Laboratory evaluation of metallic naphthenates as wood preservatives
1991 - IRG/WP 3654
Fungicidal and termiticidal efficacy of copper and zinc naphthenates was appraised according to Japanese standardized laboratory testing methods. Copper and zinc naphthenates succeeded in protecting wood from decay fungi at retentions of 0.5 and 1.0 kg/m³ as metal, respectively. [JIS A 9302 (1976)] when they were applied to vacuum/soak impregnation [JIS A 9301 (1976)]. With respect to the fungici...

Evaluation of a new anti-sapstain formulation
1994 - IRG/WP 94-30035
A new anti-sapstain mixture, which consists of 2% IPBC (3-iodo-2-propynylbutyl carbamate) and 1.5% DCOI (4,5-dichloro-2-n-octylisothiazolin-3-one), was evaluated by three methods in the laboratory. A standardized test (JWPA standard 2) demonstrated that the new anti-sapstain formulation was highly effective in controlling growth of monocultures of five test fungi on wood substrate. When exposed to...

Durability evaluation of outdoor-exposed CLT treated with various wood presevatives using CT scans
2025 - IRG/WP 25-41035
Methods for wood preservation treatment of large materials such as Cross Laminated Timber (CLT) are limited. It is unclear which wood preservation treatment methods can effectively protect CLT from rot risk. In this study, accelerated rot tests (fungus cellar test) of CLT treated with the solvent-borne wood preservative by non-pressure treatment, named ‘deep penetration treatment’, were conduc...
