Package drop test method

Test principle

Lift the test sample to the predetermined height, then let it fall freely according to the predetermined state and collide with the impact table.

Test procedure

1 Lift the test sample to the desired drop height position and support it to the difference between the lift height and the predetermined height as it is.

No more than 2% of the predetermined height of the taxi. The drop height refers to the deviation between the lowest point of the test sample and the impact table when ready to release.

2 Release the test sample according to the following predetermined conditions:

a. When the surface falls, the angle between the falling surface of the test sample and the horizontal plane is not more than 20;

b. When the edge falls, the angle between the falling edge and the horizontal plane is not more than 2', and the specified surface and the impact table are clamped on the test sample.

The error of the angle is not more than ±5. Or 10% of the angle (whichever is greater), so that the gravity line of the test sample passes through the edge that is dropped;

c When the angle falls, the angle between the specified surface and the impact table on the test sample is not more than ±5. Or this angle of 10, y (to a larger

The value is based on the angle at which the gravity line of the test sample passes through the drop;

d Regardless of the state and shape of the test sample, the gravity line of the test sample shall pass through the fallen face, line, and point.

3 The difference between the actual impact speed and the impact speed at the time of free fall does not exceed 1% of the taxi at the time of free fall.

4 After the test, check the damage of the package and contents according to the relevant standards or regulations. And analyze the test results.

Test equipment

The drop tester is a machine designed to test the damage of the product package from falling and to evaluate the impact strength during transport handling. It adopts double-column guidance and can set the height drop number. It is stable and reliable, and can achieve edge, surface and corner drop, and meet GB/T4857.5-92 and ISO2248-1972E. Drop test machine classification: Single-column drop test machine, double-column drop test machine,zero drop test machine.
