DIN EN ISO 8496:2014-03

This International Standard specifies a method for a ring tensile test of tubes to reveal surface and internal defects by subjecting the test piece to strain until fracture occurs. This test may also be used to assess the ductility of tubes. The ring tensile test is applicable to tubes having an outside diameter exceeding 150 mm and a wall thickness no greater than 40 mm. The inside diameter shall be greater than 100 mm. This document (EN ISO 8496:2013) has been prepared by Technical Committee ISO/TC 164 "Mechanical testing of metals", Subcommittee SC 2 "Ductility testing" (secretariat: JISC, Japan) in collaboration with Technical Committee ECISS/TC 110 "Steel tubes, and iron and steel fittings" (secretariat: UNI, Italy) in accordance with the agreement on technical cooperation between ISO and CEN (Vienna Agreement). Regarding the German collaboration, Working Committee NA 062-01-53 AA "Rohrprüfung für Metalle" ("Mechanical testing of metallic tubes") of the Materials Testing Standards Committee (NMP) is responsible.
