## ISQI Approach
In NDT services, performing the test alone is not the ultimate objective; rather, the proper selection of the method, quality of the resulting data, interpretation of the results, and their relationship to the actual condition of the equipment are of fundamental importance.
ISQI, taking into consideration the type of defect, damage mechanism, material and geometry of the equipment, service conditions, and standard requirements, selects the appropriate testing method and evaluates the results within the framework of the project’s technical requirements.
The combination of conventional and Advanced NDT methods, including MFL, IRIS, Eddy Current, PAUT, TOFD, and TFM, enables access to more accurate information for decision-making regarding equipment repair, monitoring, integrity assessment, and continued operation.
