Description

This European Standard describes the characteristics for fire-retardant treated wood products.

NOTE 1 It is based on maintaining performance undiminished throughout the desired service life in the anticipated conditions of use.

The European Standard prescribes the classification requirements for the durability of the reaction to fire performance of fire-retardant treated wood products to be used in interior and exterior end use conditions.

This European Standard applies to wood which has been treated during a production process with fire retardant products applied either by a penetration process or by a superficial process, such as with a film forming or intumescent fire retardant coating. It covers fire-retardant treated products that are coated with an ordinary paint.

Mechanical properties and biological durability of fire-retardant treated wood products are not covered by this European Standard.

NOTE 2 This standard can be used for other manufactured wood products.

This standard covers wood products. It doesn’t cover wood-based panels.

NOTE 3 Wood based panels for construction are described in EN 13986.
