LT-JJ32 mattress, sofa anti-ignition characteristics testing machine

 

Product description

This machine simulates the ignition source of match flame and evaluates the anti-ignition characteristics of upholstered furniture.

 

Conform to the standard

Conform to GB 17927.1-2-2011 evaluation of flammability of upholstered mattresses and sofas -- part 1 and smoldering cigarettes and part 2 imitation match flame - related requirements of the standard.

 

Technical parameters

1. Simulate match flame

A. Igniting source system: two sets of stainless-steel combustion tubes, one with an inner diameter of (8±0.1mm) and one with an inner diameter of (6.5±0.1mm) and a length of (200±5mm).

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

C. Flow control system: including a flowmeter, fine tuning valve, on/off valve and pressure regulating valve.

D. With a flow rate of (45±2) m1/min, the system provides a nominal output pressure of 2.8 kPa.

E. Timing range: 0-999s, respectively, can display and record the time of subsequent combustion or smoldering, fabric cracking time, test piece extinguishing time.

F. Test distance of igniter: 20-80 adjustable, with ignition mechanism automatic movement and evacuation.

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

2. Smoldering cigarettes

A. Cigarette ignition source.

B. Cigarettes are cylindrical cigarettes packed with filters or without filters and interfaces, and meet the following requirements: length: 60±5mm; Diameter: 8±0.5mm; Mass per unit length :(0.6±0.1) g/50mm.

C. Cigarette burnup time :(12±3) min/50mm.

D. Every 10 cigarettes of the same kind are taken as a group, one cigarette is randomly selected and the burnup time of the cigarette is measured in the laboratory according to the following method: after the pretreatment of the cigarette, one cigarette is taken out and marked on the cigarette 5mm and 55mm from the ignition end respectively. Insert the non-ignition end of the cigarette into a thin steel needle horizontally, the insertion length is not greater than 11mm.The ignition point is lit and the time it takes for the cigarette to burn between the two marks is recorded.

3. Laboratory: 2.5m in length, 2.2m in width and 2.5m in height, including ventilation ducts. Made of stainless steel.

4. Observation window: one big toughened glass observation window, surrounded by SUS304 stainless steel edge.

5. Gas flow regulation: adjust the test gas flow rate to 45±2mL/min.

6 timing: 0-99.99h /m/s arbitrary setting

7. Control system

1) Computer control system, test time, test times, ignition delay time and so on can be set and recorded in the computer. With high intelligence, guided menu operation, simple and intuitive characteristics, so that the test results are more accurate.

2) Automatic ignition function (for high voltage electronic fire).

3) PLC mode is adopted, all high-quality components are adopted, to ensure that the system is of high quality, high speed and advanced. The imported PLC+PID automatic control test process is the most advanced, the safest, the most reliable, the most convenient control mode. Realize automatic detection control, automatic completion of detection work, friendly display interface, make the detection work faster and more accurate. The upper computer adopts configuration software design, can automatically generate temperature control curve and report output. Data collection and printing test results.

4) Lenovo brand computer: screen size: 18.5 inches, CPU model: AMD Semen 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, optical drive type: DVD-ROM operating system: Windows XP, graphics card type: integrated graphics card.

5) One printer.

6) a set of software, lifetime free upgrade.
