Standard Test Methods for Leaks Using the Mass Spectrometer Leak Detector in the Detector Probe Mode
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 These test methods cover procedures for testing and locating the sources of gas leaking at the rate of 4.5 X 10 -13 mol/s (1 X 10 -8 Std cm3 /s) or greater. The test may be conducted on any device or component across which a pressure differential of helium or other suitable tracer gas may be created, and on which the effluent side of the leak to be tested is accessible for probing with the mass spectrometer sampling probe.
1.2 Two test methods are described:
1.2.1 Test Method A -Direct probing, and
1.2.2 Test Method B -Accumulation.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
