Dichtungsprüfung

Dichtungsprüfung, also known as leak testing, is a crucial process in various industries to ensure the integrity and reliability of sealed components and systems. It involves methods and techniques designed to detect and quantify the presence of leaks, which are unintended passages through which fluids or gases can escape or enter.

The purpose of Dichtungsprüfung is to prevent product loss, contamination, safety hazards, and inefficient operation. In manufacturing, it's often a final quality control step for products like automotive parts, medical devices, and electronics. In infrastructure, it's used for pipelines, tanks, and building envelopes to maintain pressure and prevent environmental damage.

There are numerous methods for conducting Dichtungsprüfung, categorized by whether they are destructive or non-destructive. Common non-destructive techniques include pressure testing (using air, water, or inert gases), vacuum testing, bubble testing, and tracer gas detection. The choice of method depends on factors such as the size and type of the item being tested, the expected leak rate, the fluid or gas involved, and the required accuracy.

The results of a Dichtungsprüfung are typically reported as a pass or fail, or by quantifying the leak rate in units such as Pascal cubic meters per second (Pa m³/s) or standard cubic centimeters per minute (sccm). Identifying and repairing leaks is essential for product performance, environmental protection, and operational safety.
