PRODUCT DATA / TOLERANCES
Nominal Board Dimensions
Thickness: 20.5 mm (±0.2 mm)
Width: 185.0 mm (±0.5 mm)
Length: 3000* / 2700* / 2400 / 2100 / 1800 / 1500 / 1200 / 900 / 600 mm (±1.0 mm). * Not Black Oak
Drying Method: Kiln dried.
Average moisture content, MC:
Oak (all variants except Black Oak):
8% (±2%)
Black Oak: 9% (±2%).
NH3 treatment of Black Oak means that MC can´t be measured by using a conventional moisture meter but must be measured by the “dry weight method”.
Precision Engineering
Landing Deviation: 0.2 mm (0.3 mm in localised areas).
Board ends are right angled at ±0.3 mm.
