Product Code   

UTM-8400    Cold Test Bending System, 150 kN

 

Standards

EN ISO 15630-1, 7438, EN 10080

 

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.
