2.structure:

1. It is composed of a calcium silicate plate with a thickness (13±1) mm and a nominal density of 650 kg/m3 and a fireproof glass with a size (110±10) mmx (1100±100) mm, which is a quartz high temperature glass, installed in front of the box so that the progress of the entire specimen and the combustion can be observed through the observation window during the test; A metal protective layer is installed on the outside of the test chamber, and under the observation window, a door can be tightly closed, which allows the specimen platform to be moved in or out; The panels are made of high-quality stainless steel with a thickness of 1.2mm.

2. The test chamber is composed of a sliding platform, which can strictly ensure that the specimen fixture is in a fixed horizontal position, and the total air circulation area between the test chamber and the specimen fixture (0.23±0.03) m2 is evenly distributed on both sides of the long side of the specimen

3.Radiant heat source:

1. It is a fine-pore ceramic hot spoke plate mounted in a metal frame, the outer frame of the radiation plate is made of stainless steel (2.5±0.2) mm, and the radiation plate is made of porous refractory. The radiation area size is (300±10) mmx (450±10) mm, the radiation plate can withstand a high temperature of 900 °C, and the air-gas mixing system through a suitable device to ensure the stability and repeatability of the test, the radiation heating plate is installed above the specimen fixture, and its long side and horizontal angle are (30±1) °C

4.Smoke extraction system:

1. Composition: The combustion gas used for extraction is not directly connected to the box. When the radiant plate is closed and the sample exit is closed at the specified position of the simulated sample, the gas flow rate in the flue of the chamber is (2.5±0.2) M/S

2. Smoke exhaust capacity: The smoke exhaust capacity of the smoke extraction system is (39-85) m3/min at a temperature of 25 ° C

3. The measurement of the flow rate of the smoke exhaust channel and the installation position, the measurement of the flow rate is measured by a digital display anemometer. The accuracy is ±0.1m/s. Mounted on the cabinet flue, the measurement point is just above the lower edge of the cabinet flue (250±10) mm on the centerline

4. Anemometer: imported brand hot film anemometer, measuring range 0-10m/s, smoke exhaust speed (2.5±0.2) m/s
