4.5 Test methods
The test method is chosen depending on the part to be tested. For more information about leak detec-
tion test methods, see Leak detector compendium on the www.pfeiffer-vacuum.com website.
4.5.1 Hard vacuum test
●Part that can be connected to pipe and placed under a vacuum
●Part that can be placed in a vacuum chamber
Spray method
This method involves removing the air from the part to be tested, connecting it to the detector's analyzer
cell, then spraying tracer gas on the points of the part that are likely to leak.
The detector measures the flow of tracer gas that penetrates due to part leakage.
When spraying starts, the leak rate is not displayed instantaneously: there is a response time which de-
pends on the volume V being tested and the tracer gas pumping speed S of the system at the inlet of
the part, according to the following relation:
●T = V/S (where T = seconds, V = liters, S = l/s).
●T is the time required for the leak rate to reach 63% of the final value.
Bombing method
The part is placed ahead of time in a pressurized gas tracer chamber. The tracer gas penetrates the
part through the potential leaks.
Then the part is removed from the chamber and placed in another vacuum chamber and connected to
the detector.
The detector measures the flow of tracer gas that leaks out of the part.
4.5.2 Sniffer test
●Part that can be connected to pipe and cannot be placed under a vacuum.
The part to be tested is pressurized with tracer gas.
The detector measures the flow of tracer gas that leaks out of the part through a sniffer probe that
moves across all the points prone to leaking.
The detector measures the flow of tracer gas that leaks out of the part.
The measured leak rate is not an exact measurement of the leak. The sniffer probe only detects part of
the tracer gas escaping from the part, depending on the distance separating the crack from the tip of the
probe, and the direction of the leak in relation to the probe.
