Status of Work on OECD Test Guidelines for Emissions of Wood Preservatives to the Environment
2005 - IRG/WP 05-50224-3
In April, 2003, OECD published an ESD on wood preservatives that provides guidance on how to estimate emissions: 1) during the wood preservative application processes and storage of treated wood prior to shipment; and 2) from treated wood-in-service. The ad hoc Expert Group that developed the wood preservatives ESD identified the need to develop Test Guidelines to estimate the amount of biocides ...

Validation of the sapstain danger index
2000 - IRG/WP 00-10333
The Sapstain Danger Index (SDI) is a model that is used to indicate sites in the New Zealand forest where felled logs are more prone to sapstain, specifically it should indicate how soon after felling of a log should it be treated for sapstain. The validation of SDI has the goal to identify whether the SDI can be used to predict sapstain development and to eventually minimise loss of value of logs...

Validation by micro-computed tomography of an assessment method to measure the residual strength of anobiids infested timber
2019 - IRG/WP 19-20650
In this article a quantitative correlation study of pine timber structural elements, which have been subject to attack by anobiids, is presented. The main objective of the study was to establish a valid empirical correlation between the lost material percentage (consumed by beetles) and original/residual apparent density. Since the beetles’ attack produces a diffuse damage with a set of tunnels ...

Improvement of analytical methods of wood preservatives and its validation with collaborative testing
2019 - IRG/WP 19-20655
This discussion paper presents on-going collaborative test of analytical methods of wood preservatives according to the standardization process of Japan Agricultural Standard (JAS) by the Ministry of Agriculture, Forestry and Fisheries (MAFF). Food and Agricultural Materials Inspection Center (FAMIC) in close cooperated organization with the MAFF, has wide range of tasks about inspections and anal...

A multi-dataset validation study of moisture prediction in Norway spruce wood exposed outdoors
2025 - IRG/WP 25-41029
Wood used in outdoor construction undergoes continuous cycles of wetting and drying, resulting in fluctuating moisture contents that directly influence its long-term durability. Excess moisture above a critical threshold leads to deterioration by fungal decay, limiting the service life of the structure. Service life models thus rely on accurate predictive models of moisture behaviour. However, cap...

Validation of a measurement method for cyproconazole retention in pressure-treated wood through an interlaboratory study
2025 - IRG/WP 25-41037
The Japanese Agricultural standard (JAS) defines national regulations for preserved wood and wooden materials, in Japan. Traditionally the JAS focused on quality of product, however, the revision of the JAS Act in 2017 enabled standardisation of test or measurement method for the quality evaluation. The Japan Wood Protection Association (JWPA) has been working toward standardisation of methods for...
