This method assesses the fire suppression performance of fire suppression systems under mock-up operational conditions. For this purpose, several different types of fires are ignited and stabilised inside an enclosure with typical engine compartment characteristics before the fire suppression system is activated. After the fire suppression system has been activated and completely discharged, the system is evaluated based on its ability to extinguish various fire sources.

In order to ensure the reproducibility of the test and facilitate its adoption in different laboratories, the method utilizes a standardised mock-up.

The fire suppression system is evaluated both as a complete system and in terms of components.

Durability tests are adapted for harsh vehicle conditions and are adjusted to suit both on-road applications as well as off-road applications.
