What is IEC 60068-2-27?

IEC 60068-2-27 is an international standard that addresses the environmental testing of electrical and electronic equipment. It specifies a test method for determining the ability of equipment to withstand mechanical shock, specifically in terms of its functional performance. This test method is widely used in various industries to ensure product reliability and quality.

The Purpose of IEC 60068-2-27

The primary purpose of IEC 60068-2-27 is to simulate the effects of mechanical shocks that equipment may encounter during transportation, installation, or operation. By subjecting the equipment to controlled shock impulses, manufacturers can assess its ability to continue functioning properly without suffering any damage or malfunction. It helps determine whether the equipment can withstand impacts such as drops, falls, or sudden jolts without affecting its usability or safety.

Testing Procedure

The testing procedure outlined in IEC 60068-2-27 involves subjecting the equipment to well-defined shock pulses or acceleration levels. The equipment is mounted on a rigid base and exposed to a series of half-sine shock pulses with predefined durations and amplitudes. These shock pulses are generated by an impactor or a shock machine.

During the test, the equipment's functional performance is continuously monitored to ensure that it continues to operate within specified parameters. Any deviation from the specified performance criteria can indicate potential weaknesses in the design or manufacturing process.

Benefits and Applications

Compliance with IEC 60068-2-27 provides several benefits for manufacturers and end-users. Firstly, it helps manufacturers identify design flaws or weaknesses in their products and make necessary improvements before release. This can save time and costs associated with repairing or replacing faulty equipment.

End-users also benefit from this standard as it ensures that the purchased equipment has undergone rigorous testing and is reliable in terms of shock resistance. It provides a level of confidence in the equipment's ability to withstand mechanical stresses and perform consistently under normal operating conditions.

In conclusion, IEC 60068-2-27 plays a crucial role in assessing the mechanical robustness of electrical and electronic equipment. By subjecting products to controlled shock tests, manufacturers can ensure their equipment can endure shocks encountered during transportation, installation, or operation. Compliance with this standard leads to improved product quality, increased customer satisfaction, and reduced maintenance costs.
