Test terminal blocks a measure of the detection of mechanical strength, the terminals must go through rigorous product validation tests and periodic production type of experiment in order to ensure the safety and reliability during operation.

After the test, if the wire does not slide out terminal clamping, there is no clamping Sakon fracture, the level gauge pressure line terminal solid is pass. If there is a wire break perhaps off the terminals of the clamping mechanism is failing.

Drawing the goal of the experiment is to test terminal to the wire is firmly clamped between the metal appearance. The type of terminal access rules and the additional cross-sectional area of conductor, the choice of a positive force, pull the wire in the axial direction toward the wire, and the maintenance of 1min. The temperature experiment is to test terminals in normal use, the measuring instruments and other liquid level instrument by the acceptance of its temperature rise can not go beyond the rules of value, individual UL specification rules terminals in the electricity passed through it, the lower temperature can not exceed 30 ° C ambient temperature. The electrical properties experiment is to test the screw-type terminals in normal use, the electrical properties of the solid nature.

The mechanical strength of the experiment goal is to test terminal block whether there is sufficient mechanical strength, so the test terminal is very important.
