The purpose of this SAE Recommended Practice is to provide equipment specifications for CFC-12 (R-12) recovery for return to a refrigerant reclamation facility that will process it to ARI standard 700-88 as a minimum (Air Conditioning and Refrigerant Institute). It is not acceptable that the refrigerant removed from a mobile air-conditioning system, with this equipment, be directly returned to a mobile air-conditioning system. This information applies to equipment used to service automobiles, light trucks, and other vehicles with similar R-12 systems.

The purpose of this SAE Standard is to provide equipment specifications for CFC-12 (R-12) recovery for return to a refrigerant reclamation facility that will process it to the appropriate ARI Standard (Air Conditioning and Refrigerant Institute) or allow for recycling of the recovered refrigerant in equipment that is certified to meet the requirements of SAE J1991. Under the existing rule, the U.S. EPA requires refrigerant removed from a mobile air-conditioning (A/C) system using recovery equipment certified to meet SAE J2209 can only be recycled using equipment meeting SAE J1991 that is owned by the same company or individual. It is not acceptable that the refrigerant removed from a mobile A/C system, with this equipment, be directly returned to a mobile A/C system. This information applies to equipment used to service automobiles, light trucks, and other vehicles with similar CFC-12 (R-12) systems.

The purpose of this document is to provide equipment specifications for CFC-12 (R-12) recycling and/or recovery, and recharging systems. This information applies to equipment used to service automobiles, light trucks, and other vehicles with similar CFC-12 systems.

The scope of this SAE Recommended Practice is to establish uniform test procedures for passenger cars, to determine whether the system is defined as a defroster or defogger, and to establish minimum performance requirements for each system. A defroster for purposes of this practice is a system which will remove moisture and/or frost from the interior surface of the backlight at −18 °C. A defogger is a system which will remove moisture and/or fog from the interior surface of the backlight at 4 °C. The test procedure is intended to simulate actual conditions by utilizing either a cold room with an appropriate device to introduce air flow over the backlight or a sufficiently large wind tunnel with ambient temperature control. The test procedure and the minimum performance requirements are based on currently available engineering data.

The scope of this SAE Recommended Practice is to establish uniform test procedures for passenger cars, to determine whether the system is defined as a defroster or defogger, and to establish minimum performance requirements for each system. A defroster for purposes of this practice is a system which will remove moisture and/or frost from the interior surface of the backlight at 0°F (−18°C). A defogger is a system which will remove moisture and/or fog from the interior surface of the backlight at 40°F (4°C). The test procedure is intended to simulate actual conditions by utilizing either a cold room with an appropriate device to introduce air flow over the backlight or a sufficiently large wind tunnel with ambient temperature control. The test procedure and the minimum performance requirements are based on currently available engineering data.

This SAE Standard applies to electronic probe-type leak detectors used to service motor vehicle passenger compartment air-conditioning systems. This document does not address any safety issues concerning their design or use.

The purpose of this SAE Recommended Practice is to provide a service procedure for retrofitting a CFC-12 (R-12) system to HFC-134a (R-134a) while preserving performance and integrity of the air-conditioning (A/C) system. The steps outlined in this procedure are complete when combined with good service practices and the vehicle manufacturer's recommendations (if available) for retrofitting their models. Separate service equipment, for CFC-12 (R-12) and HFC-134a (R-134a), including refrigerant recovery/recycle (R/R), service manifolds, vacuum pumps, and charging equipment shall be used to preserve the purity of the refrigerants and the mobile A/C systems. This procedure will minimize release of refrigerant to the atmosphere, and will preserve the integrity of the recycled CFC-12 (R-12) and HFC-134a (R-134a) supplies. This document applies to A/C systems used to cool the passenger compartment of automobiles, light trucks, and other vehicles with similar CFC-12 (R-12) systems.

This SAE Standard provides manufacturers, testing facilities and providers of technician training with a procedure for certifying compliance with the appropriate standards. Manufacturers who advertise their products as Certified to an SAE J standard shall follow this procedure. Certification of a product is voluntary, however, this certification process is mandatory for those advertising meeting SAE Standard(s) requirements.

Current industry standards do not exist for determining refrigerant emissions from mobile air conditioning systems. Test procedures are not common between production component suppliers in establishing leakage values. This “System Leakage Chart” has been developed from industry experience of expected refrigerant leakage gains from system design resulting from technology changes. It provides a rating value of various technologies that are currently available. The “Leakage Chart” can be expanded as new technologies are offered and/or developed. This document provides the information to develop an Excel file template “Leakage Chart” for making system analysis. It is not the intent of this Standard to define the refrigerant emissions from a mobile air conditioning system. It is to only define a system rating based upon the technology used.
