MET supplies equipment and services to test to ISO 10648-2: containment enclosures - part two: classification according to leak tightness and associated checking methods.
Typically, pressure decay measurements are used for assessing the leak rates of containment enclosures, and helium is used as a trace gas for the detection of leak location.
The large volume of a chamber and flexibility of its components, such as gloves, can pose challenges for the pressure decay test.
Similarly, temperature changes can have a significant effect on results.
MET said hydrogen testing can provide a useful alternative for the quantitative measurement and location of leaks.
MET can apply the H2000 leak tester to safely and accurately test chambers finding leaks in awkward locations.
