Current state of world standardization in the toxicometric methods for testing of wood preservatives
2007 - IRG/WP 07-20354
The paper presents an outline of the history of forming standardized toxicometric methods for testing of wood preservatives in the world during last 100 years. Numerous studies resulted in three main methods which are currently used for official and basis assessment of biocides:
- agar-block method in Europe (EN 113);
- soil-block method in the USA and Pacific countries (ASTM D 1413);
- modifi...

The Promotion of Timber and Timber Product uses in China - Government's Role in Regulation and Standardization
2009 - IRG/WP 09-20424
Chinese Government always pays special attention to resource and environmental issues, therefore, resource saving and environmental protection are part of the basic state policies. This paper provides a brief summary of the key policies which guide the practices in promoting timber conservation and efficient utilization in order to meeting social demands of the wood uses. In the paper, the develop...

High-throughput sequencing highlighted contrasted pioneer fungal communities associated to coniferous and deciduous wood preservation assays
2013 - IRG/WP 13-10800
Studying the fungal communities in the wood, in particular during the first events of the colonization, and the factors that underlie the dynamics of fungal species assemblages remain a challenge in ecology, because of the absence of fructification during the pioneer steps of wood degradation. The use of Next-generation DNA sequencing methods, which produce massive volumes of data, provided new pe...

Focus on the European standardization - Towards a revision of the EN 350 natural durability standard: a different approach to the inherent resistance and performance of wood and wood-based materials
2013 - IRG 13-10811
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-bor...

New Standards for Approval of Modified Wood within the Nordic Wood Preservation Council (NWPC)
2017 - IRG/WP 17-20624
In the Nordic countries, there is a long tradition for quality labelling of preservative treated wood. Until now the labelling has been restricted to pine and other easy to treat wood species, but with the introduction of a new set of standards it is now possible to obtain the Nordic Wood Preservation Council’s (NWPC) quality labelling also for modified wood.
In this paper, we will introduce th...

Resistance against marine borers: About the revision of EN 275 and the attempt for a new laboratory standard for Limnoria
2020 - IRG/WP 20-20669
Wood protection technology in the marine environment has changed over the last decades and will continue to do so. New active ingredients, newer formulations, and novel wood-based materials including physically- and chemically-modified wood, together with increasing concerns over environmental impacts of wood preservatives, urgently demand a major revision of EN 275 “Wood preservatives – Deter...
