Glued laminated poles - Progress report after 43 years of testing
2023 - IRG/WP 23-20692
In 1979, a number of glued laminated poles treated with CCA and creosote were placed in a greenhouse in Uppsala, in the Simlångsdalen test field in south-western Sweden and in a power lane in Vuollerim in northern Sweden, in order to study their resistance against biological degradation.

Field test methods as long-term aging – report of selective wood properties
2023 - IRG/WP 23-40962
Wood samples from a long-term field test are a valuable compendium of information about the material in the context of its aging processes. In the current work, wood samples from the round-robin test within the ECOMOD project were used as a material for the natural aging process (III and IV class of utility). The research scope was to determine selected properties of this wood which can be partial...
