To appraise the terminal-point conductor wiring connections in terminals and in other applications such as PCB terminals and PCB connectors the standard IEC 60999-1 is used.
In the flexural test, a conductor is connected at the terminal connection point and a weight is then hung from it. In this process, the conductor is then moved 135 times without interruption using suitable testing equipment. During the test, the conductor may not slip out of the connection – and it may not break near the terminal. For a conductor with a 4-mm² cross-section, the prescribed load is 900 grams. No problem for the conductor in our test setup
The tensile test is performed directly after the flexural test. The conductor must be put under a constant strain with a defined pulling force for one minute, with the pull in the direction of wire entry. For a conductor with a 4-mm² cross-section, the pulling force is 60 N. If the conductor withstands the strain for one minute, then the terminal has passed the test. Only when the pulling force reached 220 N, our 4mm² conductor could be pulled out in this test. This is almost the four times the pulling force which the conductor connection needs to resist according to the standard norm.
