Scope:

This SAE Standard provides testing and functional requirements to meet specified minimum performance criteria for electronic HFC-134a probe-type leak detectors. So they will identify smaller refrigerant leaks when servicing all 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 their design or use.

Rationale:

The need to reduce HFC-134a emissions has led to improved designs of mobile air conditioning systems, including smaller refrigerant charges and tighter seals to better contain the smaller charges and minimize refrigerant emissions. 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, as indicated by original equipment manufacturers.
