ISO 8191-1~2:1988 Upholstered Furniture Ignitability Testing Machine

Parameter index:
4.1 simulate match flame；
4.1.1. 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)；
4.1.2. Hose: the length shall be (2.5-3mm) and the inner diameter shall be (7 ± 1mm) connected to the stainless steel combustion pipe；
4.1.3. Flow control system: including a flow meter, trim valve, on-off valve and pressure regulating valve；
4.1.4. When the flow is (45 ± 2) M1 / min, the nominal output pressure provided by the system is 2.8kpa；
4.1.5. Timing range: 0-999S, which can display and record the time of afterburning or smoldering, the time of fabric cracking, and the time of test piece extinguishing；
4.1.6. Test distance of igniter: 20-80 adjustable, with automatic movement and evacuation of ignition mechanism 7. Flow measurement range: 10 ~ 100m1 / min；

4.2 Smoldering Cigarettes
4.2.1 cigarette ignition source；
4.2.2 cigarettes are cylindrical cigarettes with filter tips or without filter tips and interface packages, and meet the following requirements:
Length: 60 ± 5mm;
Diameter: 8 ± 0.5mm;
Mass per unit length: (0.6 ± 0.1) g / 50mm;
4.2.3 cigarette burning time: (12 ± 3) min / 50mm；
4.2.4 in the same kind of cigarettes, every 10 cigarettes are a group, and one cigarette is randomly selected from them. The burning time of cigarettes is measured in the laboratory according to the following method: after the cigarette is pretreated, one cigarette is taken out, and marks are made at 5mm and 55mm from the ignition end of the cigarette. Insert the non ignition end of the cigarette into a thin steel needle horizontally, and the insertion length is not more than 11mm；

4.3 laboratory: 2.5m long, 2.2m wide and 2.5m high, including ventilation duct；
4.4 observation window: one large observation window of tempered glass, surrounded by SUS304 stainless steel；
4.5 gas flow adjustment: adjust the test gas flow to 45 ± 2ml / min；
4.6 timing: 0-99.99h/m/s arbitrary setting；
4.7 control system:
4.7.1 touch screen control system (test time, test times, delay time, etc.) can be set and recorded in the computer. It has the characteristics of high intelligence, guided menu operation, simple and intuitive, and makes the test results more accurate.
4.7.2 automatic ignition function (high voltage electronic fire).
4.7.3 PLC mode is adopted, and all high-quality devices are used to ensure the high-quality, high-speed operation and progressiveness of the system. The imported PLC + PID full-automatic control mode test process is the most advanced, safe, reliable and convenient control mode. Realize automatic detection control and complete the detection work automatically. The friendly display interface makes 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.
