Over deze norm
This International Standard specifies methods for determining the minimum concentration of oxygen, in admixture with nitrogen, that will support combustion of small vertical test specimens under specified test conditions. The results are defined as oxygen index values. Methods are provided for testing materials that are selfsupporting 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/m3 . The methods may also be applicable to some cellular materials having an apparent density of less than 100 kg/m3 . A method is provided for testing flexible sheet or film materials while supported vertically.
