ISO 3941:2026 Classification of fires
This document classifies, into categories, the different kinds of fires each defined by the nature of the fuel. Such a classification is particularly useful in the context of equipment for fire protection and firefighting.
This third edition cancels and replaces the second edition (ISO 3941:2007), which has been technically revised.
The main changes are as follows:
— addition of a classification for lithium-ion battery fires;
— addition of Clause 4 which provides information on the hazards related to the fire classes.
