Scope
This SAE Standard applies to refrigerant identification equipment to be used for identifying refrigerant HFC-134a (R-134a) and HFO-1234yf (R-1234yf) refrigerant when servicing a mobile A/C system or for identifying refrigerant in a container to be used to charge a mobile A/C system. Identification of other refrigerants is the option of the equipment manufacturer, although it shall not misidentify refrigerants, per 3.2.
Rationale
This standard is being updated to include USB communication protocol required for use with SAE J3030 certified equipment when configured for use with R134a. Two of the mixture tests, incorporating R-1243zf are deleted to enhance identifier performance by eliminating testing for a fluid with no known potential for mobile A/C application as a refrigerant at this time.

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.

* Redlines comparisons are available for those standards
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.
