Primary batteries - Part 4: Safety of lithium batteries
IEC 60086-4:2025 specifies tests and requirements for primary lithium batteries to ensure their safe operation under intended use and reasonably foreseeable misuse. This sixth edition cancels and replaces the fifth edition published in 2019. This edition includes the following significant technical changes with respect to the previous edition: - Added definitions for leakage and venting, in addition to the test criteria; - Revised overdischarge test; - Revised marking requirements; - Revised criteria for the child resistant packaging test; - Changed the purpose of Annex F from "informative" to "normative"; - Added a new Annex G with additional measures against misuse of batteries not intended for consumer replacement; - Integrated the contents of Interpretation Sheet 1 (IEC 60086-4:2019/ISH1:2020); - In Clause 3, terms were reordered according their functions: basic terms, electrochemical systems, battery shapes, battery sizes, electrical characteristics, specifications, safety aspects, failure modes; - In 6.4.4, the exemption for the shock acceleration for lithium primary batteries was reduced from 12 kg to 4,482 kg in order to reflect the fact that this is the threshold in IEC 62281, Test T-4, where the peak acceleration decreases below 150 gn.

Piles électriques - Partie 4: Sécurité des piles au lithium
L’IEC 60086-4:2025 spécifie les essais et les exigences pour les piles électriques au lithium afin d’assurer leur fonctionnement en toute sécurité dans les conditions d’utilisation prévue et en cas de mauvais usage raisonnablement prévisible. Cette sixième édition annule et remplace la cinquième édition parue en 2019. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente: - ajout de définitions pour les concepts de fuite et de dégazage, en complément des critères d’essai; - révision de l’essai de décharge excessive; - révision des exigences de marquage; - révision des critères relatifs à l’essai des emballages à l’épreuve des enfants; - modification de l’objet de l’Annexe F, passant de "informative" à "normative"; - ajout d’une Annexe G stipulant des mesures supplémentaires contre le mauvais usage des piles qui ne sont pas destinées à être remplacées par le consommateur; - intégration du contenu de la Feuille d’Interprétation 1 (IEC 60086-4:2019/ISH1:2020); - réordonnancement des termes énumérés à l’Article 3 selon leurs fonctions: termes de base, systèmes électrochimiques, formes de piles, tailles de piles, caractéristiques électriques, spécifications, - considérations relatives à la sécurité, modes de défaillance; - en 6.4.4, réduction de l’exemption d’accélération pour l’essai de chocs des piles au lithium, passant de 12 kg à 4,482 kg, afin de refléter le fait qu’il s’agit du seuil défini pour l’essai T‑4 de l’IEC 62281, dans lequel l’accélération maximale descend en dessous de 150 gn.
