Drop test
Project Introduction
The drop test is divided into packaged drop and bare metal drop. Package drop mainly considers the product's ability to withstand accidental drops during transportation and storage; bare metal drop mainly considers the product's ability to withstand accidental drops during normal use. Packaging drop can also reflect the ability of the package to protect the product when it is vertically dropped.

The drop height, number of drops, and direction of drops reflect the rigor of the test. International standards for different products have different requirements for drop methods and drop heights. For handheld products (such as mobile phones, MP3 players, etc.), most drop heights range from 100cm to 150cm. IEC recommends that handheld products ≦2kg should meet a drop height of 100cm without being damaged, while MIL recommends a drop height of is 122cm. Intel recommends a drop height of 150cm for handheld products (such as mobile phones).

According to the reference standard, the drop surface is a smooth, hard rigid surface made of concrete or steel, or other floors, such as marble floors, if necessary.

The general requirements for packaging drop testing are that the drop method is a free fall from one corner, three sides, and six sides.

Corner drop: After falling, the test corner hits the contact plane;

Edge drop: tilt the bottom surface of the sample to a horizontal angle of 20°, then raise it to the test height and then drop it, and its edge hits the contact plane;

Surface drop: The test sample needs to be dropped and its flat surface directly hits the contact surface.

Packaging drop test determines whether the strength of the outer box or inner box and the firmness of the product packaging meet quality requirements.

The purpose of bare metal drop testing

The bare metal drop test is to test the product's ability to resist being thrown and dropped during use. The method of releasing the test sample should allow the test sample to fall freely from the suspended position and minimize disturbance when releasing.


· ASTM standard test instrument requirements: The throwing ground must be covered with a 3.0mm (1/8in) thick rubber floor, at least 64mm (2.5in) thick concrete, and the area must be no less than 3㎡.

· EN71 standard test instrument requirements: The throwing ground is paved with a 4mm thick steel plate. The surface of the steel plate should be coated with a 2mm thick covering layer with a Shore hardness of 75±5A and placed on a non-flexible horizontal surface.

· GB6675 standard test instrument requirements: The impact surface should be composed of a vinyl polymer sheet with a rated thickness of about 3mm. The vinyl polymer sheet is attached to concrete at least 64mm thick. The cover surface should reach Shore A80 degrees ±10 degree, with an area of at least 0.3㎡.
