Leak Testing Based on Overpressure Methods.

    • Overpressure Methods

The equipment to be tested is pressurized with a gas, search gas, or a search gas mixture. Between the two methods there exist many variations depending on the particular application.

    • Pressure Drop Method.

The test object is filled with a gas (for example air or nitrogen) until the testing pressure is reached. Precision gauges are used to detect a possible pressure drop during the testing period. This method is simple to implement, it is suitable for the determination of gross leaks and can be improved upon by using differential pressure gauges.
