Abstract

A leak test apparatus that includes a test chamber, a pressure transducer, a vacuum source, and a vapor trap. The test chamber may be configured to receive a test part and the pressure transducer may be coupled in fluidic communication to the test chamber. The vacuum source and the vapor trap may be coupled in fluidic communication to the test chamber. The vacuum source may be configured to draw a vacuum on the test chamber and the vapor trap may be configured to mitigate vapor off-gassing. A method for leak testing includes positioning a test part in a test chamber, evacuating the test chamber to a vacuum pressure with a vacuum source, mitigating vapor off-gassing with a vapor trap, and detecting a pressure rise in the test chamber.
