The purpose of this SAE Recommended Practice is to establish the specific criteria for the selection of a replacement refrigerant for mobile CFC-12 (R-12) air-conditioning (A/C) systems. This document provides guidelines for qualifying candidate refrigerant. The requirements include laboratory and field testing. The alternate refrigerant shall provide comparable system performance as CFC-12 (R-12) as defined herein. The vehicle testing shall be conducted on representative vehicle manufacturer's product line, in which the refrigerant is intended to be used, such as cycling clutch orifice tube, constant run orifice tube, cycling clutch expansion valve, or continuous run expansion valve refrigerant system. This document is complete only when combined with the requirements of SAE J1657.

This SAE Standard applies to the application of ultraviolet leak detection to service mobile air-conditioning systems.

This SAE Standard applies to fluorescent refrigerant leak detection dye injection equipment for use in ultraviolet leak detection when servicing mobile air-conditioning systems.

This information applies to refrigerant used to service automobiles, light trucks, and other vehicles with similar CFC-12 (R-12) systems. Systems used on mobile vehicles for refrigerated cargo that have hermetically sealed, rigid pipe, are not covered in this document.

The purpose of this SAE Recommended Practice is to provide criteria for determining the acceptability of candidate retrofit refrigerants to replace CFC-12 (R-12) in mobile A/C systems originally designed to use CFC-12 (R-12).

This SAE Recommended Practice is restricted to mechanical vapor compression refrigerant systems that provide cooling for the occupant’s compartment. This document provides guidelines for refrigerant containment and safety for a mobile air-conditioning (A/C) system. It is not intended to restrict the use of, or further development of, other types of refrigeration systems for passenger compartment cooling. Should other systems be found practical at some future time, this document may be amended or an additional recommended safety practice drawn up for other types of systems. This document only addresses CFC-12 (R-12) and HFC-134a (R-134a) refrigerants. To prevent mobile A/C system refrigerant contamination, all other alternate refrigerants considered for automotive use require unique service fittings.

This SAE Standard applies to refrigerant vapor compression systems that provide cooling and/or heating for passenger cars, light trucks and commercial vehicles (on and off road) that use automotive type mobile air conditioning (MAC) systems. Large trucks, buses and other vehicles that do not use typical automotive a/c systems or use refrigerants not listed in this document are not covered by this standard. This standard covers any vehicle with a MAC system using a belt or electric motor driven compressor. This document provides standards for design, assembly, test and service of MAC systems to minimize environmental, health and safety impacts. Also included are cautionary statements for the service industry to alert technicians to the inadvisability and possible health or safety effects associated with venting refrigerant during service. It is not intended to restrict the use, or further development, of other types of refrigeration systems for mobile air conditioning applications.

This information applies to refrigerant used to service automobiles, light trucks, and other vehicles with similar CFC-12 systems. Systems used on mobile vehicles for refrigerated cargo that have hermetically seated, rigid pipe are not covered in this document.

This SAE Standard applies to HFC-134a refrigerant used to service motor vehicle passenger compartment air-conditioning systems designed or retrofitted to use HFC-134a. Hermetically sealed, refrigerated cargo systems are not covered by this document.

This SAE Standard covers reinforced rubber, reinforced thermoplastic, or otherwise constructed hose, or hose assemblies, intended for conducting liquid and gaseous refrigerants for service connections from mobile air-conditioning systems to service equipment such as a manifold gauge set and vacuum pumps or for use internally, in charging stations or service equipment intended for use in servicing mobile air-conditioning systems.

To provide a procedure to inspect a refrigerant cylinder used in equipment servicing mobile air-conditioning (A/C) systems. This includes the pressure cylinder used for refrigerant recovery/recycling and charging equipment.

This SAE Standard applies to new refrigerant used in motor vehicle passenger air-conditioning (A/C) systems designed to use HFC-134a. Hermetically sealed, refrigerated cargo systems are not covered by this document.

The purpose of this SAE Standard is to provide equipment specifications for CFC-12 (R-12) recycling equipment. This information applies to equipment used to service automobiles, light trucks, and other vehicles with similar CFC-12 (R-12) air-conditioning (A/C) systems. Systems used on mobile vehicles for refrigerating cargo that have hermetically sealed systems are not covered in this document. The equipment in this document is intended for use with refrigerant that has been directly removed from, and intended to be returned to, a mobile A/C system. Should other revisions due to operational or technical requirements occur, this document may be amended.

Refrigerant containment is an important part of servicing mobile air-conditioning (A/C) systems. This procedure provides guidelines for technicians for servicing mobile A/C systems and operating refrigerant recycling equipment designed for HFC-134a (R-134a) (described in SAE J2210).

During service of mobile air-conditioning (A/C) systems, containment of the refrigerant is important. This procedure provides service guidelines for technicians when repairing vehicles and operating equipment defined in SAE J1990.
