Computerised data acquisitioning, handling and processing in wood preservation studies
1984 - IRG/WP 2218
The computerisation of data acquisitioning, handling and processing in weathering studies on wood treated with protective coatings is discussed. An integrated system comprising a data base, statistical package and a custom written graphical processor is explained. Two treatments are compared and the correctness of a mathematical weathering model is evaluated....

CCA fixation experiments. Part 1
1989 - IRG/WP 3504
A method of squeezing solution from CCA treated wood that has not been dried at various times after treatment appears to be useful in following the fixation of CCA in wood. Experiments confirm that temperature governs the rate of fixation....

Bacterial staining of samba (Triplochiton scleroxylon)
1988 - IRG/WP 1362
Red- and green-stained areas on Samba wood have been tested by IR, X-ray and Neutron Activation Multielement Analysis. No difference could be seen between stained and unstained areas. The red- and green-staining seem to be related to the bacteria Pseudomonas aeruginosa which were isolated from both red- and green-stained areas on the wood surfaces....
Proposal for further work on fixation of CCA-preservatives in wood
1988 - IRG/WP 3493
Many studies on the fixation and fixation-mechanism of CCA-preservatives in lignocellulose materials have been published but few on the practical consequences of this knowledge. For the wood preserving industry and the user of treated wood it is important to know what is meant by the word fixation, when fixation is complete and how fixation can be recorded in an easy way according to a non-destruc...
Environmental aspects of wood preservation
1987 - IRG/WP 3406
The preservation industry employs a wide range of chemicals and processes to provide timber commodities capable of resisting biodeterioration and degradation. The public often perceives the chemicals as health hazards and treatment plants as potential threats to the environment. This paper attempts to place in proper perspective the value of wood preservation. It discusses aspects of health and sa...
Safe handling of solvents in relation to classification and labelling
1990 - IRG/WP 3569
The classification and labelling of chemical products, safety data sheets and personal protective equipment are topics which at present are given a very high priority in Denmark. The area is very large and may seem extremely difficult to comprehend. The frequent publication of acts and announcements from the authorities does not make the work any easier. In the following I will try explain how we ...
Recommendations for handling of mold infestation of wooden artifacts
2012 - IRG/WP 12-10790
The presentation gives an overview of the handling of wooden artifacts with mold infestation. The causes of mold deterioration are demonstrated by investigations in a church, a historic library and a monastery in Germany. Investigated infested wooden artifacts were altars, sculptures, picture frames and sarcophagi. Important investigation methods including indoor climate measurement, material an...

Best handling practices for wood crossties (sleepers)
2015 - IRG/WP 15-40714
Wooden crossties (sleepers) dominate the rail industry in the USA. Most ties are hardwood treated with oil-borne preservatives using pressure treatment. Incipient decay (called ‘stack burn’) commonly develops during the pre-treatment drying process and reduces tie performance and longevity. Practices to minimize stack burn and enhance wooden tie performance are discussed as an aid to non-wood ...
