This standard is for R-1234yf recovery (extraction) only equipment for on-site refrigerant recovery from Mobile Air Conditioning (MAC) systems. NOTE: R-1234yf is a mildly flammable refrigerant [refrigerants called mildly flammable have a maximum burning velocity oflt; 0.10 m/s when tested at 23 ??and 101.3 kPa] (ASHRAE 34 and ISO 817 Class 2L). Purpose The purpose of this SAE Standard is to provide minimum performance and operating requirements for equipment used to recover R-1234yf. Recovered refrigerant is to be returned to a refrigerant reclamation facility that will process it appropriately as per AHRI 700 standard@ or it may be locally recycled using on-site equipment designed and certified to SAE J2843 standard which will process the refrigerant to SAE J2099 standard. It is not acceptable that the refrigerant removed from a MAC system with this equipment be directly returned to any MAC system without further processing as described. This information applies to equipment used to service automobiles@ light trucks@ and other vehicles with similar R-1234yf MAC systems. Refrigerant recovery equipment is required to ensure adequate refrigerant recovery and to reduce emissions during the removal of refrigerant from mobile air conditioning systems. Equipment shall be certified to meet all performance requirements outlined in this document and international and regional construction and safety requirements as outlined in Section 9 of this document.
