Abstract The author's procedures and methods were described for compiling General Volume Tables for teak, from which Local Tables can be derived. Only easily and rather accurately measurable characteristics should be used: tree height, length of trunk free of branches and timber-yielding length of trunk and trunk girth at 1.30 metre. Girthes at 1.50 metre and 1.70 metre were also necessary, to avoid abnormal trunk bases. The Table should also contain estimated volumes of whole tree and its parts with bark, and diameter, girths and volumes of the tree without bark at different heights.

But more data were needed to construct the Table, primarily the mathematical expression of the trunk form. Two true form quotients are required to represent the trunk form of teak with satisfactory accuracy in a simple equation. Estimation of the form class of an individual tree was only possible by direct measurements, so average form classes were used. These classes for the various trees and stands of one single kind of wood usually varied so little that for any one Table practically only one form class was required. The slight variation in form class of teak can easily be incorporated in the Volume Tables.
