Lift the test sample to the desired drop height position and support it as intended. The difference between the straight-up height and the predetermined height must not exceed ± 2% of the predetermined height. The drop height is the distance between the lowest point and the impact table when the test sample is ready to be released.

Release the test sample according to the following predefined conditions

When the surface is dropped, the angle between the falling surface of the test sample and the horizontal surface should not exceed 2 °.

When the ribs fall, the included angle between the falling rib and the horizontal plane should not exceed 2 °. The error between the specified plane and the angle of the impact table on the test specimen should be no more than ± 5 ° or 10% of the included angle ( in larger values Quasi ) so that the gravity line of the test sample passes through the dropped test specimen of whatever state and shape, so that the heavy sample line of the test sample should pass through the dropped surface, line, and point

The difference between the actual impact speed and the impact speed at free fall is not more than 1% of the free fall.

After the test, check the damage of the packaging and contents according to relevant standards or regulations, and analyze the test results

Examples:

After a product is packaged, it may be dropped during the handling process. The impact caused by the product will damage the product. Therefore, general manufacturers will perform drop tests on the packaged product. The drop height problem is mainly determined by the weight of the product, but according to various standards, there may be different heights for the sample of the same weight. Therefore, we must be clear about which standard to use before testing. Here, I probably say something about the order of the fall.

The general drop test is carried out with a total of ten dips in three corners and six sides. Certainly there are some other criteria. There are also other provisions for the number of falls and the state of fall. I am here to talk about the conventional method of triangulation and six sides.

To get a sample, first number the sample.

Place the package properly, with one side at the top and three sides at the bottom. These two sides will not change at any time. Then, the smallest face of the carton joint is facing itself. The face is 5 faces and the opposite face is 6 faces. The larger surface of the carton joint is two surfaces and the opposite surface is four surfaces. In this way, a complete package will be identified. ( as shown below )

The drop order is:

Angle: 2-3-5 angle ;

Edge: The shortest edge next to the 2-3-5 angle, again long edge, and finally the longest edge ;

Noodles: 5 sides, 6 sides, 2 sides, 4 sides, 1 side, 3 sides.

In this way, the entire drop test is completed, of course, can also be slightly modified according to actual conditions or customer requirements, the number of falls is generally 1 times.
