本SAE标准的目的是确定回收/再循环设备的具体最低设备要求，该设备拟与R12和R134a一起使用，用于直接从移动式空调（a/C）系统中移除并在其中重复使用的通用制冷剂回路。本文件不适用于R12和R134a使用的设备，这些设备有一个共用的外壳，每个制冷剂都有单独的回路。

The purpose of this SAE Standard is to establish the specific minimum equipment requirements for recovery/recycling equipment intended for use with both R12 and R134a in a common refrigerant circuit that has been directly removed from, and is intended for reuse in, mobile air-conditioning (A/C) systems. This document does not apply to equipment used for R12 and R134a having a common enclosure with separate circuits for each refrigerant.
