3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 17677-1 and the following apply.
3.1
impact cross-tension failure energy
failure energy obtained from the impact cross-tension testing
3.2
impact cross-tension strength
maximum impact force obtained in the impact cross-tension testing
3.3
impact tensile shear failure energy
failure energy obtained from the impact tensile shear testing
3.4
impact tensile shear strength
maximum impact force obtained in the impact tensile shear testing
4 Test specimen
The dimensions and form of the impact tensile shear test specimen are shown in Eigj.treJ. and Tabki.
The positional accuracy of the weld on the test specimen shall be ±1 mm or less in every direction.
The dimensions and form of the impact cross-tension specimen are shown in Figure 2 (see ISO 14272).
An example of a jig for welding the impact cross-tension specimen is shown in Eiguic.3. Two punched strips are placed at right angles to each other, held in the jig, and welded together.
5 Test equipment and testing procedure
5.1 General
Testing can be accomplished with an appropriate impact-testing machine. If needed, the load can be obtained using hydraulic test equipment.
The pendulum-type machine is generally used for a sheet thickness range of 0,5 mm to 3 mm, and the drop-weight machine for a sheet thickness range of 1 mm to 4 mm.
The minimum number of specimens tested shall be five.ISO 14323-2015 pdf free download.
