适用范围：This part of ISO 4589 specifies methods for deter-mining the minimum concentration of oxygen, in a mixture with nitrogen, that will support combustion of small vertical test specimens under specified test conditions over a range of temperatures typically be-tween 25 ℃ and 150 ℃. The results are defined as oxygen index values at the test temperature, which is typical of the practical temperature that a plastic ma-terial may experience in an overheated service situ-ation. Methods are provided for testing materials that are self-supporting at the test temperature in the form of vertical bars or sheet up to 10,5 mm thick. These methods are suitable for solid, laminated or cellular materials characterized by an apparent density greater than 100 kg/m
