METHOD TO ENSURE SPECIFIED LEVEL OF ITEM RELIABILITY BASED ON CONTINUOUS MONITORING OF OPERATIONAL LOADS AND NON-DESTRUCTIVE CHECK BY ITS READINGS Russian patent published in 2014 - IPC G01N17/00 

FIELD: testing equipment.

SUBSTANCE: invention relates to methods of testing, in particular, for assessment and improvement of reliability indices of an item. To ensure level of item reliability they detect its initial condition by characteristics of residual imperfection. Further quantitative monitoring of reliability is carried out on the basis of continuous monitoring of operational loads. If new probabilities of damage, leak or other dangerous event thus defined become unacceptably high, operation of the item is stopped, and control of its condition is carried out with non-destructive methods and further repair of detected defects that are not permissible in operation. After that they determine a new position of a residual imperfection curve and perform the subsequent operation until the level of reliability reduces to unacceptable values.

EFFECT: invention achieves increased resource of an item.
