- Defects and defects of wood processing
- Deviations from nominal dimensions and geometric shape
- Conformity of appearance, completeness, packaging, labeling
- Adhesion of the paintwork (the method of lattice incisions)
- Vertical load resistance
- Torsion resistance under static load
- Impact resistance with a soft heavy body
- The resistance of the door leaf to impact by a solid body is the force required to open the door block leaf
- Reliability
