Abstract: FIELD: non-destructive inspection. 
     SUBSTANCE: method is used for thermal non-destructive inspection of non-uniform structures. Density of thermal flow is created through fence to be inspected and its value q is measured at one of the surfaces (for example, onto internal surface - q i ). Temperatures of opposite surfaces T oi  and T oe  are also measured. Quality of object under control is determined from its resistance to heat transfer R o  according to relation of R o = T i -T e /q= (T i - T oi) /q+ (T oi  -T oe) /q+ ( T oe - T e )/q=R i +R c +R o . Value of density of thermal flow is measured additionally at opposite surface (q i ). Values of densities of thermal flow q o (t) and q e (t) and temperatures of opposites surfaces as well as internal as external surfaces are measured periodically during time interval τ. Admissive error of measurement  of thermal flow density (Δq max ) is specified. Moments of time τ 1 , τ 2 ... τ n  are determined when values of flows at opposite surfaces are equal with error Δq≤ Δq max ,:/q i (t)-q e (t)/≤Δq max . Density of thermal flows is kept to be measured till achieving difference in their values beyond limits of Δq max . Moment t c  is selected from received moments of time where values of densities of thermal flows coincide with preset error Δq max  during longest time interval Δt c.  Quality of object is determined correspondingly to given relation for values q=q i , q e,  T oe,   T oi,  T i  and T e  which were measured at moment t o . 
     EFFECT: improved truth of determination of quality of tested fence.
