Drop Test

This test is usually used to simulate the free fall of unpackaged/unpackaged products during handling and to investigate the product's ability to withstand unexpected shocks. Usually the drop height is based on the weight of the product and the possible drop probability. The falling surface is a smooth, rigid surface made of concrete or steel (if there are special requirements, it should be determined by product specifications or customer test specifications).

For different international specifications, the drop height is different even if the product is under the same weight. For the product of mechanism type (e.g. 2.5 inch/1.8 inch shell), the drop height mostly ranges from 100 cm to 150 cm. For the handheld product of less than 2 kg, IEC suggests that the drop height of 100 cm should not be damaged. MIL suggests that the drop height should be 122 cm. For most of the large-scale product of mechanism, the drop height should be tested. The height is 150 cm. The severity of the test depends on the height, frequency and direction of the fall.
