Testing and assessment of reaction to fire performance of construction products (including, but not limited to, floor coverings) is uniformly regulated within the European Union (EU) and the European Economic Area (EEA), whereby the testing of floor coverings is in accordance with EN ISO 9239-1 (Radiant Panel Test) and / or EN ISO 11925-2 (Single Flame Test), and the classification is to be carried out in accordance with EN 13501-1.
The burning behaviour of floor coverings is expressed in classes A to F, with subscript fl (fl stands for flooring), where classes A (A1 and A2) are "non-flammable", classes B and C are "low flammability", classes D and E "normally flammable" and class F is "easily flammable". In addition to the fire behaviour, an indication of the smoke development (smoke emission) is also made in the classification; the suffix "s1" means "low smoke emission", the suffix "s2" stands for "strong smoke emission". Thus, the former designation "hard-to-burn / low-smoke" (B1/Q1) in Austria, fire index 5.3 in Switzerland and B1 in Germany is now expressed by the European classification "Cfl-s1" or "Bfl-s1".
required fire classes for the individual types of buildings and areas of
application, there is no unique European regulation; here, the respective
national regulations still apply. However, it can be assumed that, at least for
most public areas, a Cfl-s1 classification is required, while for
private areas the fire classes Dfl and Efl are usually
sufficient. In that context, it should also be noted that construction products
with the fire classification F are generally prohibited or severely restricted
in some Member States.
