Classes of fire-retardant treated wood products in interior and exterior end use applications - Reaction to fire performance
Abstract
This document describes test methods and methods for classification of wood and wood-based products for which a stage in the production process results in an improvement of the reaction-to-fire classification in accordance with EN 13501-1 for use in interior and exterior situations (use classes 1, 2, and 3 as defined in EN 335:2013). NOTE The classes of this document are not performance classes and do not give guidance for how long the reaction to fire classification of wood or wood-based product will last. This document applies to - wood and wood-based products (specific wood species, wood treated with preservatives and modified wood, for example thermally and chemically modified wood) that have been treated with fire-retardant chemical(s) applied either by a penetrating process or by a superficial process, such as with a film forming fire-retardant coating. - wood-based products that incorporate fire retardant chemical(s) as part of the production process. This document also covers fire-retardant wood and wood-based products that have a non-fire-retardant coating. Mechanical properties, aesthetic properties, dimensional stability properties, service life and biological durability of fire-retardant wood and wood-based products are not covered by this document. NOTE 2 This document is relevant for, but not limited to, products covered by these products standards: EN 13986, EN 14081-1, EN14374, EN 14915 and EN 16351. NOTE 3 EAD 350865-00-1106 covers fire retardant products (coating) applied in situ.
