Tips: oxygen index tester test required not less than 98% of the industrial-grade oxygen / nitrogen bottle as a gas source, as the above gases for high-risk transport products, can not be used as oxygen index analyzer accessories, only the user local Gas station to buy. (In order to ensure the purity of gas, please purchase at the local regular gas station)

What is oxygen Index test?

Measuring the Minimum Oxygen Concentration to Support Candle-Like Combustion of Plastics (Oxygen Index) ASTM D2863. Scope: ASTM D2863 is a method to determine the minimum concentration of oxygen in an oxygen/nitrogen mixture that will support a flaming burn in a plastic specimen.
