A 3300 Series testing machine with a 50 kN load cell and wood shear fixture can determine the shear strength of wood and adhesives that bond wood layers and parts.
Wood's structural use as load bearing beams in various construction applications requires stringent flexural testing
Instron testing machines can follow ASTM D143 and find the strength parallel or perpendicular to the grain, internal bond strength, and cleavage strength for wood.
