New Standards for Approval of Modified Wood within the Nordic Wood Preservation Council (NWPC)

IRG/WP 17-20624

N Morsing, E Engelund Thybring, M Klamer

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 the background and criteria for approval according to NWPC for modified wood.
