ASTM D2863 Oxygen Index Test Apparatus Limiting Oxygen Index Tester
This instrument is used for the determination of polymer combustion volume percentage of oxygen in the process of need, polymer oxygen index value is in the material after ignition, keep 50 mm long or combustion time of 180 s when the required oxygen and nitrogen in the mixing flow, just maintain the minimum oxygen concentration sample combustion (also called oxygen index).
Main Technical Parameter:
|
Adopt imported oxygen sensor, oxygen concentration can be digital displayed without calculation.the accuracy is higher and more accurate, the range is 0-100% |
|
|
Digital resolution |
±0.1% |

Oxygen sensor aging tips |
|
|
Standard oxygen concentration input |
|
|
The diameter of the combustion tube can be set (two common specifications are available) |
|
|
Flow adjustment range |
0-20L/min (0-1200L/h) |
|
Quartz glass tube |
75cm (can be customized according to user requirements) |
|

40mm±2mm/s |
|
Overall dimensions |
650mm×400×830mm (can be customized according to user requirements) |
|
Pressure gauge accuracy level 2.5, resolution |
0.01MPa |
|
Test environment: ambient temperature |
room temperature ~ 50 ℃;relative humidity: ≤70%; |
|
Input pressure |
0.05-0.3MPa |
|
Working pressure |
nitrogen 0.15-0.20Mpa oxygen 0.15-0.20Mpa |
|
The sample holder can be used for soft and hard plastics, various building materials, textiles, fire doors, etc. |
|
|
Propane (butane) ignition system, the ignition nozzle is made of a metal tube, and the end has a nozzle with an inner diameter of Φ2±1mm, which can be bent freely. Can be inserted into the combustion tube to ignite the sample, flame length: 16±4mm, size 5mm-60mm can be adjusted freely, |
|
|
Gas: Nitrogen and oxygen for industrial use, purity>99%; (user-provided/regular gas station industrial oxygen purity is generally between 99.2%-99.3%). |
|
|
Power requirements |
AC220 (+10%) V, 50HZ |
|
Maximum power consumption: |
150W |
|
Self-supporting material sample clamp: can be fixed on the axis of the combustion cylinder and can clamp the sample vertically |
|
|
Non-self-supporting material sample holder: can fix the two vertical sides of the sample to the frame at the same time (optional/applied to soft and non-self-supporting materials such as textiles) |
|
Advantage:
the program will automatically adjust to the oxygen concentration balance and emit a beep sound prompt, eliminating the trouble of manually adjusting the oxygen concentration;
rate. The closed-loop control is adopted. The oxygen concentration drift program is automatically adjusted back to the target value during the test, avoiding the disadvantage that the traditional oxygen index meter cannot adjust the oxygen concentration during the test. Improve test accuracy.
Application:
It is suitable for the determination of the combustion properties of materials such as plastics,rubber, fibers, foams, films and textiles, that is, the concentration percentage of the lowest oxygen in which the polymer just maintains combustion.
Applicable standards:
