Remote Visual Inspection (RVI) is a Non-Destructive Testing (NDT) technique used to detect and examine a variety of visible flaws; such as cracks, corrosion, contamination, structural integrity, and other discontinuities. Remote visual inspections also often provide supplemental information for other NDT methods. Remote Visual Inspection is by far the most common and relatively simple NDT technique. Visual Testing (VT) is usually the first choice of any inspection as it offers an immediate and less costly approach as compared to other NDT methods. There are three levels of visual testing, each level has specific requirements.
