Technical parameters
Components A combustion box, a control box, a gas supply system, and a sample holder
Control box It consists of box, pressure regulating valve and function pressure gauge, flow meter, timer,  switch
Burning test box The material (355×305) mm SUS304 stainless steel; the is bottom of the box is and the height is 760mm. The with a high temperature resistant glass door test box is additionally provided with a bayonet for observing the burning phenomenon.
Baffle & holes There is a baffle box, and 16 vent holes with a diameter of at 25mm below the top plate of the 12.5mm are evenly plate. There are 8 vent holes with distributed on the top diameter φ12.5mm on each side of the box, and the bottom of the hole is φ25mm from the bottom of the box.
Sample holder The sample holder SUS304 stainless steel clamp suspended is an inverted “U” type material in the center of the box. It mm, and the long axis of the sample after clamping. Located in the vertical direction. When can hold the sample of size (70×210) clamping the specimen, it should length of the specimen at a distance of 10 mm from be clamped along the entire the edge
The exposed surface is (50×210) mm. The to the top of the tank and can be outside the specimen clamp should be connected holder to observe the two cabinet. Rotate the specimen sides of the specimen.
Test flame The test flame is φ10mm, which is located at the center of the bottom edge of the sample. The top of the lamp is 19mm away from provided by Bunsen burner. The inner diameter of the lamp is the, and the air supply of the burner is adjusted. To produce a flame of (40 ± 2) mm high. The Bunsen bottom edge of the sample. The ignition time of the sample is 12s burner is made of copper.
Gas source Natural gas or propane can usually be used, and the input pressure should be (17.2±1.8) kPa.
Ignition mode High-voltage electronic automatic ignition system is adopted.
Timer Flame time, afterburning time, burning time can be arbitrarily set from 0 to 99.99s, the accuracy is 1s / h, the resolution is 0.01s.
