Tiivistelmä
The purpose was to find out the reasons why there are a number of problems with quality estimation of timber patterns imported from Finland to Russia, to study why European quality grades could not be simply equal to Russian quality sorts. Russian specialists have to produce similar procedures of quality estimation right from the beginning, which requires additional working hours and increases costs.
In the theoretical part of the study the main issue was to find the differences between main normative documents about sawn and planed timber from two sides: Russian GOST and Finnish SFS. Previous studies have indicated that the lists of defects and definitions are similar, but there are essential differences between the limit values of the defects in processes of quality estimation. In the empirical part of the study the main concern was to estimate the patterns of wood production in the Russian and the Finnish way and to compare the results. The empirical part consists of practical measurements on site.
As a result of this project it could be stated that European and Russian algorithms of quality estimation of sawn and planed timber products are similar and based on the same principle, but juristically European grades could not be simply converted into Russian ones, deeper analyses are need. May be reasons was declared and little support was found for the creation of a united juridical document in sector of sawn and planed timber quality estimation and more widely – timber international trading between Russia and Europe.
