According to ISO 9705 of building materials fire prevention performance standards, this fire test machine control platform provides independent gas analysis, including heat release rate and other related test 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 surface of the article use the same principle with the cone calorimeter and SBI testmethod thatis based on the oxygen consumption. The method is to simulate the corner of the fire scene as a standard testconditions, 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 ISO 9705, and 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 is the heat release rate and the flashover time.
The test room is built by the density of 700kg / m³-A1 class fireproof material.
The internal dimensions of the room 3.6M X 2.4M X 2.4M.
The gate size: 0.8M (W) X2.0M (H).
Sandbox burner with propane gas and equipped with emergency shut-off devices.
Automatic ignition system to automatically record experimental data.
Independently movabletimetto display units.
10kV spark ignition, a cease-fire with safety devices. Fire extinguishing drainage system design.
The full scale room corner tester is equipped withstaircasefor easy maintenance exhaust pipes.
