Application Summary AI generated

This standard specifies a method for evaluating the ability of metal tubes to undergo plastic deformation when a conical mandrel is forced into the tube end. It is applied in the metallurgical and manufacturing industries to test the ductility and quality of seamless and welded tubes, particularly for applications in piping systems, boilers, and pressure vessels. The test is used for quality control and material acceptance to ensure tubes can withstand flaring or expansion during fabrication or service.
