This draft European Standard provides guidelines for safeguarding waterlogged wood on terrestrial sites of archaeological or historical significance. It deals with the protection of archaeological and historical waterlogged wood, from the time of exposure during and after excavation, until it reaches the conservation laboratory. The standard cannot be applied to the management of underwater sites, controlled reburial, in situ preservation, or long term post excavation storage. Composite artefacts of wood and other materials are also excluded from the standard.
