Strength data of Italian grown spruce that has been gathered during various research projects over the last 13 years have been combined into one large dataset. The data has been analysed for mechanical properties such as bending strength, modulus of elasticity as well as density. Visual grades have been determined using the German and Italian standards and were analysed for their strength profiles. Normal, Lognormal and Weibull distributions have been determined. The use of ultrasound grading as an additional parameter has been tried, but was found not very useful in improving the yield in higher strength classes.

Abstract
Strength data of Italian grown spruce that has been gathered during various research projects over the last 13 years have been combined into one large dataset. The data has been analysed for mechanical properties such as bending strength, modulus of elasticity as well as density. Visual grades have been determined using the German and Italian standards and were analysed for their strength profiles. Normal, Lognormal and Weibull distributions have been determined. The use of ultrasound grading as an additional parameter has been tried, but was found not very useful in improving the yield in higher strength classes.
