EN 60068-2-6-3 Vibration Test for Electrical Components
The EN 60068-2-6-3 vibration test is a critical procedure used to evaluate the durability and reliability of electrical components under dynamic loads. This standard, part of the larger series of environmental testing standards, specifies a method to determine the ability of electronic equipment to withstand mechanical shock and vibrations that may be encountered during transportation or operation.
The primary goal of this test is to ensure that electrical components maintain their functionality and integrity after being exposed to specified levels of vibration. The test setup involves placing the component on a shaker table, which delivers controlled sinusoidal or random vibration inputs according to predefined parameters.
Understanding the environmental conditions in which the product will be used is essential for setting appropriate test parameters. Factors such as altitude, humidity, and temperature can influence the severity of vibrations that the components might experience during transportation or operation. For instance, components intended for use in high-altitude areas may require more robust testing to account for reduced atmospheric pressure.
The standard specifies a range of vibration frequencies (typically from 10 Hz to 2 kHz) and amplitudes (measured in g-force levels), which can vary based on the type of electrical component being tested. The test duration is also critical, as it determines how long the component must endure the specified conditions without failing.
Specimen preparation plays a crucial role in this testing process. Components need to be secured properly to prevent movement during the test, which could lead to erroneous results. Proper clamping and positioning ensure that only the intended stresses are applied to the component being tested.
Instrumentation is vital for accurately measuring the vibrations imparted to the components and monitoring their responses. Sensors such as accelerometers provide precise data on the magnitude and frequency of the vibrations, allowing for real-time adjustments if necessary. These sensors must be calibrated regularly to maintain accuracy.
Reporting the results of the test is equally important. The report should include details about the test setup, including the type of shaker table used, the frequency range and amplitude levels applied, the duration of exposure, and any observed effects on the component’s performance. Compliance with these standards can help manufacturers ensure that their products meet quality expectations and are suitable for intended applications.

Applied Standards
The EN 60068-2-6 standard is widely recognized for its comprehensive approach to vibration testing. It specifies the procedures and requirements for conducting tests on various types of electrical components, ensuring that they can withstand the rigors of transportation and operational environments.
This standard is particularly useful in industries where reliability under environmental stress is paramount, such as aerospace, automotive, and telecommunications sectors. By adhering to these standards, manufacturers can demonstrate compliance with international quality and safety requirements, thereby enhancing their products' marketability.
Industry Applications
The EN 60068-2-6-3 vibration test finds extensive application across several industries due to its ability to simulate real-world conditions accurately. Aerospace manufacturers, for example, use this test to ensure that avionics and other electronic systems can withstand the vibrations encountered during takeoff and landing.
In the automotive industry, similar tests are conducted to verify the durability of onboard electronics against road noise and vehicle acceleration shocks. Similarly, telecommunications equipment manufacturers rely on these tests to guarantee that their products operate reliably in diverse environments.
By incorporating EN 60068-2-6-3 into their quality assurance processes, companies can significantly enhance their product robustness, thereby reducing the likelihood of failures during use. This not only improves customer satisfaction but also contributes to cost savings by minimizing warranty claims and repair costs.
