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. The revisions in this document are to identify the requirements that shall be included for integration of an identifier for use with SAE J2843 Recovery/ recycle/ recharge equipment and the communication protocol that is required.
