Wood-based panels – Determination of moisture content

This standard specifies an oven dry method for determining the moisture content of test pieces of wood-based panels.  These results may be used to estimate the moisture content according to EN 326-1 : Wood-based panels – Sampling, cutting and inspection – Sampling and cutting of test pieces and expression of test results.

Determination, by weighing, of the loss of mass of each test piece between its state at the time of sampling and its state after drying to constant mass at 103°C (±2°) and calculation of this loss of mass as a percentage of the mass of the test piece after drying.  These results are used to estimate the moisture content of the whole panel.
