Standard Test Method for Calibration of Helium Leak Detectors by Use of Secondary Standards
|Publication Date:||10 December 1997|
|ICS Code (Semiconductor devices in general):||31.080.01|
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),
Minimum detectable leak rate, and
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.
