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
