Glossary

It is the most widely used, robust and economical measurement method on the market. It involves the use of a single pressure sensor that directly measures pressure decay over time.

The limit within which a part is considered “good”. It must be defined based on its actual use: safety, functionality, industry standards.

Periodic verification that ensures the equipment measures correctly over time. For ForTest, this is a natural extension of the product: measurement certainty doesn’t end with the purchase.

The language through which the air leak tester communicates with the test bench or production line. It enables complete test automation.

It compares the pressure of the test piece with an identical reference chamber. It’s like a pressure “balance scale”.

Proprietary ForTest technology that combines the simplicity of absolute decay with the precision of differential. Dramatically increases measurement sensitivity without the limitations of traditional differential technology.

When the tester signals a nonexistent leak. This can be due to defective seals, vibrations, mismatched parts, or non-optimized parameters.

The flow test measures the amount of gas that passes through a component or a more complex system within a certain time interval.

Numerical value that expresses the actual leakage of the part. Often converted to standards such as sccm, ml/min or Pa·m³/s. It allows for objective comparison of different products.

Leak testing is a verification of the tightness of a component or more complex systems, necessary to ensure that there are no gas or fluid leaks.

Guarantee that the measurement is linked to international standards through certified calibration processes. It is the foundation of ISO quality.

Internal space that must be pressurized during the test. The larger it is, the more time and sensitivity the test requires. It is one of the decisive parameters for choosing the testing technology.

Fixtures, clamps, or devices that seal the part during testing. They are crucial: a good seal can make the difference between a stable test and an unpredictable one.

Time required for the part to reach an equilibrium condition before measurement. Incorrect stabilization is one of the main causes of false rejects.

Complete sequence of pressurization, stabilization and measurement that determines the leak tightness of the part. Optimizing it means reducing time without sacrificing precision.
