1 Scope

This standard specifies a method for determining the ability of full-section metallic tubes of circular cross-section to undergo plastic deformation in bending. It is intended for tubes with an outside diameter no greater than 65 mm, although the range of the outside diameter for which this International Standard is applicable may be more exactly specified in the relevant product standard.
Note: Bend tests of the test pieces taken from tubes in the form of transverse strips should be made in accordance with GB/T 232 so as to increase the original curvature of the test piece.
