The scope of this SAE Information Report is an evaluation of the ports and tools used on automotive air-conditioning systems to evacuate and charge systems with approved refrigerants during vehicle service. A task force was formed in April 2021 to perform this evaluation and concluded its work in September 2021. The scope of the task force was to evaluate issues being reported from service repair shops with air-conditionings service ports and the tools being used to connect to these ports. The task force also evaluated published SAE J Standards and discovered many of these standards did not include the necessary requirements for service ports and tools. The task force published a final report of its findings and recommendations. The report includes recommendations to correct and publish new SAE Standards related to the scope of this project.

This SAE Standard establishes the test conditions and reporting method for quantifying refrigerant circuit oil circulation rate (OCR) reduction effectiveness of mobile air conditioning compressors using R-134a and R-1234yf refrigerants that include oil separators and/or other design features for the purpose of reducing the OCR in the refrigerant circuit. This standard and the OCR values it produces are not intended to make judgement on suitability of OCR values with regard to compressor durability.

This test procedure describes the corrosion test of brazed aluminum condensers as well as the subsequent assessment of the tested components and the applicable assessment criteria.

This SAE Standard covers the Mini-Shed testing methodology to measure the rate of refrigerant loss from an automotive air conditioning (A/C) system. This SAE procedure encompasses both front and rear air conditioning systems utilizing refrigerants operating under sub-critical conditions.

This SAE Standard covers the mini-shed testing methodology to measure the rate of refrigerant loss from an automotive air conditioning (A/C) system. This SAE procedure encompasses both front and rear air conditioning systems utilizing refrigerants operating under sub-critical conditions. The SAE procedure will cover multiple refrigerants to emission testing and is utilized for evaluating air condtioning systems. Heat pump systems can be evaluated, however, will have different usage and mission profiles.

The scope of SAE J3143 will cover non-metallic line assemblies intended for containing and circulating lubricant (PAG, POE compressor oils), liquid, and gaseous R-134a, R-152a, or R-1234yf refrigerant in automotive air-conditioning systems. SAE J3143 will also provide the necessary hose permeation values used in SAE J2727 mobile air-conditioning system refrigerant emission charts. The assembly shall be designed to minimize permeation of the refrigerant, contamination of the system, and to be functional over a temperature range of -30 to 125 °C. Specific construction details are to be agreed upon between user and supplier. Figure 1 shows a typical A/C system with TXV.

The scope of SAE J3062 covers hose intended for containing and circulating lubricant, liquid, and gaseous R-134a, R-152a, and/or R-1234yf refrigerant in automotive air-conditioning systems. The hose shall be designed to minimize permeation of the refrigerant, contamination of the system, and to be functional over a temperature range of -30 to 125 °C. Specific construction details are to be agreed upon between the user and supplier. Requirements for the hose used in coupled automotive refrigerant air-conditioning assemblies are included in SAE J2064. SAE J3062 separates requirements for the hose used in these assemblies into its own standard. SAE J2064 also provides the necessary refrigerant permeation values used in SAE J2727. Mobile air-conditioning system refrigerant emissions rates are established in SAE J2727 emission charts and are important. The certified coupling of MAC hose assemblies is required in meeting certain regulatory requirements.
