ASTM D 2863 ISO 4589-2 Oxygen Index Tester for Solid Materials
Laminated Foam Sheets and Films
ASTM D 2863 ISO 4589-2 Oxygen Index Tester Introduction:
The oxygen index is a method for determining the minimum oxygen
concentration required to maintain the combustion of the sample in
an oxygen-nitrogen mixed gas flow under specified test conditions,
such as room temperature. Depending on the ambient temperature
during combustion, it can be divided into room temperature oxygen
index method and high temperature oxygen index method. It is
generally believed that the higher the oxygen index, the better the
flame retardant performance of the material, and the lower the
oxygen index, the easier it is for the material to ignite.

Operation steps of the ASTM D 2863 ISO 4589-2 oxygen Index Tester:
1. Put the size of the sample to be tested and put it in the sample
bracket
2. Install the sample bracket in the test room;
3. Adjust the test room's oxygen concentration to 0.5%;
4. Live the sample and record the ignition time;
5. Increase oxygen concentration, observe the combustion, and
record the critical oxygen index.
Precautions for ASTM D 2863 ISO 4589-2 oxygen Index Tester:
1. The sample should be kept pure and not disturbed by humidity,
dust, and oil pollution.
2. During operation, we need to comply with relevant safety
regulations to prevent accidents such as fire;
3. During the test process, the oxygen concentration should be
strictly controlled to avoid the impact on the test results.
4. After operation, clean the test equipment for the next time.
