标准摘要
[中文适用范围]： 本文件规定了氧指数 (OI) 测试的一般要求，在 ISO 4589-2 和 ISO 4589-3 中进一步描述如下： 在 23 °C ± 2 °C 下引入的氧气和氮气仅支持燃烧在指定测试条件下的材料；通常在 25 °C 至 150 °C 之间（尽管可以使用高达 400 °C 的温度）。 [外文原描述]： 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).
