Cold Test Bending Machine
UTM-8400
UTM-8400 Cold Bending Machine is used for bending and re-bending tests of reinforcing bars, wire rod and wire for concrete in accordance with the requirements of EN ISO 15630-1.
The test piece is bent over a mandrel.The angle of bend and the diameter of the mandrel (D) is selected in accordance with the relevant product standard EN 10080.
The bend test is performed with a minimum angle of bend of 180° over a mandrel.according to EN ISO 15630-1.
For re-bend test, first the test piece is bend with a minimum angle of bend of 90° over a mandrel, in a second step, the aging treatment is applied and than the test pieces bent back up to a minimum of 20°. according to EN ISO 15630-1,
After the tests, the tension (lower) side of the test piece is visually inspected for cracks or fissure visible to a person with normal or corrected vision. .
The test piece is inspected for cracks and fissures visible to a person with normal or corrected vision.
Mandrels for bent and re-bend tests should be ordered seperately.
