What is IEC 60068-2-31 Freefall Procedure?

IEC 60068-2-31 is a standard defined by the International Electrotechnical Commission (IEC) that specifies a method for testing the resistance of equipment to freefall impacts. This procedure helps determine the ability of devices to withstand shocks experienced during transportation and handling.

How does it work?

The IEC 60068-2-31 freefall procedure involves subjecting the test sample to controlled drops from specific heights onto different surfaces. The purpose is to replicate the impact forces that may occur during accidents or mishandling. These drops are performed along with other environmental tests to assess a product's overall durability and reliability.

Testing parameters and requirements

When conducting the IEC 60068-2-31 freefall test, several parameters need to be considered:

Drop heights: The test requires selecting appropriate drop heights based on the characteristics of the device and its expected use. For example, handheld electronic devices may undergo drops from lower heights, while larger equipment may be subjected to higher drops.

Drop surface: Different surfaces, such as hardwood, concrete, or carpet, can be chosen to simulate various real-world scenarios.

Number of drops: The standard specifies the number of drops required for different types of products, which typically range from a few drops to several dozen.

Interpreting test results

After completing the freefall test according to IEC 60068-2-31, the test sample is carefully inspected for any visible damage or malfunctions. The evaluation also includes functional tests to ensure that the device still operates as intended. Based on the results, manufacturers can identify weaknesses and make design improvements to enhance their product's durability.

The IEC 60068-2-31 freefall procedure provides a standardized way to assess a product's resilience to impacts. By conducting these tests, manufacturers can meet quality standards and deliver reliable devices that can withstand real-world handling and transportation conditions.
