12. Working pressure: Nitrogen0.05-0.15Mpa oxygen 0.05-0.15Mpa oxygen/nitrogen mixed gas inlet: including stabilizing valve, flow regulating valve, gas filter, and mixing chamber.

13. The sample holder can be used for soft and hard plastics, textiles, fire doors, etc

14. Propane (butane) ignition system, flame lengthAdjustable from 5mm to 60mm

15. Gas: Industrial nitrogen, oxygen, purity>99%； （Note: The gas source and connection head should be provided by the user themselves）.

Tips:Oxygen index testerDuring the experiment, it is necessary to use a minimum of98% of industrial grade oxygen/nitrogen is supplied in one bottle each as a gas source. As these gases are high-risk transportation goods, they cannot be provided as accessories for oxygen index testers and 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)

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

17. Maximum power consumption:50W

18. Igniter: made of a metal tube with an inner diameter at the endA nozzle with a diameter of 2 ± 1mm can be inserted into the combustion cylinder to ignite the sample,Flame length: 16 ± 4mm, adjustable size

19. Self supporting material sample clamp: can be fixed at the axis position of the combustion cylinder and can vertically clamp the sample

20. Non self-supporting material specimen clamp: capable of fixing both vertical edges of the specimen to the frame simultaneously(optional Suitable for materials such as textile films)

IIIChassis structure

1. Control box: processed and formed using CNC machine tools,The steel plate spray box adopts electrostatic spraying,Separate control of control and experimental parts .

2. Combustion cylinder: High temperature resistant high-quality quartz glass tube (inner diameter ￠ 75mm, length)480mm) Inner diameter of outlet: 40mm

3Sample fixture: self-supporting fixture that can vertically clamp the sample; (Optional non self-supporting style frame), two sets of style clips meet different testing requirements; Style clip plug-in type, making it easier to place styles and style clips

4The diameter of the pipe hole at the tail end of the long rod igniter is ￠ 2 ± 1mm, and the flame length of the igniter (5-50mm) can be adjusted arbitrarily
