According to ISO9705 of building materials fire prevention performance standards, this fire test machine control platform provides independent gas analysis, including heat release rate and other related tests required for related instruments, such as paramagnetic oxygen sensor, CO2/CO measuring instrument, He-Ni laser smoke density measurement and control system, etc.
Full-scale room corner test methods for the surface of the article use the same principle as the cone calorimeter and SBI test methods that are based on oxygen consumption.
The method is to simulate the corner of the fire scene as a standard test condition, and installation of a test sample entirely according to actual use, the test results apply only to specific sample installation, it is one of the most reliable standard test methods.
In the corner fire test, in accordance with the requirements of ISO9705, the measured material mounted on the inner walls of the room (at the top is not installed).
Using propane burners as a radiation source, the measurement of heat release rate, temperature, heat release, flashover time, CO2 /CO, and other parameters, for which the most important are the heat release rate and the flashover time.
