Tests for fire suppression systems intended for engine compartments according to SP Method 4912, UNECE R107, AIS 135
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 engine compartment characteristics. Fire suppression systems are then evaluated based on its ability to extinguish the various test fires.
SP Method 4912 tests fire suppression systems intended for engine compartments in a well-defined and objective way. Systems are subjected to realistic fire scenarios that can occur on and around a vehicle or machine, as a means to evaluate their performance. The system tests are based on the geometry, obstructions and air flow typically found in engine compartments. This allows for rapid performance evaluation under reproducible and repeatable conditions.
The fire suppression system may be subjected to the test scenarios listed below. In the end, a system will achieve a ranking based on the number of tests completed and the conditions, e.g. ventilation rates and/or level of openness of the testing rig, under which this was achieved.
The Level of Opennes of our testing rig can be modified to reflect the environment in which the fire suppression system shall be used. This will affect the final rating of the fire suppression system also, with an increasing score for an increasing level of openness. The highest possible openness level is achieved when tests are completed when no floor, ceiling, and walls are considered in the testing rig.
After testing, a test report is delivered with the results which may be the basis for product approval, for example according to SPCR 183 or SPCR 199 (P-mark).
