Abstract

This SAE Standard applies to refrigerant diagnostic 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.  Purpose  Establishing such specifications will ensure equipment that meets this standard can identify relatively pure refrigerant HFC-134a (R-134a) and HFO-1234yf (R-1234yf) from mixtures of refrigerants (HFC, HCFC, CFC, hydrocarbons, etc.) in a refrigerant supply tank or mobile system prior to recovering/recycling (R/R) the refrigerant or prior to charging an A/C system from a refrigerant container to meet SAE J2099 requirements. The identifier also shall identify and display weight of non-condensable gases, such as air. The displays shall be in percentages, per 3.1.3, and to the specified accuracies.
