BS EN ISO 4589-2: Plastics – Determination of burning behaviour by oxygen index – Part 2: Ambient-temperature test & ASTM D2863: Standard test method for measuring the minimum oxygen concentration to support candle-like combustion of plastics (oxygen index)
The Oxygen Index (OI) measures the minimum percentage of oxygen in a test atmosphere that is required to marginally support combustion. The OI is an economical and precise quality control test of combustible materials. Its ease of use together with high levels of precision has made this technique a primary characterising and quality control tool to the plastic and electric cable industries and it has been specified by several military and transport groups.
Our apparatus enables the oxygen index to be determined in accordance with ASTM D2863, ISO 4589 Part 2 or the UK Naval Engineering Standard NES 714.
