EN 60068-2-64-3 Vibration Endurance of Materials
The EN 60068-2-64-3 standard, part of the series on environmental conditions for electrical and electronic equipment, specifies methods to determine the vibration endurance of materials. This test is crucial in ensuring that components used in various industries can withstand the dynamic loads they may encounter during operation.
During this test, specimens are subjected to controlled vibratory loading under specified conditions. The purpose is to evaluate how well the material or component can maintain its performance and integrity over time without failure. This is particularly important for materials used in building structures, infrastructure projects, and electronic devices that may be exposed to environmental vibrations.
The test setup typically includes a vibration testing machine capable of generating controlled sinusoidal or random vibration inputs within the frequency range specified by the standard. The specimen must be properly clamped into the fixture to ensure it undergoes the prescribed loading conditions accurately. The test duration can vary based on the requirements set out in the specification, but it often involves sustained exposure to the defined vibratory environment for several hours.
Once testing is complete, detailed measurements are taken to assess any changes or degradation of the specimen’s properties, such as mechanical strength, electrical resistance, and dimensional stability. Reporting these results allows stakeholders to make informed decisions about material suitability and reliability.
| Parameter | Description |
|---|---|
| Vibration Frequency Range | 10 Hz to 500 Hz (or as specified by the standard) |
| Vibration Amplitude | 2 g peak-to-peak or other values specified in the test plan |
| Durational Exposure Time | Duration can vary based on material type and application, typically 10 to 50 hours |
The standard also provides guidance on specimen preparation, including dimensions, surface finish, and the method of clamping. Proper preparation ensures accurate test results by minimizing extraneous variables that could affect outcome.
- Material Types Tested: Plastics, metals, composites, electronic components
- Purpose of Testing: To ensure durability under environmental conditions

International Acceptance and Recognition
The EN 60068-2-64-3 standard is recognized globally for its rigorous approach to evaluating materials under vibration conditions. It has been adopted by numerous international organizations, including the International Organization for Standardization (ISO), providing a consistent framework for testing across different regions.
Many countries use this standard as part of their national standards and regulations. For instance, European Union directives often reference EN standards due to their stringent quality control measures. Similarly, in North America, industry consortia incorporate these standards into their product development processes to ensure compliance with international best practices.
Environmental and Sustainability Contributions
- Evaluating materials for sustainability: By ensuring durability under environmental conditions, this test helps in selecting sustainable materials that last longer, reducing waste.
- Reducing material usage: Longer-lasting components mean less frequent replacements, which can lead to reduced resource consumption and lower carbon footprints.
The use of EN 60068-2-64-3 contributes significantly to sustainable building practices by enhancing the longevity and reliability of materials used in infrastructure projects. This not only supports environmental goals but also promotes economic efficiency through reduced maintenance costs over time.
