ISO 4589-1:2017

Plastics — Determination of burning behaviour by oxygen index — Part 1: General requirements

ISO 4589-1:2017 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).
