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.

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.
