SAE J2913_201102

This SAE Standard provides testing and functional requirements to meet specified minimum performance criteria for electronic probe-type leak detectors. The equipment specified here will identify smaller refrigerant leaks when servicing motor vehicle air conditioning systems, including those engineered with improved sealing and smaller refrigerant charges to address environmental concerns and increase system efficiency. This document does not address any safety issues concerning the equipment design or use beyond that of sampling a flammable refrigerant save those described in 3.1 and 3.2 of this document. All requirements of this standard shall be verified in SAE J2911. The need to reduce R-1234yf emissions has led to improved designs of mobile air conditioning systems, including smaller refrigerant charges and tighter seals to better contain the smaller charges. That in turn has created the need for a generation of leak detectors capable of finding very small to moderate leaks, both to address environmental concerns for effective leak detection and repair in service, and to enhance customer satisfaction by identifying all leaks that are of repairable sizes.
