Classes of fire-retardant treated wood products in interior and exterior end use applications - Retained performance of fire-retardant treated wood products
Abstract
This document describes test methods and methods for the retained performance classification of wood products with a stage in the production process resulting 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 [3]). NOTE 1 The classes of this document are not performance classes and do not give guidance for how long the reaction to fire classification of wood product will last. This document applies to - wood 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. This document also covers fire-retardant wood products that have a non-fire-retardant coating. Mechanical properties, aesthetic properties, dimensional stability properties, service life and biological durability of fire-retardant wood products are not covered by this document. NOTE 2 EAD 350865-00-1106 [7] covers fire retardant products (coating) applied in situ.
