Edition date: 2026-10-14
In Force
Available languages: German, French, English
Summary: This document specifies performance requirements for portable fire extinguishers in addition to the requirements of EN 3 7, to demonstrate their suitability for extinguishing fires in rechargeable batteries based on lithium-ion chemistry with a maximum capacity of 600 Wh, as used for example: — portable electronic equipment (smartphones, laptops); — power tools and domestic appliances; — portable medical equipment; — toys and radio-controlled objects; — drones; — bicycles. This document contains general requirements and procedures for extinguishing tests. The size of the extinguishing tests is comparable to the battery capacities in the above mentioned applications where the battery is accessible. This document doesn’t apply to larger fire risks, such as vehicle batteries, fork lift trucks, and battery sets of stationary energy storage systems.

Le présent document spécifie les exigences de performance applicables aux extincteurs d’incendie portatifs en complément des exigences de l’EN 3 7, afin de démontrer leur aptitude à éteindre des feux de batteries rechargeables basées sur la chimie du lithium-ion, d’une capacité maximale de 600 Wh, telles que celles utilisées dans, par exemple: — les équipements électroniques portables (smartphones, ordinateurs portables); — les outils électroportatifs et les appareils ménagers; — les équipements médicaux portatifs; — les jouets et les objets radiocommandés; — les drones; — les bicyclettes. Ce document contient des exigences générales et des procédures pour les essais d’extinction. La taille des essais d’extinction est comparable aux capacités des batteries dans les applications susmentionnées où la batterie est accessible. Le présent document ne s’applique pas aux risques d’incendie plus importants, tels que: batteries de véhicules, batteries de chariots élévateurs et batteries des systèmes fixes de stockage d’énergie.

Dieses Dokument legt zusätzlich zu den Anforderungen von EN 3 7 Leistungsanforderungen für tragbare Feuerlöscher fest, um deren Eignung zum Löschen von Bränden in wiederaufladbaren Batterien auf Basis von Lithium-Ionen-Chemie mit einem maximalen Energieinhalt von 600 Wh nachzuweisen, wie sie zum Beispiel angewendet werden in:  tragbaren elektronischen Geräten (Smartphones, Laptops);  Elektrowerkzeugen und Haushaltsgeräten;  tragbaren medizinischen Geräten;  Spielzeug und funkgesteuerten Objekten;  Drohnen;  Fahrrädern. Dieses Dokument enthält allgemeine Anforderungen und Verfahren für Löschprüfungen. Der Umfang der Löschprüfungen ist mit den Batteriekapazitäten in den vorstehend aufgeführten Anwendungen vergleichbar, bei denen die Batterie zugänglich ist. Dieses Dokument gilt nicht für größere Brandrisiken, wie Fahrzeugbatterien, Gabelstapler und Batteriesätze stationärer Energiespeichersysteme.
