Any imperfection which is found by the inspector is called a discontinuity until it can be identified and evaluated as to the effect it is going to have on the service of the part or to the requirements of the specification. Defect normally results into material rejection.Ī discontinuity is not necessarily a defect. On the other hand, a defect is a flaw or flaws which by nature or accumulated effect render a part or product unable to meet minimum applicable acceptance standards or specifications. crack, porosity, and inhomogeneity etc.). ![]() Then, those discontinuities are evaluated according to an acceptance criterion to determine whether the material is to be accepted or rejected.Ī discontinuity is an imperfection or interruption in the normal physical characteristics or structure of a material (e.g. During the inspection, the inspector looks for the discontinuities in the material and identifies their nature and size. The aim of an inspection is to determine if the material being inspected is to be accepted or rejected.
