Visual inspection is classified as what type of testing?

Visual inspection is classified as a non-destructive test because it does not alter or damage the material or component being evaluated. This method allows engineers and inspectors to assess the condition, quality, and integrity of an item without compromising its usability. For instance, visual inspections can identify surface defects, corrosion, and overall workmanship by simply examining the surface characteristics of the material.

Non-destructive testing methods, like visual inspection, are essential in many industries as they enable the detection of potential issues that could lead to failure, all while maintaining the integrity of the components under inspection. In contrast, destructive tests involve methods that permanently damage or alter the material, making it unfit for future use, which is not the case with visual inspections.
