Quality Control in Plywood Manufacturing Water Absorption after 24 Hours

Samples were weighed and then immersed in water for 24 hours and, subsequently, removed and weighed again. Absorption (A) in water after 24 hours (Equation 1) was obtained following assumptions and calculation methods of ABNT NBR 9486, using 6 specimens per panel.
