scope:

NEN-EN 16755 describes the characteristics for fire-retardant treated wood products. 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. This standard covers wood products. It doesn't cover wood-based panels.
