Record number: 5, Textual support number: 1 DEF

A form of leak test in which the interior of an enclosure is actively evacuated while a tracer gas is applied to the exterior. The objective is to draw in some of the gas through possible leakage paths so that its presence becomes evident to a leak detector which will respond to the type of the type of gas used and which is connected in the evacuating system.  1, record 5, English, - dynamic%20leak%20test

A leak detecting device employing two similar Pirani tubes being connected to the system under test. A cold trap is placed between one tube and the system. Condensable tracer gas entering the system reaches one tube but not the other, thus unbalancing the bridge and indicating leakage.  1, record 6, English, - differential%20Pirani%20gauge

A testing method for sealed units in which units are subjected to a tracer gas pressure for a period, then the tracer gas is flushed from outside the unit, and the tracer gas leakage from the unit is measured.
