1.This standard specifies the method for a ring tensile test of metallic tubes to reveal surface and internal defects by subjecting the test piece to strain until fracture occurs. This test is also used to assess ductility of the tubes.
1.1 The ring tensile test is applicable to tubes with outside diameter exceeding 150 mm and wall thickness not greater than 40 mm. The inside diameter must be greater than 1 00 mm.
