* If the machined panel is smaller than the minimum unit defined in the table (1 m², 1 meter of width), then from the point of view of quality assessment its size shall be equated to 1 m² or 1 meter of width.

* The provided information is for reference only. Wood is a living material, therefore each panel is unique and differences are possible.
