This document specifies a method for determining the ability of a covering to protect underlying materials against damage during a specified fire exposure.

The document is not used for the evaluation of fire resistance classifications (e.g. EI, EW, E,…) or reaction to fire classifications (according to EN 13501‑1).

The fire protection ability is nullified by the presence of combustible materials in the cavity behind the covering. The applicability of the results is limited according to the quantity and position of such combustible materials within that cavity.

NOTE          The amount of combustible materials permissible in the cavity is generally laid down in national regulations.
