Embedment tests parallel-to-grain using dowels with different steel grades and five wood species were carried out. The specimen sampling with regard to density was random and the specimens were tested at different moisture contents. Furthermore, own tests were extended by results from literature. Observed ductility aspects using different wood species are discussed. Comparisons with the existing design equation in Eurocode 5 were made. It was found that the equation penalises species with higher densities. An adjustment of density and embedment strength to 12 % moisture content reduced the scatter considerably. Moreover, based on the test results, the sophisticated distinction of softwood in many strength classes based on minor differences in density is considered to be overly precise as far as embedment strength is concerned. An influence of the dowel steel grade was measured although the dowels remained elastic as required by standard embedment test protocols.
