LT – JJ32 Anti-ignition characteristic tester for mattress and sofa

Technical parameters

A. Ignition source system: two sets of stainless steel combustion tube, one inner diameter (8±0.1mm) inner diameter (6.5±0.1mm) length (200±5mm).

B. Hose: length (2.5 ~ 3mm) inner diameter (7±1mm) shall be connected to the stainless steel combustion tube.

C. Flow control system: includes a flow meter, trimming valve, switching valve and pressure regulating valve.

D. The flow is required to be (45±2) m1/min, and the nominal output pressure provided by the system is 2.8kpa.

E. Timing range: 0-999s. It can display and record the time of continuous or smouldering, fabric cracking time and specimen extinguishing time respectively.

F. Test distances for igniters: 20-80 adjustable, with ignition mechanism for automatic movement and evacuation.

G. Flow measurement range: 10 ~ 100m1/min.

A. cigarette lighting.

B. cigarettes are cylindrical cigarettes with filter or without filter 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 burn up time 12±3) min/50mm.

D. In the same kind of cigarette, every 10 sticks are a group, from which one is randomly selected, and the burning time of cigarettes is measured in the laboratory according to the following method: after cigarette pretreatment, take out 1 stick, and mark it at 5mm and 55mm away from the ignition end. Insert the non-ignition end of the cigarette horizontally into a thin steel needle, the insertion length shall not be greater than 11mm. Light the ignition end and test the time spent burning the cigarette between the two markers.

1) computer control system, test time, test times, delay time, etc. can be set and recorded in the computer. With high intelligence, guided menu operation, simple and intuitive characteristics, make the test results more accurate.

2) automatic ignition function (high voltage electronic fire).

3) adopt PLC method, all use high quality devices, ensure the system high quality, high speed operation, advanced. Imported PLC+PID automatic control test process, is the most advanced, the most safe, the most reliable, the most convenient way of control. Automatic detection control, automatic detection, friendly display interface, so that the detection work faster and more accurate. The upper computer is designed with configuration software, which can automatically generate temperature control curve and report output, collect data and print test results.

4) lenovo-branded computer: screen size: 18.5 inches, CPU model: AMD flash X2 190, CPU frequency: 2500MHz, memory capacity: 2GB DDR3, hard disk capacity: 250GB 7200rpm, SATA2 graphics chip: high-performance integrated graphics card Shared memory capacity, cd-rom type: dvd-rom operating system: WINDOWS XP, graphics card type: integrated graphics card.

5) one printer.

6) one set of software, free upgrade for life.
