METHOD TO DETECT MASS SPEED OF WOOD BURNING IN BUILDING FLOOR Russian patent published in 2014 - IPC G01N25/50 

FIELD: construction.

SUBSTANCE: method suggests detecting mass speed of wood burning when testing a wood structure of a building without fire impact by non-destructive methods according to complex of its single quality indices under conditions of complicated gas exchange. For this purpose they determine position of wood structures in the space of the building, geometric dimensions of wood structures, conditions of heating of rated cross sections of wood structures under conditions of fire, limit thickness of charring layer, density, strength and moisture of wood in natural condition. The sought for value of wood burning speed is determined under conditions of complicated gas exchange depending on the index of cellular floor cell opening.

EFFECT: increased validity of control of quality of construction wood, wood structures.
