本SAE标准的目的是为HFC-134a（R-134a）制冷剂的回收提供最低性能和操作特性要求，该制冷剂回收设施将按照适当的AHRI 700标准对其进行处理，或者允许使用SAE J2788或SAE J3030认证的设备对回收的制冷剂进行现场再循环，达到SAE J2788规范。使用该设备从移动式空调（A/C）系统中取出的制冷剂直接返回移动式A/C系统是不可接受的。在回收制冷剂之前，将使用SAE J2912认证的标识符来识别系统的内容物。

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.
