Acceptance Inspection and Preceding to It Types of NDT

A. K. Gurvich

Methodology for creating the acceptance NDT systems for industrial products inspection is described. The methodology is based on overall effectiveness criterion which represents correlation between technical efficiency ΔG of NDT system and total expenditures EΣ that enable this efficiency to be achieved. Technical efficiency of the system is estimated with regard to defect type and possibility of formation of defects that are to be detected in objects of certain type, their potential risk and of its detection probability by means of NDT system. Extended expressions for determination of ΔG and EΣ and correlation for creating effective NDT systems to inspect objects of various categories of responsibility are given.
