13Oxygen/nitrogen mixed gas inlet: including stabilizing valve, flow regulating valve, gas filter, and mixing chamber.

14Sample clamp can be used for both soft and hard plasticsTextiles, fire doors, etc

15Propane (butane) ignition system, flame length 5mm-20mm adjustable freely

16Gas:Industrial nitrogen and oxygen, purity>99%; (User provided).

17Power requirements:AC220（+10% ）V、50HZ

18Maximum power consumption:50W

19Igniter: There is onebrass tubeMade with a nozzle with an inner diameter of Φ 2 ± 1mm at the tail end, which can be inserted into the combustion cylinder to ignite the sampleThe nozzle can bend freely; Flame length: 16 ± 4mm, flameAdjustable size,

20Porous mesh: Metal wire mesh with a diameter of 80mm and a thickness of 0.5mm; Stainless steel mesh partition: diameter 73mm, thickness 1.2mm, uniformly distributed with small holes of diameter 2mm on top

21Self supporting material sample clamp: can be fixed at the axis position of the combustion cylinder、And it can vertically clamp the sample

22Non self-supporting material specimen clamp: capable of fixing both vertical edges of the specimen to the frame simultaneously(Optional, suitable for soft materials such as textiles)

23Timer: Measurement time can reach 0~999min, accuracy 0.5S

24The temperature control part adopts electronic cooling and heating technology, and the temperature is controlled within23 ± 2 ℃, no compressor or heating tube is required for temperature rise and fall, reducing noise and instrument size (optional)

25Smoke exhaust system: ventilation device

26Film roll tool: A stainless steel bar with a gap at one end and a diameter of 2mm.

Chassis and Partial Structure:

1. Control box: processed and formed by CNC machine tools, electrostatic spraying, beautiful, rust proof and anti-corrosion. Separate control of control and experimental parts, including a separate ventilation device

2. Combustion cylinder:The size and height are500±50mm,Inner diameter ￠75mm-ф100mmInner diameter of outlet: 40mmThere is a 10mm contraction opening at the top.

3. Box size:Length 83cm * width 30cm * height 107cm, ventilation device length 44cm * width 28cm * height 100cm

4.Mixer: Using glass bead filling to evenly mix oxygen and nitrogen. (Bead diameter 4.5mm, filling height 95mm, one bag)

5Sample fixture: self-supporting fixture that can vertically clamp the sample; Standard non self-supporting style rackTwo sets of style clips meet different testing requirements; Style clip plug-in type, making it easier to place styles and style clips

6.Standard spare glass tube to prevent accidental damage and meet uninterrupted testing requirements; The diameter of the tail pipe hole of the long rod igniter is ￠ 2 ± 1mm,Igniter flame length (5-50) mm can be adjusted freely

One bottle of industrial grade oxygen/nitrogen is used as the gas source, but as these gases are high-risk transport goods, they cannot be used asOxygen index analyzerThe accessories can only be purchased at the user's local gas station. To ensure the purity of the gas, please purchase it at a local regular gas station）
