Leak testing with tracer gas: Tracer gas is defined as “in the case of the vacuum method, gas that is sprayed onto the outer surface of the test piece to be leak tested and enters the test piece through the leaking point. In the case of pressure testing, it is introduced into the test piece to be gas that is detected after it is released from a leaking point to the outside.” In order to detect the gas, the difference in physical properties of the gas is used. Therefore, in this lecture, classification by detection method and representative leak test methods will be explained, and the latest trends in leak detectors will be introduced. Efforts of the leak testing (LT) department at the Japanese Society Non-Destructive Inspection: This section describes the JIS / NDIS standards related to the Leak testing (LT = Leak testing within the Association) category. Next, an overview of the activities of committees held at the Association and the leak testing certification system will be introduced.
