Quality Assurance

The test method is applied to almost every product as a quality assurance tool. The most detrimental unacceptable discontinuities in the objects or items are the surface opening discontinuities.

Visual scanning, inspection or testing can successfully detect these unacceptable surface discontinuities without applying expensive test methods.

Visual testing is performed either by a direct technique or by a remote (that is indirect) technique. The remote technique may include accessories such as mirrors, borescopes, video probes or cameras to correct for the distance or angles of view.

Visual test equipment is designed to detect structural characteristics of a part. These characteristics range from simple surface discontinuities on flat surfaces to various fabrication of inservice discontinuities in complex geometries.
