What is drop test?

 Drop testing is usually used to simulate the free drop that a product may suffer during handling, examining the ability of the product to withstand accidental shocks. The drop height is usually based on the weight of the product, and the probability of falling, as a reference standard, and the drop surface should be a smooth, hard, rigid surface made of concrete or steel.

For different international specification even if the product under the same weight but the drop height is not the same, for the handheld products (such as mobile phones, MP3, etc.) most drop height between 100cm ~ 150cm, IEC for 2kg handheld products recommendations should meet 100cm drop height is not damaged, MIL is recommended drop height is 122cm, Intel for handheld products (such as mobile phone) recommendations drop height is 150cm.

The severity of the test depends on the height, number and direction.
