Lecktest
Lecktest, literally meaning "leak test" in German, designates a non-destructive testing method used to determine whether a closed system, component, or container exhibits leaks or can withstand a specified leak rate. The test typically involves applying a reference pressure or vacuum, then monitoring for a pressure drop, a rise, or the appearance of escaping gas or liquid. Detection can be accomplished directly via sensors, acoustics, or visual observation, and may also use tracer gases or liquids to locate leaks.
Common methods include pressure decay, where a known pressure is applied and the time-dependent pressure change
Applications of Lecktest span many industries, including automotive and aerospace for fuel, cooling, and hydraulic systems;
Practical considerations include selecting an appropriate method for the expected leak rate, ensuring proper calibration and
