SAE J2912-2020 PDF

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. 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 ecycling (R/R) the refrigerant or prior to charging an A/C system from a refrigerant container. 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.
