Performance Requirements for R-134a and R-1234yf Refrigerant Diagnostic Identifiers (RDI) for Use with Mobile Air Conditioning Systems
- Ground Vehicle Standard
Published December 11, 2014 by SAE International in United States
Downloadable datasets availableAnnotation ability available
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.
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.

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.
