SAE J3112 – A/C Compressor Oil Separator Effectiveness Test Standard

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.
