B-type veneer

Minimum diameter: 35- 45 cm
Minimum length: 3 m ->
Red heart: max 45% of the end where it appears
Star heart: not admitted
Healthy knots: max 1 knot/ 2 linear meters with a max diameter of 30 mm, located on one side
Cracks: laterally max 1/20 from the diameter; at the end 1/10 from the diameter

Notes:

The minimum diameter is measured at the narrow, bark-free end.

When measuring the wood, for each 1 metre, 1 cm of length.

When the 30-39 diameter beech log is measured, 1 cm of bark will be subtracted from the measured value.

When more than 40 cm diameter beech log is measured, 2 cm of bark will be subtracted from the measured value.
