Results of chemical analyses in the field of wood preservation in the Bundesanstalt für Materialprüfung
1973 - IRG/WP 321
The results of qualitative and quantitative chemical analyses of wood preservatives are often the basis for evaluating the various works in the field of wood preservation. In the past 10 to 15 years a number of such works was carried out in the Bundesanstalt fur Materialprüfung, Berlin-Dahlem, dealing with the identification and effectiveness of wood preservatives and with methods of wood preserv...

Utilization of nitrogenous substance by Serpula lacrymans
1989 - IRG/WP 1397
When Serpula lacrymans degrades wood, the fungus is considered to have to assimilate nitrogen, which is not abundant in the wood, from the third material. The strands/mycelium has grown into the soil under the floor of the wooden house damaged by the dry rot fungus. The authors analyzed the soil samples collected from the ground under the floors of the dryrotted houses. The samples which were coll...

Study on leaching of a magnesium fluorosilicate product (SF salt) from wood-boards by rain in the open and by artificial shower
1976 - IRG/WP 264
The test was performed in 1961 to obtain information about (1) the comparative leaching effect of natural rain and of artificial shower in the laboratory; (2) the comparative leaching effect on the active ingredient in proportion to the dye-stuff of the product. The results show that a continuos light rainfall with low precipitation has a much stronger leaching effect than short heavy showers with...
