IEC 60086-5:2016

Primary batteries - Part 5: Safety of batteries with aqueous electrolyte

IEC 60086-5:2016 specifies tests and requirements for primary batteries with aqueous electrolyte to ensure their safe operation under intended use and reasonably foreseeable misuse. This fourth edition cancels and replaces the third edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- The definition of explosion was changed to suitable sentence in order to harmonize in IEC 60086 series;
- To prevent removal of hydrogen gas, we revised it to the suitable sentence;
- To prevent misuse, the battery compartments with parallel connections were revised to the suitable sentence;
- To clarify the method to determine the insulation resistance. Keywords: tests and requirements for primary batteries

Piles électriques - Partie 5: Sécurité des piles à électrolyte aqueux

L'IEC 60086-5:2016 spécifie des essais et des exigences pour les piles à électrolyte aqueux pour assurer leur fonctionnement sûr dans des conditions d'utilisation prévue et de mauvais usage raisonnablement prévisible. Cette quatrième édition annule et remplace la troisième édition parue en 2011. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- La définition du terme explosion a été modifiée pour l'harmoniser avec les autres définitions de la série IEC 60086;
- Empêcher l'élimination de l'hydrogène, la phrase a été révisée;
- Empêcher les mauvais usages, la phrase sur les compartiments avec des piles connectées en parallèle a été révisée;
- La méthode de détermination de la résistance d'isolement a été clarifiée. Mots clés: des essais et des exigences pour les piles
