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. This standard is being updated to modify the requirements when the tracer gas is significantly lighter than air. The Contaminated Atmosphere test is not required for tracer gases with a molecular weight of 20 or lower. Tracer gases with a molecular weight of 20 or lower will diffuse rapidly into the ambient atmosphere and will therefore not be a contaminant.
