The performance of glue laminated railway ties after 40 years of service in the main line track
1989 - IRG/WP 2325
Two series of horizontally glue laminated ties made of a softwood body and topped with a hardwood lamination were creosoted and installed in 1947 in a tangent and a curved main line track. The tests are now 40 years old and the excellent condition of the ties of these two series suggest that a service life of 50-60 years can be expected....

Development of decay in untreated, second-growth Douglas-Fir using two exposure techniques in North Queensland
1997 - IRG/WP 97-20110
The results of two exposure techniques for evaluating the development of wood decay in untreated, mill-run lumber from second-growth Douglas-fir containing both sapwood and heartwood are presented. Nominal 50 mm by 100 mm by 2.5 m (2 in. by 4 in. by 8 ft) lumber, No 2 and better, was obtained from a production run in a mill that was processing second growth, Coastal Douglas-fir in western Oregon, ...

Lignocellulotitic Hymenomycetes from native forest and Pinus elliottii Engelm in the Fontes do Ipiranga State Park, São Paulo, Brazil
1991 - IRG/WP 1468
Results show a distinct microflora for each forest type. A total of 9 families, 45 genera and 67 species were distributed among the two forest ecosystems were studied. Antrodiella, Auricularia, Grammothele, Steccherinum, Stereum and Trametes were found only in the native forest, where Antrodiella hydrophila (Berk. & Curt.) Ryv., Grammothele sp, Phellinus gilvus (Schw.) Pat., Rigidoporus microp...

Development of a method for testing wood preservatives with soft rot fungi
1975 - IRG/WP 250
Although the first publications on experimental soft rot attack date back 20 years ago, so far no test method for evaluating the efficacy of wood preservatives against soft rot attack (Ascomycetes and Fungi Imperfecti) has been generally accepted. The reasons are diverse and the shortcomings and the disadvantages of the methods described are well known and have repeatedly been discussed. The soil ...

Fungicidal properties of boron containing preservative Borosol 9
2004 - IRG/WP 04-30348
The fungicidal properties of new boron containing wood preservative Borosol 9 is described in this paper. These properties were of particular interest as this new boron containing preservative, exhibit very good performance against wood damaging insects. But because the tested boron formulation contain also nitrogen compounds, we wanted to verify if nitrogen as a nutrient could promote...

IRG soft-rot stake test - Site 03 Australia. Progress Report No. 3
1982 - IRG/WP 3202
The performance of test stakes was examined after four (4) years. Hardwood stakes treated with CCA showed significant soft-rot attack. The exception to this was Alstonia scholaris which was similar in performance to Pinus sylvestris. A supplementary test containing stakes treated with CBC, PCP and creosote, showed attack in all hardwoods examined. Little decay was found in stakes of Pinus sylvestr...

Evaluation and approval of wood preservatives in Japan
1988 - IRG/WP 2303
Japanese standardized decay test methods, performance requirements and approving system are briefly described. JIS (Japanese Industrial Standard) A 9302, which is related to a testing method for evaluating effectiveness of wood preservatives when applied to pressure treatment, is fundamentally a sand-block laboratory test method. According to performance requirements in JIS A 9201, mean percentage...

Effect of felling time related to lunar calendar on the durability of wood and bamboo
-Fungal degradation during above ground exposure test for 2 years- (Preliminary report)
2005 - IRG/WP 05-20311
Current study was carried out to know whether the felling time of trees and bamboos based on lunar calendar affects natural durability of felled wood-bamboo or not. Each of one sugi (Cryptomeria japonica) tree of 28 years old and one Moso bamboo (Phyllostachys heterocycla) of around 3 years old was cut 12 times between February and December in 2003. Six sets of sugi tree and bamboo were felled in ...

IRG soft rot stake test. Site: 03 Australia. Progress repor
1980 - IRG/WP 1114
IRG soft-rot test stakes were installed in site 03 Australia 16.6.77. The stakes have been inspected twice, (28.11.78 (Johnson, 1979) and 31.10.79) for signs of decay, and used to obtain fungal isolates. The condition of stakes in the supplementary soft-rot test has also been examined....

A field test with Benzotar, an industrial residue, as a wood preservative
1985 - IRG/WP 3349
Benzotar, a residue of production of benzoic acid, was tested in field as a wood preservative. Results, after 6.5 years of exposure, showed that this product presents properties that improve the performance of wood in ground contact. This paper describes these results and presents a discussion an some aspects of its potential utilization in Brazil....

Decay resistance of high performance biocomposites based on chemically modified fibres
1998 - IRG/WP 98-40120
Different partners within the framework of a European research project produced high performance biocomposites aiming at the utilisation of board materials as durable products both in dimensional and biological degrading circumstances. This paper summarises test data, which indicate the potential of board materials produced with modified fibre material. The chemical modifications applied cover a r...

Investigations on the life cycle and nutrition of Criocephalus rusticus L
1974 - IRG/WP 127
The longhorn beetle Criocephalus rusticus L or Arhopalus rusticus (L) is widely distributed in Europe and Asia. It attacks softwoods. The primary host trees are pines, ie freshly felled, unbarked logs, dying standing trees and stumps. After feeding under the bark the larvae enter the sapwood and also the heartwood. Timber to be used for building purposes may be rendered useless by their tunnelling...

CCA fixation experiments. Part 2
1989 - IRG/WP 3505
CCA fixation in wood was measured by both squeezing solution from treated wood that had not been dried and analyzing the solution for copper, chromium and arsenic, as well as using a chromotropic acid test to detect the presence of chromium VI. Both methods provide useful information on the CCA fixation process and illustrate that chromium VI disappears as CCA becomes fixed within wood....

Natural durability of some commercial timbers of Sarawak, Malaysia in tropical marine environment
2005 - IRG/WP 05-10561
The abundant supply of timber resources in Sarawak makes timber an ideal choice to be used for marine construction. The natural durability of the main commercial timber species of Sarawak in ground contact is well established but the same is not available for marine environment.
This study was conducted to assess the natural durability of 28 commercial timber species in tropical marine environmen...
