Environmental Emission of Wood Preservatives: Interpretation of Data Relevant to BPD Risk Assessments
2009 - IRG/WP 09-50259
The risk assessments for the use of wood preservatives proposed by the OECD and used under the Biocidal Products Directive (BPD) (98/8/EC) require the derivation of leaching rates for active substances. These rates are to be used as input data in to agreed exposure scenarios. The leaching rates can be derived from laboratory testing and from field testing. The relationship between laboratory and f...

Field trials of wood preservatives in UC3 retention. Part 1. Durability results after 13 years in and above ground
2010 - IRG/WP 10-30548
In 1996 an extensive field trial program was set up in order to obtain more data on wood treated with chromium and arsenic free preservatives in Use Class 3 retention. Apart from durability in and above ground, other features were also assessed, e.g. discoloration by staining fungi, depletion of active ingredients, weathering and corrosion of fasteners in con¬tact with the treated wood. Wood spec...

Durability of modified wood in UC3 and UC4. Results from lab tests and 5 years testing in 3 fields
2011 - IRG/WP 11-40562
In 2005 an extensive test program including field tests was set up in order to obtain more data on the durability and long term performance of modified wood and semi-durable wood species. One of the main challenges for modified wood is to predict accurate service life time in UC3 (use class 3, above ground) and UC4 (use class 4, in soil or fresh water contact). So far, data from in-service condi...
