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.
