2.4. Determination of mechanical properties of particleboard
The modulus of rupture (MOR) and elasticity (MOE) of the samples were performed according to EN 310 standard [13]. A total of twenty samples with dimensions of 410 mm × 50 mm × 18 mm were tested for each type of particleboard. The internal bond strength (IB) tests were conducted on the samples cut from the particleboards according to EN 319 standard [14]. 20 Replicate samples with dimensions of 50 mm × 50 mm × 18 mm from each type of particleboard were used to determine the internal bond strength.
