The purpose of this SAE Standard is to provide minimum performance and operating feature requirements for the recovery of HFC-134a (R-134a) refrigerant to be returned to a refrigerant reclamation facility that will process it to the appropriate AHRI 700 Standard or allow for on-site recycling of the recovered refrigerant to SAE J2788 specifications by using SAE J2788 or SAE J3030 -certified equipment. It is not acceptable that the refrigerant removed from a mobile air-conditioning (A/C) system with this equipment be directly returned to a mobile A/C system. An identifier certified to SAE J2912 is to be used to identify the contents of the system prior to recovery of the refrigerant. This information applies to equipment used to service automobiles@ light trucks@ and other vehicles with similar HFC- 134a (R-134a) A/C systems. Improved refrigerant recovery equipment is required to ensure adequate refrigerant recovery to reduce emissions and provide for accurate recharging of mobile air conditioning systems. Therefore@ this standards supercedes@ SAE J1732
