EN 16873:2016 (E) 4 Introduction The successful management of archaeological wood finds from waterlogged sites starts in the planning phase of any excavation. From the moment of exposure, waterlogged wood finds are extremely vulnerable to a range of man-made and natural threats. There is a real risk of losing the artefact if it is not handled and conserved properly. To minimize these threats and prevent damage, several actions shall be taken in the field which shall include proper management of the site and handling of the finds. These activities should be carried out by professionals, specifically qualified in the management and handling of waterlogged archaeological wood. SIST EN 16873:2017



EN 16873:2016 (E) 5 1 Scope This 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
controlled reburial, in situ preservation, long term post excavation storage or excavations under water. Composite artefacts, and other waterlogged materials are specifically excluded from this standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. Not applicable. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 deposition archive formal handing over of the entire excavation record, including the conserved artefacts, to a museum or other receiving institution 3.2 block-lifting removal of a fragile find by lifting from the ground with surrounding burial matrix, with or without extra support, limiting the risk of damage 3.3 burial matrix soil, peat, sediment or other medium found in direct contact with an artefact 3.4 cleaning removal of unwanted material from an object Note 1 to entry the criteria for something being “unwanted” always have to be stated, e.g. potentially damaging, obscuring detail, un-aesthetic [SOURCE: EN 15898:2011, definition 3.5.3] 3.5 condition physical state of an object at a particular time [SOURCE: EN 15898:2011, definition 3.2.1, modified, Note 1 to entry deleted] 3.6 conservation active remedial treatment of waterlogged wooden finds designed to prevent further deterioration or degradation and bring them into a stabilized condition for research, archiving or museum display SIST EN 16873:2017



EN 16873:2016 (E) 6 3.7 controlled reburial systematic redeposition of finds at the original excavation site or another appropriate location for the purposes of their long term preservation 3.8 cushioning provision of soft but stable packing or padding material beneath and around fragile artefacts to provide protection, support and shock absorption, so as to mitigate the risk of damage during lifting, handling and moving 3.9 degradation result of the process of wood deterioration through physical, chemical and biological factors 3.10 discarding disposal of wood material through the considered application of a selection and retention policy 3.11 in-situ preservation maintaining finds in their original context whilst monitoring and controlling factors influencing degradation in the burial matrix 3.12 labelling process of fastening a label or tag carrying a unique identification number or code onto the artefact and/or its packaging 3.13 lifting removal of an artefact from its buried position in the ground Note 1 to entry: Lifting techniques aim to support and protect the wood surface and overall structure. 3.14 maintenance periodic preventive conservation actions aimed at sustaining an object in an appropriate condition to retain its significance [SOURCE: EN 15898:2011, definition 3.4.1, modified, examples deleted] 3.15 post excavation storage long term maintenance off-site before commencement of further recording, analysis and conservation treatment 3.16 preservation by record data generated from a process of documentation will become the only evidence of a find after it has been discarded SIST EN 16873:2017
