Performance Requirements for R-134a and R-1234yf Refrigerant Diagnostic Identifiers for Use with Mobile Air Conditioning Systems

SAE J 2912-2011 发布历史

This SAE Standard applies to refrigerant identification equipment to be used for identifying refrigerant HFC-134a (R-134a) and/or 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 or other refrigerants are the option of the equipment manufacturer, although it shall not misidentify refrigerants. 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. The identifier also shall identify and display volume of non-condensable gases, such as air. The displays shall be in percentages and to the specified accuracies.
