Minimum Performance Requirements for Non-Refrigerant Tracer Gasses and Electronic Tracer Gas Leak Detectors

Scope
This standard provides the testing and functional requirements guidance necessary for a leak detection device that uses any non-A/C refrigerant tracer gas, such as helium or a nitrogen-hydrogen blend, to provide functional performance equivalent to a refrigerant electronic leak detector. It explains how a non- refrigerant leak detector’s calibration can be established to provide levels of detection equal to electronic leak detectors that meet SAE J2791 for R-134a and SAE J2913 for R-1234yf.
Rationale
Loss of refrigerant from leaking systems occurs when a system is charged to enable use of an electronic refrigerant leak detector or trace dye. Although a system can be checked with an electronic detector with as little as 10-15% of the specified charge installed in the system, trace dyes if not previously installed require a full refrigerant charge. As a result, use of any refrigerant as a fluid medium for leak detection is subject to regulation and an environmentally benign alternative may be required. Some manufacturers have proposed using a nitrogen/hydrogen blend as a trace gas for use in leak detection of mobile air conditioning systems. This standard is meant to define the minimum requirements for safety and performance of all non-refrigerant leak-tracer gasses.

Issuing Committee
Interior Climate Control Service Committee
The Interior Climate Control Service Committee is responsible for developing and maintaining SAE Standards, Recommended Practices, and Information Reports that serve as guidelines for technicians who service mobile air conditioning systems and operate refrigerant recycling equipment as it applies to automobiles, light trucks and other vehicles with similar R12 systems. Participants in the SAE Interior Climate Control Standards Committee include OEMs, suppliers, consulting firms, government, and other interested parties.

listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
