Horizontal flame chamber used for horizontal test.		Test Type:
Will be fixed on the bracket sample, the small flame in the combustion box, the flame lit in the free end of the test specimen, for a specified on fire, the burner automatically extinguished, burning time, fire extinguishing time natural, residual flame, flame spread for a specified distance or burn mark distance used time and other experimental phenomena. (according to the standard requirements of free setting of the corresponding combustion time).		Test Method:
Flame height is 38mm (blue flame is 19mm).		Flame Requirements:

It is mainly composed of electric control box, combustion test box (equipped with combustion blowtorch, electromagnetic valve, high-pressure igniter, sample jig, gas pipe, gas source, internal and external flame regulation device, signal control line, etc.).	Main Components of Equipment
wewon flammability chamber made of stainless steel;	Electrical Control System:
（1） The burning time is controlled by the time controller. The working time can be set according to the needs. The units are S (seconds), M (minutes), and H (hours); if 00S01 is set to 0.01 seconds, 15S00 is 15 seconds, and 10M00 is 10 minutes. It can also be used to manually control the burn time.
（2）The power switch is the overall power switch of the control box.
（3）Flame regulation: Control the gas flow to adjust the flame size.
The main technical parameters of flammability chamber:	Flammability Chamber:
（1）Made of stainless steel plate, the dimensions are 385mm wide x 204mm deep x 360mm high;
（2）There are 10 venting holes with a diameter of 19mm at the bottom, and the four walls have a 13mm wide ventilation groove around the top;
（3）Test stand: It is made of two metal plates with corrosion resistance and corrosion, and the length is × width is 394mm × 102mm;
（4）The metal comb has a length of 110 mm and 7-8 smooth scallops per 25 mm;
（5）Compliance with sampling test size: The combustion test sample is 356 mm × 100 mm.

The instrument is mainly composed of a control box and a combustion box.			Technical Performance Of The Equipment
Stainless steel, SUS 304, mirror type.		1. Burning box:
The inner diameter of the burner is ￠9.5±0.5mm. It is equipped with a needle valve to adjust the gas flow rate and adjust the flame height. The flame height can be adjusted from 20mm to 100mm according to the standard and equipped with a flame height gauge (38mm). The instrument is equipped with an electronic igniter for automatic ignition.	Burner:	2. Combustion system:
2, combustion timer, continuous combustion timer.	Timer:	3. Timing system:
0~99.99/S/M/H can be set freely.	Timer setting:
Made of corrosion-resistant metal plate with ash box.		4. Test fixture:
The front part of the combustion box is an observation window made of heat-resistant tempered glass, which is convenient for observing the combustion changes during combustion.		5. Observation window:
Shows the temperature inside the combustion chamber.		6. The temperature
