Notes:
Shaded cells – Essential characteristics which must be determined
Non-shaded cells – Performance characteristics determined only if required
1 For use in humid conditions only
2  Tests for strength & stiffness in tension & compression, panel shear (Modulus of Rigidity), panel shear, planar shear (Modulus of Rigidity), & planar shear strength
3  Only relevant when intended for structural floor or roof decking on joists
