Mail-order package drop testing is a method used to evaluate the ability of mail-order product packaging to withstand impact during transportation. Here is an overview of the process:

Objective:
To simulate the potential drop scenarios that mail-order packages may encounter during actual transportation, and to test the packaging's protective performance. This ensures that the product remains intact and functional after experiencing impact, thereby guaranteeing the quality of the product received by consumers.

Standards:
International Standards: These include a series of standards set by organizations like the International Safe Transit Association (ISTA). For example, ISTA 1A and 2A provide detailed guidelines on drop testing methods and requirements for different types and weights of mail-order packages. ISTA 1A applies to single packages weighing up to 150 pounds (about 68 kilograms) for random vibration and drop tests.

National Standards: In China, there are relevant standards such as GB/T 4857.5, which outlines the free fall test methods for transport packages. This standard specifies the purpose, equipment, procedures, and other details of the test, providing specific operational guidelines for mail-order package drop testing.

Testing Method:
Preparation: First, check if the test sample's packaging is intact and sealed properly, and ensure the product is correctly placed inside. Record the weight, dimensions, and other information of the package.

Select Drop Height: Based on the package's weight and product characteristics, choose an appropriate drop height according to relevant standards. Generally, lighter small packages may have a drop height between 0.8 meters and 1.2 meters, while heavier large packages might have a lower drop height around 0.5 meters to 0.8 meters.

Determine Drop Direction: Typically, this includes corner drops, edge drops, and face drops. A corner drop involves one corner of the package hitting the ground, simulating the most unfavorable impact during handling or transportation. An edge drop involves one edge of the package touching the ground, and a face drop involves one flat surface of the package landing. Each direction usually requires multiple drop tests to comprehensively assess the package's impact resistance.

Conduct Drop Test: Use professional drop testing equipment, such as a drop tester, to lift the package to the specified drop height and then release it to fall freely onto the designated impact surface. Ensure the package is not interfered with during the fall to maintain the accuracy of the test results.

Inspection and Evaluation: After the drop test, carefully inspect the package for any damage, deformation, and check if the product has been damaged or shifted. For fragile or easily damaged products, further functional tests may be required, such as checking if electronic devices can power on and operate normally, or if mechanical parts are loose and can function properly. Evaluate the protective performance of the packaging based on the inspection results to determine if it meets the required standards.
