This test is usually mainly used to simulate the free fall that unpackaged/packaged products may experience during handling, and to investigate the ability of the product to withstand unexpected shocks. Usually the drop height is mostly based on the weight of the product and the possible drop probability as a reference standard. The falling surface should be a smooth, hard and 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 standards, even if the product is of the same weight, the drop height is different. For handheld products (such as mobile phones, MP3, etc.), most of the drop heights range from 100cm to 150cm. IEC applies to handheld models ≦2kg. It is recommended that the product should meet a drop height of 100cm and not be damaged, MIL recommends a drop height of 122cm, and Intel recommends a drop height of 150cm for handheld products (such as mobile phones). The severity of the test depends on the height of the drop, the number of drops, and the direction of the drop.
