Leckageprüfung

Leckageprüfung, also known as leak testing, is a non-destructive testing method used to detect and quantify leaks in enclosed or sealed systems. The primary goal is to ensure the integrity of a product or component by verifying that it does not allow unwanted passage of fluids or gases. This is crucial in many industries, including automotive, aerospace, medical device manufacturing, and packaging, to guarantee product safety, functionality, and efficiency.

There are various techniques employed for Leckageprüfung. One common method is pressure testing, where a system is pressurized with a gas and then monitored for pressure drops. Another approach involves vacuum testing, where a system is evacuated and then checked for an increase in internal pressure. For smaller leaks, tracer gas detection is often used, where a specific gas is introduced into or around the system and then detected using specialized sensors. Bubble testing is a simpler visual method where a component is submerged in a liquid, and the presence of bubbles indicates a leak.

The sensitivity of Leckageprüfung methods can vary significantly, allowing for the detection of very small leaks that might otherwise go unnoticed. The choice of method depends on factors such as the size and nature of the leak, the type of fluid or gas being contained, the product material, and the required level of accuracy. Accurate Leckageprüfung is essential for preventing product failures, environmental contamination, and potential safety hazards.
