This document specifies the general requirements for the oxygen index (OI) test which are further described in ISO 4589 2 and ISO 4589 3 as follows: ISO 4589 2 describes a method for determining the minimum volume fraction of oxygen in a mixture of oxygen and nitrogen introduced at 23 °C ± 2 °C that will just support combustion of a material under specified test conditions; ISO 4589 3 describes methods of carrying out the same determination over a range of temperatures typically between 25 °C and 150 °C (although temperatures up to 400 °C can be used).
