ISO 8493 – Metallic Materials — Tube — Drift-Expanding Test
ISO 8493 – In the drift-expanding test, a conical mandrel is pressed into a tube specimen via materials testing machine according to the tube’s inner diameter and
the tube is expanded.
The test is ended when the value of the expansion defined in the specifications has been reached.
The test is considered passed if no cracks are detected in the tube or at the welded seam after the test.
The drift-expanding test is normally performed on tubes having an outside diameter of 150 mm and a wall thickness no greater than 10 mm.For tubes without
a detectable welded seam, the drift-expanding test is used as a replacement for the tube-flattening test.
*** Before conducting this ISO standard , it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
***PARSROS offers several types of grips and fixtures which will enable you to perform a variety of tests
that are accurate and repeatable
