We have no amendments or corrections for this standard. The bend test helps provide a visual indication of the ductility of the material.
Link to Active This link will always route to the current Active version of the standard. If the specimen astmm, the material has failed the test.
When complete fracture does not occur, the criterion for failure is the number and size of cracks or surface irregularities visible to the unaided eye occurring on the convex surface of the specimen after bending, as specified by the product standard. The guided bend test method requires the specimen to be loaded at its center point aetm a mandrel or plunger while being supported at the ends.

Email addresses can only contain letters, numbers and the following special characters: Included in the procedures are four conditions of constraint on the bent portion of the specimen; a guided-bend test using a mandrel or plunger of defined dimensions to force the mid-length of the specimen between two supports separated by a defined space; a semi-guided bend test in which the specimen is bent, while in contact with a mandrel, through a specified angle or to a specified inside radius r of curvature, measured while under the bending force; a free-bend test in which the ends of the specimen are brought toward each other, but in which no transverse force is applied to the bend itself and there is no contact of the concave inside surface of the bend with other material; a bend and flatten test, in which a transverse force is applied to the bend such that the legs make contact with each other over the length of the specimen.
When complete fracture does not occur, the criterion for failure is the number and size of cracks or surface irregularities visible to the unaided eye occurring on the convex surface of the specimen after bending, as specified by the product standard.

ASTM E/ISO metal bending – Bending/Flexure – United Test
Our advanced control electronics offer the best in responsiveness, data accuracy, and resolution. As the voice of the U. The loading supports are held together with two tie rods to provide extra stiffness during loading. ASTM E covers bend testing for ductility of materials.
Discover simpler and smarter testing with features such as pre-loaded test methods, QuickTest in seconds, enhanced data exporting: Subscription pricing is determined by: The bend angle can be measured while the specimen is under the bending force usually when the semi-guided bend test is employedor after removal of the force as when performing a free-bend test.
The guided bend test method requires the specimen to be loaded at its center point with a mandrel or plunger while being supported at the ends.

Standard Test Methods for Bend Testing of Material for Ductility
Product requirements for the material being tested determine the method used. Additionally, digital calipers can be interfaced with the testing system for push button input of crack measurements. If the specimen fractures, the material has failed the test. The convex side sstm the specimen is visually inspected for e2990 or defects, and failure is determined by the size of the cracks and imperfections allowed by the material specification.
