Notes:

Shaded cells – Essential characteristics which must be determined

Non-shaded cells – Performance characteristics determined only if required

1 Plywood should be used out of direct contact with the ground, soil or water

2 For use in humid conditions only

3 Tests for strength & stiffness in tension & compression, panel shear (Modulus of Rigidity), panel shear, planar shear (Modulus of Rigidity), & planar shear stregth

4 Only relevant when intended for structural floor or roof decking on joists

5 Relevant only for use as wind barriers
