ÖNORM EN 14390

This European Standard specifies a test method to evaluate the reaction to fire performance of building products. A fire is simulated which under well-ventilated conditions starts in a corner of a small room with a single open doorway. The method is intended to evaluate the contribution of a surface product to fire growth in a room configuration, using a specified ignition source. It constitutes a reference test for this type of product within the European classification system for reaction to fire performance of construction products. The method is particularly suitable for construction products which cannot be tested in their end use application in a small or intermediate laboratory scale. The method can also be used to assess the effect of an insulating substrate on the product performance. A test performed in accordance with the method specified in this European Standard provides data for the early stages of a fire from ignition up to flashover. The method is not intended to evaluate floor coverings. It may not be suitable for some free-standing products because their integrity, when exposed to fire, could have a decisive influence on their behaviour. NOTE The term surface product as used in the title and scope of this European Standard specifically relates to internal surface linings, assemblies, pipes and pipe insulation products used in buildings.
