Sawn timber volume table
1 Scope
This standard specifies the method of calculation and volume of sawn timber sawn timber volume.
This standard applies to general and special sawn lumber volume calculation and check the set.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research
Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.
GB/T 153 conifer sawmills
GB 154 sleepers
GB/T 4817 Broadleaf Timber
GB 4820 tank Woods
GB/T 4822 Test sawmills
LY1200 machine wood

3 Timber volume calculation method
Timber volume according to equation (1).
Vp = L × W × T/1000000 (1)
Where.
Vp --- sawn timber volume, in units of cubic meters (m3);
L --- sawmills length in meters (m);
W --- sawmills width in millimeters (mm);
T --- sawn thickness, in millimeters (mm).
4 sawn timber volume table
4.1 Common sawn timber volume table
4.1.1 Common sawn timber volume table shown in Table 1.
4.1.2 Table 1 applies to material long 0.5m ~ 8.0m, sheet width 30mm ~ 300mm, material thickness 12mm ~ 100mm sawn timber of all species
Product search volume set.
4.1.3 sawn timber size according to the provisions of GB/T 4822 for calibration.
4.1.4 sawn timber length and width into the timber to perform the required level GB/T 153 and GB/T 4817's.
4.1.5 volume calculations to 2.0m in length or less material retained five decimal places; length from 2.0m above material retained four decimal places.
