Die physikalischen und mechanischen Eigenschaften von Holzfaserhartplatten

Summary

The physical and mechanical properties of hardboard were tested. The following physical properties of specimens conditioned in a standard climate were examined: thickness, density, weight per unit area, moisture content, water absorption in weight per cent and volume per cent and thickness swelling. The maximum linear expansion was tested parallel and perpendicular to the production way. The following mechanical properties of specimens conditioned in a standard climate and of water-soaked specimens were tested: bending strenght, tensile strenght parallel to surface as well as parallel and perpendicular to production way. Harness was also evaluated. The limits, arithmetic means, the standard deviations as well as the frequency of the properties tested were established. The obtained results were compared to those published earlier.
