a S-basis. The rounded $T_{99}$ values are as follows: $F_{t l}(\mathrm{~L})=61, F_{t l}(\mathrm{LT})=62, F_{t l}(\mathrm{ST})=59, F_{t y}(\mathrm{~L})=57, F_{t y}(\mathrm{LT})=56$ .
b S-basis. The rounded $T_{99}$ values are as follows; $F_{t u}(\mathrm{LT})=62 \mathrm{ksi}, F_{t u}(\mathrm{ST})=59 \mathrm{ksi}, F_{t y}(\mathrm{~L})=57 \mathrm{ksi}$ .
c Standard letter designations for shear properties per ASTM B769: 1st letter refers to grain direction, 2nd letter refers to loading direction.
