scope:

This International Standard specifies the test method to evaluate the reaction of wall and ceiling products to fire when installed at the surface of a small room and exposed directly to a specified ignition source. The test represents a fire scenario, which starts under well-ventilated conditions in a corner of a specified room with a single open doorway. Tests performed in accordance with the method specified in this International Standard provide data for the early stages of a fire from ignition up to flashover. The method does not evaluate the fire resistance of products. The method is not intended to evaluate floor coverings. This method is not suitable for sandwich panel building systems, pipe insulation and façades for which specific ISO standards are available.
