What is IEC 60068-2-31 free fall procedure?

IEC 60068-2-31 is a standard established by the International Electrotechnical Commission (IEC) that specifies a free fall procedure for testing the robustness of equipment and materials against mechanical shocks. In this article, we will delve into the details of this procedure, its significance, and how it is carried out.

The Purpose of IEC 60068-2-31 free fall procedure

The main purpose of the IEC 60068-2-31 free fall procedure is to evaluate the ability of an object or material to withstand mechanical shock caused by dropping it onto a hard surface. This procedure simulates real-life scenarios where objects may accidentally fall or be subjected to impact during transportation, handling, or usage.

By subjecting devices and materials to controlled free fall tests, manufacturers can assess their durability, identify potential weaknesses, and make necessary design improvements. This helps in ensuring that products are safe and reliable, as well as meeting regulatory requirements and customer expectations.

Procedure

The IEC 60068-2-31 standard outlines the specific steps to conduct the free fall procedure. Here is an of the procedure:

The test sample or object is positioned in its normal operating orientation.

The sample is securely mounted on a suitable platform or support structure.

The sample is dropped from a predetermined height onto a solid, rigid, and horizontal surface. The height is determined based on the mass and fragility of the sample.

Multiple drops are conducted from different orientations, typically six different faces of a cube-shaped sample.

After each drop, the sample is inspected for any visible damage or functional impairment.

The test results are recorded, including the number of drops and any observed anomalies or failures.

Conclusion

The IEC 60068-2-31 free fall procedure plays a vital role in ensuring the reliability and robustness of equipment and materials. By subjecting them to controlled mechanical shocks, manufacturers can evaluate their resistance to accidental drops and impacts. This procedure helps in enhancing the quality and durability of products, thereby contributing to customer satisfaction and safety standards.
