- Issuing Committee
- Content
- 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.
- Content
- 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.
