Wood Preservation in the Federal Republic of Germany

IRG/WP 3157

R Cockcroft, H Willeitner

The report gives some statistics about the forest products industries in the Federal Republic and a general review of the wood preservation industry. The trend in the use of wooden railway sleepers is decreasing, as is the use of poles. The sale of other pre-treated timber, mainly fence posts, palisades and domestic fences, is however slightly increasing. Apart from the use of pressure treatments for poles and sleepers, dipping, deluging and spraying are the most common methods of treatment used. For constructional timbers the treatment given is often only of a poor quality. A glossary of the treatments used is given and a list of the firms supplying approved preservatives. Information is given for applicants who wish to have preservatives approved for use in the Federal Republic. All wood preservatives have to be registered for the treatment of any constructional timber which relates to the strength of a building. New types of biocides will obtain approval only after special tests have been carried out to ensure their long term effectiveness. The approved State Laboratories which can issue test certificates and organizations which can give useful advice to users of treated wood are listed, together with the addresses of some other organizations. The report lists all the relevant German standards.
