Title
Standard Test Method for Calibration of Helium Leak Detectors by Use of Secondary Standards
ASTM International
Publication Date:
Dec 10, 1997
Scope:
This test method covers a procedure for calibrating a mass
spectrometer-type helium leak detector
with a series of commercially available calibrated leaks without need
for recourse to a primary
standard.
Leak detector parameters determined by this test method include:
Minimum detectable signal, drift noise (8.5, with recorder; 8.6,
without recorder),
Response time,
Minimum detectable leak rate, and
Sensitivity.
This standard does not purport to address 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.
Keywords:
- leak detection
- minimu leak rate
- vacuum devices
