Strength of European Timber: Part 2. Properties of spruce and pine tested in Gradewood project

Alpo Ranta-Maunus, Julia K. Denzler, Peter Stapel

Research output: Book/ReportReport

Abstract

More than 6000 specimens of spruce and pine grown in several European countries were tested by destructive and non-destructive means in laboratory. Five strength grading machines were also used to test the material. This report includes the description of sampling as well as tension and bending properties of material with comparisons to earlier results. Main purpose of this report is to document experimental results. Analysis in-cludes basic statistical characteristics such as means, coefficients of variation and correlations between grade determining properties and indicating properties. Also the possibility of having same settings in different countries has been focused.
