Leak testing, or leak detection, is a process used to identify and quantify leaks in a sealed system. These systems can range from industrial pipelines and pressure vessels to consumer products like refrigerators and automotive components. The primary goal of leak testing is to ensure the integrity and functionality of a sealed system, preventing the loss of contained substances or the ingress of unwanted external elements.

Various methods are employed for leak testing, often depending on the nature of the system, the substance being contained, and the required sensitivity. Common techniques include pressure testing, vacuum testing, and tracer gas detection. Pressure testing involves pressurizing the system with a gas, such as air or nitrogen, and then monitoring for any pressure drop. Vacuum testing is the inverse, where a vacuum is created and the rate of pressure increase due to incoming air is measured. Tracer gas methods utilize a specific gas, like helium or hydrogen, introduced into or around the system. Sensitive detectors are then used to identify the presence of this tracer gas escaping from or entering the system.

The importance of leak testing cannot be overstated. In industrial settings, undetected leaks can lead to significant product loss, increased operational costs, environmental contamination, and safety hazards. For consumer products, leaks can compromise performance, reduce lifespan, and even pose safety risks. Therefore, rigorous leak testing is an essential part of quality control and product development across numerous industries.
