What is the limit of leak test?

Question

Accepted Answer

The detection limit of a leak test is the minimum leak which can be identified by a leak test system. This depends on the technique and equipment. In the case of helium leak testing, which is very sensitive, detection limits are extremely low, being around the size of a single hole diameter. Practically, the detection limit is affected by aspects such as test gas background level, system design, and calibration. For instance, the inherent helium content of air can restrict the detection capacity of certain methods. Highly sensitive leak detectors that use mass spectrometers can produce detection limits that are very low under optimum conditions, but to obtain reproducible measurements at such levels is demanding and calls for meticulous system design and calibration.The selection of the detection limit is based on the application and the precision needed. Detection limits are usually established in accordance with safety requirements and product standards in industrial applications, thereby ensuring products are up to quality and safety standards.
