The European standard EN 350 “Natural durability of solid wood”, Parts 1 and 2, is one of the fundamental standards developed by the CEN/TC 38 “Durability of wood and wood-based products”. This standard is widely used by wood industries as the reference document which provides information on the resistance of wood species used in mainly the construction sector against decay fungi, wood-boring beetles and termites as well as information on wood species’ capacity to be impregnated with wood preservatives. The standard also refers to the appropriate standards for testing these properties of wood and provides criteria of interpretation of such tests’ results. The changes that have occurred over the last few decades on the European market, including the appearance of new wood-based products such as modified wood, the publication and application of new regulations (Biocidal Directive/Regulation, Construction Products Directive/Regulation) and the evolutions of customers’ expectations in terms of the service life of the wood-based products which they may use, make it crucial to initiate a deep revision of the EN 350 standard. The new version would take into account the revisions made recently in related existing standards, the modifications that have occurred on the European market of wood products, and the outcomes of recent national and European research projects in order to provide a robust and relevant decision tool to all those who rely on wood.
