Tests for fire detection systems intended for engine compartment according to SP Method 5320.
The test method described in this document is intended to test and rate the detection performance of fire detection systems installed in engine compartments. The test method also examines the durability of the system components.
To ensure early detection of fire and durability of detection systems, there is a need for fire detectors intended for engine compartments to be tested. Many of the challenges in this environment, are namely not specifically tested for in other standards for fire detection systems. These challenges are, for example, complex geometries cluttered with obstructions, high airflows, high temperatures and hot surfaces, dirt and dust, as well as vibrations, shocks and corrosion. SP Method 5320, considers these challenges, allowing for rapid performance evaluation under realistic and repeatable conditions.
The test method is divided over a number of different categories. Firstly, the complete system is test in a mock-up engine compartment as follows:
To secure the surviveability of the fire detection system and its components they are also subjected to component tests. These tests consider their durability to corrosion, ageing, temperature variations, vibrations, schock, EMC as well as ingress of dust and water. Before and after these tests, individual components are also subjected to the following test cases:
After testing, a test report is delivered with the results which may be the basis for product approval (P-mark) according to SPCR 197.
