What is IEC 60068-2-75?

Introduction

IEC 60068-2-75 is an international standard that specifies the requirements and testing methods for mechanical shock and impact resistance of equipment. It is part of the IEC 60068 series, which covers environmental testing for various types of electrical and electronic products.

Scope and Purpose

The purpose of IEC 60068-2-75 is to ensure the reliability and performance of equipment when subjected to mechanical shock and impact. This standard defines the severity levels, test procedures, and evaluation criteria for assessing the ability of equipment to withstand such conditions.

IEC 60068-2-75 applies to a wide range of equipment types, including consumer electronics, industrial machinery, transportation vehicles, and medical devices. It is used by manufacturers, testing laboratories, and regulatory bodies to determine if equipment meets the required standards for mechanical robustness.

Testing Procedures

The testing procedures outlined in IEC 60068-2-75 involve subjecting the equipment to different levels of shocks and impacts. These levels are defined in terms of acceleration and duration. The standard provides guidance on how to calculate the required levels based on the equipment's mass, fragility, and intended use.

The tests are conducted using specialized machines that can deliver precise shocks, impacts, or repetitive blows to the equipment. The equipment under test is typically mounted on a vibration table or fixed to a rigid structure. The shocks and impacts are applied in multiple directions to simulate real-world scenarios.

Evaluation Criteria

After subjecting the equipment to the specified shocks and impacts, various parameters are measured and evaluated. These parameters may include functionality, structural integrity, electrical performance, and any visible damage.

The evaluation criteria specified in IEC 60068-2-75 help determine whether the equipment has passed or failed the test. The standard provides guidelines on what constitutes an acceptable level of performance based on the intended use of the equipment.

Conclusion

IEC 60068-2-75 plays a crucial role in ensuring the reliability and durability of equipment under mechanical shock and impact conditions. By following this standard, manufacturers can design and produce robust products that can withstand harsh environments and deliver consistent performance to end-users.

Overall, IEC 60068-2-75 is an essential tool for both manufacturers and consumers in evaluating the mechanical robustness of equipment and ensuring their long-term reliability.
