This standard applies to the calculation of log volume of all tree species. The volume of small-diameter logs with a gauge diameter of 4 to 12 cm is determined by the formula.
V=0.7854L (D+0.45L+0.2)2+ 10,0002The volume of logs with a gauge diameter of more than 14 cm is determined by the formula UDC 634.0.52

V=0.7854L［D+0.5L+0.005L2 +0.000125L(14-L)2.(D-10)) 2 +10,000.
V-- volume, m3;
In the two formulas:
L-- length, m3
D-- diameter, cm.
3The length and diameter of logs shall be measured in accordance with the provisions of GB144.2-84 "Log Inspection Dimensions and Measurement". 4The volume of logs with a diameter of 4 to 6 cm shall be retained to four decimal places, and the volume of logs with a diameter of more than 8 cm shall be retained to three decimal places.
