Product details
1、 Scope of use
The touch screen controlled building material flammability testing furnace adopts a stainless steel box body, which is an upgraded product with touch screen control, controllable automatic lifting of samples, and adjustable back and forth function of the built-in lamp. It is a high configuration building material combustion level testing instrument produced strictly in accordance with the national standard GB8626-2007. (The red part represents the parameters that are now mandatory for third-party testing units to accept)
The flammability test furnace for building materials is used to directly impact vertically placed samples with a small flame in a normal combustion environment to determine the flammability of building products. The flammability test furnace for building materials utilizes the Kleinbrenner principle from Germany to measure the combustion performance of B-grade building materials under direct impact of a small flame in the vertical direction (i.e. used for determining the combustion performance/flame retardant level of building materials at B-grade).
2、 Product functional features
1. The operation design conforms to ergonomics, and all experiments are completed through touch screen operation, with a high degree of automation. It can store previous test results and access previous test data;
2. Servo motor driven style rack with controllable automatic lifting and lowering;
3. The built-in lamp can be adjusted back and forth;
4.1.5mm stainless steel plate box body;
5.2 Tempered heat-resistant glass door double angle observation test, double (with lock) convenient and practical
6. High voltage automatic ignition, durable combustion;
7. The ignition source can automatically tilt at 45 degrees;
8. The flame height is adjusted through a precision control valve;
9. The sample holder can move up and down, as well as forward and backward;
10. Equipped with two types of sample clamps.
11. Flame measurement ruler;
12. High degree of automation, precise experimental data, and easy operation;
13. Box size: Width 835 x Depth 400 x Height 815mm
14. Material: 1.5mm stainless steel
15. The bottom of the box is a flat natural ventilation opening, which is composed of 5cm * 5cm square ventilation openings (a true 1.5mm thick steel plate ventilation opening, 50mm high) to maintain smooth airflow
16. Exquisite workmanship, truly solder free process
17. Touch screen display:
a. Size: 7-inch effective display size, length 15.5cm, width 8.6cm;
b. Resolution: 800 * 480
c. Communication interface RS232, 3.3V CMOS or TTL, serial port mode
d. Storage capacity: 1G
e. Using pure hardware FPGA driver for display, with "zero" startup time, it can run immediately upon power on
f. Adopting M3+FPGA architecture, M3 is responsible for instruction parsing, FPGA focuses on TFT display, leading in speed and reliability compared to similar solutions
g. The main controller adopts low-energy processors and automatically enters energy-saving mode
3、 Main technical parameters

2. Relative humidity: ≤ 85%;
3. Power supply voltage and power: 220V 50HZ 100W;
4. Gas source: Commercial propane with a purity of not less than 95%, which can also be replaced by liquefied petroleum gas in ordinary tests (users need to provide their own gas source for transportation safety);
5. Apply flame time of 15 seconds to the pattern of the Bunsei lamp
6. Single chip microcontroller control, digital display.
7. The burner aperture is Φ 0.17mm, the flame length of the burner is 20mm ± 2mm, and the burner can be tilted 45 °.
8. Apply a flame (1s-99s s) ± 0.5s to the sample, which can be adjusted arbitrarily with an accuracy of ± 0.2s.
9. Combustible gas source: Propane with a purity of over 95%.
Applicable standards:ISO11925-2:2002 E "Test Method for Flammability of Building Materials"
Design standards:GB/T8626-2007 "Test Method for Flammability of Building Materials"
In addition, GB8626-2007 4.10 requires that the wind speed device be optional. Recently, third-party testing units have mostly made requirements for acceptance, but the wind speed device was not purchased in the early stage and can be added later
