ISO 17658:2002, titled "Welding — Imperfections in oxyfuel flame cuts, laser beam cuts and plasma cuts — Terminology," is an international standard that defines terms for possible imperfections occurring in cuts made by oxyfuel gas, laser beam, and plasma arc processes on metallic materials

The standard focuses solely on imperfections directly resulting from the cutting processes mentioned and does not consider defects caused by additional external stresses or strains. It groups the types, shapes, and locations of these imperfections but does not provide conditions, causes of origin, evaluations, or consequences, as these depend on specific job requirements
