Researchers recommend new EU standards for machine strength grading of timber

To ensure that wooden constructions are sufficiently stable, timber must first be graded according to its strength. Machines for this already exist, but they are rarely used in Europe as current EU standards stipulate expensive acceptance requirements. That's why timber is usually classified visually -- which is slower and less accurate. German wood technologists have now identified how the obstacles to machine grading can be overcome. This should make timber a more competitive, safer construction material.
