Wood-based panels – Determination of dimensional changes associated with changes in relative humidity
This specifies a method for determining dimensional changes in wood-based panels due to changes in the relative humidity of the air. This is measured between 65% relative humidity and 85% relative humidity in adsorption and 65% relative humidity and 30% relative humidity in desorption. This involves the use of a climate chamber.
