ČSN EN 14135

(73 0889) This document is applicable to all coverings, including but not limited to renderings, boards with and without air gaps and installed with various support systems. 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 (specified in EN 13501-1). The fire protection ability is influenced 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.
