Visual testing (VT) is the oldest and most widely used non-destructive testing method. The inspector examines a part directly or with aids to find surface discontinuities, verify dimensions and assess condition, using adequate lighting, access and visual acuity.

Adequate lighting (a minimum illumination at the surface), suitable viewing angle and distance, access to the surface, and an inspector with verified visual acuity. Codes often specify a minimum light level and periodic eye examinations.
