Conclusions:
A formal classification is to be assessed in accordance with EN 13501-5, “Fire classification of
construction products and building elements – Part 5: Classification using data from external fire
exposure to roof tests”.
Remarks:
The test results relate to the behaviour of the test specimens of a product under the particular
conditions of the test; they are not intended to be the sole criterion for assessing the potential fire
hazard of the product in use.
