This SAE Standard can be used to test actual vehicle IHX designs or standardized IHX samples, which can be used for comparison based on a common length and shape.
This SAE Standard provides testing and functional requirements to meet specified minimum performance criteria for electronic probe-type leak detectors. The equipment specified here will identify smaller refrigerant leaks when servicing motor vehicle air conditioning systems, including those engineered with improved sealing and smaller refrigerant charges to address environmental concerns and increase system efficiency. This document does not address any safety issues concerning the equipment design or use beyond that of sampling a flammable refrigerant, save those described in 3.1 and 3.2 of this document. All requirements of this standard shall be verified in SAE J2911.
This SAE Standard provides testing and functional requirements to meet specified minimum performance criteria for electronic probe-type leak detectors, so they will identify smaller refrigerant leaks when servicing all motor vehicle air conditioning systems, including those engineered with improved sealing and smaller refrigerant charges to address environmental concerns and increase system efficiency. This document does not address any safety issues concerning their design or use.
This SAE Recommend Practice establishes for passenger cars, light trucks, and multipurpose vehicles with GVW of 4500 kg (10000 pounds) or less, as defined by the EPA, and M1 category vehicles, as defined by the European Commission:
This SAE Recommended Practice, limited to liquid coolant systems, establishes uniform vehicle heater test procedures. Both laboratory and complete vehicle tests are specified in this document. Required test equipment, facilities, and definitions are included. NOTE— Defrosting and defogging procedures and requirements can be found in SAE J902, J381, J382, and J953.
This SAE Standard covers fittings, couplers, and hoses intended for connecting service hoses from mobile air-conditioning systems to service equipment such as charging, recovery, and recycling equipment (see Figure 1). This specification covers service hose fittings and couplers for MAC service equipment service hoses, per SAE J2843 and SAE J2851, from mobile air-conditioning systems to service equipment such as manifold gauges, vacuum pumps, and air-conditioning charging, recovery, and recycling equipment.
This specification covers an aluminum alloy in the form of honeycomb core in a non-hexagonal, flexible cell configuration with the core being treated for increased corrosion resistance and furnished only in the expanded form (see 8.5).
This SAE Standard describes methods to understand the risks associated with vehicle mobile air conditioning (MAC) systems in all aspects of a vehicle’s lifecycle including design, production, assembly, operation, and end of life. Information for input to the risk assessment is provided in the appendices of this document. This information should not be considered to be complete, but only a reference of some of the data needed for a complete analysis of the risk associated with the use of refrigerants in MAC systems.
Mobile air conditioning (MAC) systems used in passenger cars and light duty trucks are covered by these SAE Standards when servicing the refrigerant system. Technician training is required to ensure that recommended procedures are used for service and repair of MAC systems using R-12, R-134a, R-1234yf, R-744, and R-152a refrigerants. Unique requirements for each refrigerant are detailed within this standard. Technicians may be trained in any or all refrigerants. The technician shall be trained to recognize which refrigerant is being handled and how to handle it safely, and be equipped with the essential information, proper equipment, and tools which are unique to these refrigerants. This standard outlines minimum content requirements for such training programs. Training programs designed in accordance with this standard are not intended to ensure or assess the technical skills of technicians regarding the diagnosis and repair of motor vehicle air conditioners. Rather, the goal of such
This SAE Recommended Practice applies to the use, by automotive service technicians, of generally available leak detection methods to service motor vehicle passenger compartment air conditioning 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.
This SAE Standard applies to refrigerant identification equipment to be used for identifying refrigerant CFC-12 (R-12) and HFC-134a (R-134a) 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.
The intent of this specification is for the procurement of the material listed on the QPL and, therefore, no qualification or equivalency threshold values are provided.
