side, this document also specifies procedures of how requirements for these batteries are to be standardised. As a classification tool for primary batteries, this document specifies system letters, electrodes, electrolytes, and nominal as well as maximum open circuit voltage of electrochemical systems. The object of this part of IEC 60086 is to benefit primary battery users, device designers and battery manufacturers by ensuring that batteries from different manufacturers are interchangeable according to standard form, fit and function. Furthermore, to ensure compliance with the above, this part specifies standard test methods for testing primary cells and batteries.

IEC 60086-2:2015 is applicable to primary batteries based on standardized electrochemical systems. It specifies the physical dimensions, the discharge test conditions and discharge performance requirements. This thirteenth edition cancels and replaces the twelfth edition (2011) and constitutes a technical revision. Significant changes from the previous edition are test changes to battery types R03, LR03, R6, LR6, PR70, PR41, PR48, 6F22, 6LR61, 6LP3146 4LR25-2, R14, LR14, R20, LR20, CR2025, and CR2032, adding the 5AR40 back into the standard, addition of common designations, addition of two new battery types FR14505 and FR10G445, deletion of battery types LR53, R40, 2EP3863, 6F100, and general editorial changes. Keywords: primary batteries, electrochemical systems

This twelfth edition cancels and replaces the eleventh edition (2011) and constitutes a technical revision. The major technical changes with respect to the previous edition are:
- the order of the Annexes was changed to the order in which they appearin the document and a caption was added to indicate where the Annex information first appears in the document;
- the humidity conditions for non P-system batteries in Table 3 was modified;
- the standard discharge voltage for the Y and W chemistries was determined to be at 3,5 V and 2,8 V respectively;
- details on capacity measurement were moved from Annex E to Subclause 5.1.
- the coin/button cell and battery definition was clarified in order to better address issues with the swallowing of coin cells. Keywords: fundamental requirements and information on primary cells and batteries

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.
