    Withdrawn Rationale:

    Formerly under the jurisdiction of Committee F01 on Electronics, this test method was withdrawn in June 2008 in accordance with section of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

    1. Scope

    1.1 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.

    1.2 Leak detector parameters determined by this test method include:

    1.2.1 Minimum detectable signal, drift noise (8.5, with recorder; 8.6, without recorder),

    1.2.2 Response time,

    1.2.3 Minimum detectable leak rate, and

    1.2.4 Sensitivity.

    1.3 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.
