Metallic materials. Tube. Ring-expanding test Ingestion-build-51747 Simplified method1 Scope This International Standard specifies a method for a ring expanding test on tubes, that is used to reveal defects both on the surfaces and within the tube wall by expanding the test piece using a conical mandrel until fracture occurs. It may be also used to assess the ability of tubes to undergo plastic deformation. The ring expanding test is applicable to tubes having an outside diameter from 18 mm up to and including 150 mm and a wall
