Abstract
There is close correlation between the reliability of the launch vehicle and the leakage of the propellants or gases from the launch vehicle. This paper describes the definition of the leak rate to determine the quantity of the leakage and introduce the unit conversion of the leak rate. The main parameters for the leak rate were considered. The requirements for the gaseous for the leak test of launch vehicle and various leak test methods were introduced. Leak test method and procedure used in space launch vehicle were briefly described.
