Quality Requirements to Birch Logs
| Quality class | BC | BC | A | |

| Log diameter under bark (cm) | 12-15 | 16-17 | 18+ | 24+ |
| Log length +oversize | 2.7m; 3.2m; 4.8m Minimum oversize 6cm, maximum oversize 30cm |
|||
Minimum oversize allowed if the log end surfaces are free of defects and need not be crosscut again. Maximum diameter of the thickest trunk section measured from the bark 0.6m. |
||||
| Sound knots | Allowed | Allowed | Not allowed | |
| Dry knots | d ≤ 20mm | d ≤ 40mm | Not allowed | |
| Rotten knots | d ≤ 20mm | d ≤ 40mm | Not allowed | |
| Intergrown knots | Allowed | Allowed | Allowed | |
| Epicormic knot | Not allowed | Sound branch d ≤ 50mm and up to 150mm long; dry or rotten d ≤ 20mm wide and 60mm long | Sound branch d ≤ 80mm and up to 240mm long; dry or rotten d ≤ 40mm and 120mm long | Not allowed |
A knot under 10mm is not considered a defect; the knot diameter is measured from the log surface perpendicularly to the longitudinal axis of the log |
||||
| Single curvature | The straightness of the entire log is assessed. Curvature is only allowed for module (1.3 or 1.6m) at the cut 20mm | 40mm (assessed on module) | allowed single curvature of log d < 240mm is 50mm (assessed on module); log d≥ 240mm allowed single curvature 60mm | 50mm (assessed on module) |
| Compound curvature | Not allowed | Not allowed | Not allowed | Not allowed |
A log is too warped if the line connecting log end centres runs outside the log and the module centreline runs beyond another module |
