Drop test simulates two situations: one is improper handling of packages during shipping and transportation, and the other is accidental dropping of unpackaged hand held products.
Usually the drop height is based on the weight and the drop probability. However, for the same weight, there is a variance of specified height in different international standards.
Most predetermined drop heights for hand held products (eg: cell phones, tablets, etc.) are between 100 cm to 150 cm. In IEC standards, hand held products ≦2 Kg are recommended a drop height of 100 cm without being damaged. In MIL standards, the drop height is 122 cm. Intel recommends the drop height to be 150 cm.
