Metallic materials - Tube - Ring-expanding test (ISO 8495:2013) EN ISO 8495:2013

Publication date:   May 19, 2014

Scope

ISO 8495:2013 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 thickness from 2 mm up to and including 16 mm.
