LT-JJ32 Mattress and Sofa Anti Ignition Characteristics Testing Machine

Technical parameters:
1. Simulate match flames
a. Ignition source system: Two sets of stainless steel combustion tubes with an inner diameter of (8 ± 0.1mm), an inner diameter of (6.5 ± 0.1mm), and a length of (200 ± 5mm).
b. Hose: The length should be (2.5-3mm) and the inner diameter should be (7 ± 1mm) connected to a stainless steel combustion tube.
c. Flow control system: including a flow meter, fine adjustment valve, on/off valve, and pressure regulating valve.
d. The system provides a nominal output pressure of 2.8 kPa for a flow rate of (45 ± 2) m1/min.
e. Timing range: 0-999S, can display and record the time of continuous or smoldering, fabric cracking time, and specimen extinguishing time respectively.
f. The test distance of the igniter is adjustable from 20 to 80, with automatic movement and evacuation of the ignition mechanism.
g. Flow measurement range: 10-100ml/min.
2. Smoky cigarettes
a. Cigarette ignition source.
b. Cigarettes are cylindrical cigarettes with or without filters and interface packaging, and meet the following requirements:
Length: 60 ± 5mm; Diameter: 8 ± 0.5mm; Mass per unit length: (0.6 ± 0.1) g/50mm.
c. Cigarette burning time: (12 ± 3) minutes/50mm.
d. In the same type of cigarette, every 10 cigarettes form a group, and one cigarette is randomly selected. The burning time of the cigarette is measured in the laboratory according to the following method: after the cigarette is pre treated according to 7. a, one cigarette is taken out and marked 5mm and 55mm away from the ignition end of the cigarette, respectively.
Insert the non ignition end of the cigarette horizontally into a thin steel needle, with an insertion length not exceeding 11mm. Ignite the ignition end according to the provisions of 8.2, and record the time it takes for the cigarette to burn between two markings.
3. Laboratory: 2.5 meters long, 2.2 meters wide, 2.5 meters high, including ventilation ducts. Made of stainless steel.
4. Observation window: One tempered glass observation window with SUS304 stainless steel edging around it.
5. Gas flow regulation: Adjust the test gas flow rate to 45 ± 2mL/min.
6. Timing: 0-99.99H/m/s can be set arbitrarily
7. Control system:
1) The computer control system can set and record the testing time, number of tests, and ignition delay time in the computer. Featuring high intelligence, guided menu operation, and simple and intuitive features, the experimental results are more accurate.
2) Automatic ignition function (for high-voltage electronic ignition).
3) PLC mode is adopted, and all high-quality devices are used to ensure the system is of high quality, high-speed operation and progressiveness. Adopting imported PLC+PID
The fully automatic control method testing process is currently the most advanced, safe, reliable, and convenient control method. Implement automatic inspection
Measurement control, automatic completion of detection work, friendly display interface, making detection work faster and more accurate. The upper computer is designed using configuration software,
Automatically generate temperature control curves and report outputs Data collection and printing of test results.
