EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 10274 testing. This European standard specifies the drop weight tear test for metallic materials and includes a method for assessing the fracture appearance of ferritic steels. The assessment may also be based on the energy absorbed in breaking the test piece, especially for materials other than ferritic steels.
The test is usually carried out on test pieces taken from plate for pipe manufacture or pipe with an outer diameter of 300 mm and a thickness of more than 6 mm.
The test involves breaking a test piece containing a pressed notch by being supported at its ends and striking the back of the notch. The test is performed at a specific test piece temperature.
Unless otherwise specified in the product standard, the test piece can be straightened completely for testing purposes or left with the original tube curvature of 50 mm in the center. In the latter case, the mid-thickness in the center of the test piece should be in the same plane as the mid-thickness in the anvil supports.
A temperature-controlled environment should be provided in which the test piece can be immersed in an environment suitable for temperature conditioning prior to testing. Circulation of the medium must be ensured to ensure a uniform soaking temperature.
The test piece should be placed in the testing machine with the centerline of the notch aligned with the centerline of the hammer. The test piece shall be suitably restrained to prevent out-of-plane rotation during or after impact.
