Water-based wood preservatives for curative treatement of insect-infested spruce constructions
1998 - IRG/WP 98-30171
On laying down sanitation measures for wooden constructions infested by wood boring insects, we must take into account static risks for the construction - and, thus, for the security of the user - as well as risks for humans and environment due to the chemical preservative compounds of the treated wood.
Analyses on many roof constructions made with spruce (Picea abies L.) have revealed that Hylot...

Establishment of a laboratory method to characterise the ecotoxicity of a polluted soil
1998 - IRG/WP 98-50101-23
This method consists in using the underground grub of the Oxythyrea funesta beetle as a bioindicator of the soils pollution.
Due to the significant tolerance of the organism, a large type of substrate of different nature and grain size could have been studied.
We have tested substances and preparations such as wood preservation products even under powder or liquid form but also some wastes of di...

Developing the technical guidance document on data requirements for biocidal products
1998 - IRG/WP 98-50101-02
Finland has been developing a discussion document for EC and the Member States concerning the specified data requirements for 23 biocidal product types, including wood preservatives, and their active substances. This data is required when applying for authorisation for a wood preservative according to the forthcoming Biocides Directive. The data requirements comprise of the core data set, which is...

300 years water-logged wood: Treatability with CCA-C
1998 - IRG/WP 98-40103
The treatability of 300 years water-logged and recent wood (Abies bornmülleriana M.) was assessed by dip treatment and vacuum and pressure cycling with CCA-C. Treatment runs were evaluated on the basis of weight gain retention and radial and tangential penetration measurements. The preservative penetration and retention levels in the 300 years water-logged wood were higher than in the recent wood...

Restrictions or environmental taxes as regulatory means - How will they influence the use of pressure treated wood?
1998 - IRG/WP 98-50101-28
In all the Nordic countries except Norway, we have environmental restrictions on the use of pressure treated wood. In Norway we expect environmental taxes on a large number of various products in 1998/99 - probably also pressure treated wood with one or more of the heavy metals copper, chromium and arsenic.
The paper will discuss how this can influence the use of pressure treated wood and cause a...

Efficacy of anhydrides as wood protection chemicals - II. Performance against soft rot fungi
1998 - IRG/WP 98-30174
Pine sapwood modified with various anhydrides and with butyl isocyanate was tested for its resistance to soft rot decay. Small stakes were exposed for 20 months in unsterile soil in a fungal cellar test.
Wood modified with butyl isocyanate performed better than any of the anhydrides tested, with a threshold level of protection (less than 3% weight loss) at 12% weight percent gain (WPG). Stakes ac...

A survey to assess the current and future usage of timber in British port structures
1998 - IRG/WP 98-10247
Port engineers responsible for 30 British ports were surveyed by questionnaire or interview to establish current and prospective usage of timber in those ports. The ports surveyed account for about 25% of total cargo handled annually in Britain and being located all around the British mainland, were considered to form a representative sample. The survey identified the hardwoods and softwoods in us...

Laboratory investigations about the mobility of some inorganic wood preservatives in soils
1998 - IRG/WP 98-50101-22
Wood preservatives and components of wood preservatives leached from impregnated wood can enter the soil and thus contribute to the pollution of the groundwater. However, there is lack of understanding concerning the interacting parameters of wood preservative, leachate, soil and soil solution. To characterise of the behaviour of active ingredients and for the assessment of their environmental imp...

Results on termite resistance of building materials against Coptotermes formosanus by choice test
1998 - IRG/WP 98-10275
Various building materials, included wood species, wooden board materials, thermal insulation materials and fire-protection materials, were tested for grading of termite resistance against Coptotermes formosanus. The dimension of most specimens were 2x2x2cm3. Ten repeats were prepared. The specimens were put between Akamatsu sapwood control specimens on a laboratory cultured mound colony of termit...
