Historical Version s – view previous versions of standard. The bend angle can be measured while the specimen is under the bending force usually when the semi-guided bend test f290 employedor after removal of the force as when performing a free-bend test. The convex side of the specimen is visually inspected for cracks or defects, and failure is determined by the size of the cracks and imperfections allowed by the material specification.

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 asym 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; asm free-bend test in which the ends of the specimen are asgm 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.

The guided bend test method requires the specimen to be loaded at its center point with a mandrel or plunger while being asmt at the ends. Subscribe to Instron News!

The loading supports are held together with two tie rods to provide extra stiffness during loading. Email addresses must contain the symbol.

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 convex side of the specimen is visually inspected for cracks or defects, and failure is determined by the size of the cracks and imperfections allowed by the material specification.
