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

active, Most Current
 Organization: ISO Publication Date: 1 April 2017 Status: active Page Count: 14 ICS Code (Plastics in general): 83.080.01 ICS Code (Ignitability and burning behaviour of materials and products): 13.220.40
##### scope:

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).
