Druckanstiegsprüfung

Druckanstiegsprüfung is a German term that translates to "pressure rise test" or "pressure buildup test." It is a common method used in engineering and industrial settings to assess the integrity and leak-tightness of a system, component, or vessel. The fundamental principle involves introducing a pressurized gas into the system and monitoring the rate at which its pressure increases over a defined period.

This test is typically performed after a system has been sealed or repaired. If the system is perfectly sealed, the pressure will remain constant or rise only slightly due to temperature fluctuations. A significant or rapid pressure rise indicates the presence of leaks. The rate of pressure increase is directly proportional to the volume of gas leaking into the system from the surrounding atmosphere, or conversely, the rate of pressure decrease if the test is conducted by evacuating the system and monitoring its repressurization.

Druckanstiegsprüfung is widely applied in various industries, including automotive, aerospace, and manufacturing. It is crucial for ensuring the safety and reliability of products such as fuel tanks, pneumatic systems, and hydraulic circuits. The test parameters, such as the initial pressure, duration, and acceptable pressure rise limits, are usually defined by specific industry standards or product specifications. Analyzing the pressure-time curve allows for the detection and localization of leaks, facilitating timely repairs and preventing potential failures.
