本SAE标准的目的是提供CFC-12(R-12)回收的设备规格，以便返回到制冷剂回收设施，该设施将按照适当的ARI标准（空调和制冷剂协会）对其进行处理，或者允许在经认证符合SAE J1991要求的设备中回收回收的制冷剂。根据现有规则，美国EPA要求使用经认证符合SAE J2209的回收设备从移动空调（A/C）系统中移除的制冷剂只能使用由同一公司或个人所有的符合SAE J1991的设备进行回收。 使用该设备从移动式空调系统移除的制冷剂直接返回移动式空调系统是不可接受的。 本信息适用于用于维修汽车、轻型卡车和其他具有类似CFC-12(R-12)系统的车辆的设备。

The purpose of this SAE Standard is to provide equipment specifications for CFC-12 (R-12) recovery for return to a refrigerant reclamation facility that will process it to the appropriate ARI Standard (Air Conditioning and Refrigerant Institute) or allow for recycling of the recovered refrigerant in equipment that is certified to meet the requirements of SAE J1991. Under the existing rule, the U.S. EPA requires refrigerant removed from a mobile air-conditioning (A/C) system using recovery equipment certified to meet SAE J2209 can only be recycled using equipment meeting SAE J1991 that is owned by the same company or individual. It is not acceptable that the refrigerant removed from a mobile A/C system, with this equipment, be directly returned to a mobile A/C system. This information applies to equipment used to service automobiles, light trucks, and other vehicles with similar CFC-12 (R-12) systems.
