Portable fire extinguishers - Part 11: Performance, requirements, test method and marking for EN 3-7 extinguishers suitable to be used on lithium-ion battery fires

Scope

This document describes performance requirements for portable fire extinguishers in addition to the requirements of EN 3-7+A1:2007, to demonstrate their suitability for extinguishing fires in rechargeable and non-rechargeable batteries based on lithium ion chemistry with a limited capacity, as used in:
- 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 abovementioned applications. Suitability for extinguishing larger fire risks, such as vehicle batteries and battery sets of stationary energy storage systems, cannot be validated with this document.
