The impact test device with a steel ball can meet the requirements of IEC60598-1, IEC60950-1 clause 4.2.5 and AS-NZS61439.4 clause 10.2.6.2. It is applied to do the drop impact test for external surface of enclosure. The device can do vertical free fall impact and horizontal pendulum impact, the impact height can be adjustable as per the specimen, electromagnetic release the ball to make it fall freely, hit the sample, and judge the quality according to the degree of damage, it has the features of easy operation and high accuracy.
A sample consisting of complete enclosure is supported in its normal position, a solid smooth steel ball with 50mm diameter and 500g±25g mass is permitted to fall freely from rest through a vertical distance of 1.3m onto the sample. In addition, the steel ball is suspended by a cord and swung as pendulum in order to apply a horizontal impact, dropping through a vertical distance of 1.3m onto the sample. Alternatively, the sample is rotated 90 degrees about each of its horizontal axes and the ball dropped as in the vertical impact test. the impact test is applied to the face of a cathode ray tube, the platen glass of equipment, the surface of enclosure of stationary equipment and a flat panel display.
