DIN EN 60068-2-64 Vibration and Temperature Test
The DIN EN 60068-2-64 standard specifies the procedure for testing materials, components, assemblies, or complete units exposed to combinations of sinusoidal vibration and temperature cycling. This testing is essential in ensuring that HVAC equipment made from ferrous metals and alloys can withstand the environmental stresses they are likely to encounter during operation.
During this test, specimens undergo exposure to controlled cycles of mechanical vibration and thermal environments designed to simulate real-world conditions. The purpose is to identify any potential failures or degradation caused by these combined stressors before the equipment reaches its end-of-life stage.
The standard applies to a wide range of products including heat exchangers, condensers, evaporators, and other critical components in HVAC systems that are fabricated from ferrous metals like steel and iron. By adhering strictly to DIN EN 60068-2-64 requirements, manufacturers can ensure their products meet stringent quality standards.
The test setup typically involves placing the specimen inside an environmental chamber equipped with vibration excitation equipment capable of generating sinusoidal vibrations across a specified frequency range (usually between 10 Hz and 500 Hz). The temperature within the chamber is controlled to achieve predetermined cycles, which may vary depending on specific product requirements.
It's important to note that proper specimen preparation plays a crucial role in achieving accurate results. Specimens should be representative of actual production parts and free from defects such as cracks or loose fasteners that could affect test outcomes. Any necessary modifications must also follow strict guidelines outlined within the standard itself.
The testing procedure follows predefined cycles consisting of temperature transitions followed by vibration exposures. Each cycle consists of several stages: initial equilibration at room temperature, gradual heating up to maximum specified temperatures (which can exceed 100°C), cooling back down to ambient conditions before being subjected to low-frequency vibrations, then higher frequency vibrations.
After completing all required cycles, the specimen is inspected for signs of damage or performance degradation. Acceptance criteria are based on visual inspections and functional testing where applicable. If any defects are detected during inspection, further analysis may be necessary to determine root causes.
| Test Cycle | Temperature Range (°C) | Vibration Frequency Range (Hz) |
|---|---|---|
| Cycle 1 | -20 to +65°C | 10 to 50 Hz |
| Cycle 2 | -40 to +85°C | 30 to 100 Hz |
| Cycle 3 | -60 to +95°C | 50 to 200 Hz |
