A tracer-gas leak testing method is a nondestructive testing method that detects gas leaks.A variety of methods with different sensitivities exist. Tracer-gas leak testing is used in the petrochemical industry, the automotive industry, the construction industry [1] and in the manufacture of semiconductors, among other uses.
Methods of detection include hydrostatic testing, tracer-gas leak testing, infrared, laser technology, and acoustic or sonar technologies. Some technologies are used only during initial pipeline installation and commissioning, while other technologies can be used for continuous monitoring during service.

In contrast to the Helium charged sniffer test, the partial vacuum method, the ultra sniffer test gas method (UST-method) uses the partial vacuum effect, so that the gas tightness of test sample can be detected at normal pressure with the same sensitivity as the helium charged vacuum test with helium gas helium. The method has a sensitivity of ...
