Description of the plywood sheets with the marks MO, MH, MK

• MO – the one-sided plywood with a local function. One-sided means that this sheet has only one side that conforms to the certain kind of plywood, and another side doesn’t because of the presents of defects. Defects can be different – local or total absence of the cover level, mechanical flaws and others. So – the presence of any defects on the other side is out of court.
• MH – local function plywood, ill-conditioned. This plywood has no sort or kind; those are the sheets with internal defect (bubbles).
• MK - local function plywood compositional. The word “compositional” here means that under the cover sheet of this plywood, there is a sub layer made by rotary-cut veneer. The external cover-layer has to correspond to the sort IV/IV of all-Union State Standard 3916.1-96
