Soft Furniture Spring Soft Mattress and Sofa Anti-ignition Characteristic Testing Machine
Use
Use Simulated match flame fire source to evaluate the anti-ignition characteristics of soft furniture.
Standard
ISO8191-1~2:1988, EN597-1~2:1995
Technical Parameters
1, Simulated match flame
1.1. Ignition source system: stainless steel combustion tube, one inner diameter (8±0.1mm) inner diameter (6.5±0.1mm) length (200±5mm), two sets
1.2. Hose: the length should be (2.5 ~ 3mm) and the inner diameter should be (7 ± 1mm) connected to the stainless steel combustion tube
1.3. Flow Control System: Includes a flow meter, trim valve, on-off valve, and pressure regulator.
1.4. The flow rate is (45 ± 2) m1/min. The nominal output pressure provided by the system is 2.8kpa.
1.5. Timing range: 0-999S, can display and record the time of continuous burning or smoldering, fabric cracking time, test piece extinguishing time,
1.6. Test distance of igniter: 20-80 adjustable, with automatic movement and evacuation of ignition mechanism 7. Flow measurement range: 10~100m1/min
2, Smoldering cigarette
2.1 cigarette ignition source
2.2 Cigarettes are cylindrical cigarettes with a filter or with a filter and interface package removed, and meet the following requirements:
Length: 60 ± 5mm;
Diameter: 8±0.5mm;
Mass per unit length: (0.6 ± 0.1) g / 50 mm;
2.3 Cigarette burning time: (12 ± 3) min / 50mm.
2.4 In the same cigarette, each group of 10 is selected from one of them, and the burning time of the cigarette is measured in the laboratory according to the following method: after the cigarette is pretreated according to 7.1, one is taken out, and the cigarette is separated from the cigarette. The ignition end is marked with 5mm and 55mm at each end. Insert the non-ignition end of the cigarette horizontally into a fine steel needle with an insertion length of no more than 11 mm. The ignition end is ignited in accordance with 8.2 and the test records the time it takes for the cigarette to burn between the two marks.
3, Laboratory: 2.5 meters long, 2.2 meters wide, 2.5 meters high, with ventilation ducts. Made of stainless steel.
3.1 Observation window: one large observation window of tempered glass, surrounded by SUS304 stainless steel
3.2 Gas flow regulation: adjust the test gas flow rate to 45 ± 2mL / min.
3.3 Timing: 0-99.99H/m/s arbitrarily set
3.4 Control System:
3.4.1 Computer control system, (test time, number of tests, flame retarding time, etc. can be set and recorded in the computer. With high intelligence, guided menu operation, simple and intuitive features, the test results are more accurate.
3.4.2 Automatic ignition function (for high voltage electronic fire).
3.4.3 Adopt PLC mode, all adopt high-quality devices to ensure high-quality system and high-speed operation, and advanced. It adopts the imported PLC+PID automatic control mode test process, which is the most advanced, safest, most reliable and most convenient control method. Realize automatic detection and control, auto-complete detection, and friendly and friendly display interface, making inspection work faster and more accurate. The upper computer adopts configuration software design, which can automatically generate temperature control curve and report output. Data acquisition and print test results
3.4.4 Computer: One.
3.4.5 One printer
3.4.6 software set, free upgrade for life
