For correct weigth estimation the density must be given per thickness, for a calculation method see 11016\our files\11016.xls. Naming in database will be:
- 3 letter abbreviation - for bare plywood bare ocoume: OCO
- 3 letter abbreviation / upper score / 2 digit thickness of bare sheet - plywood + HPL (HPL is always on both sides of panel) sheeted birch plywood of 9mm thickness: BIR-09
