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
SAE J2970-2015由SAE - SAE International 发布于 2015-03-01,并于 2015-03-19 实施。
