SAE International Updates R-134a Recovery and Recycling Service Equipment Standards

WARRENDALE, Pa., Sept. 10, 2010 - SAE International announced that it has updated the equipment standards covering the recovery and onsite recycling of R-134a refrigerant used to service mobile air conditioning systems.

In December 2009, SAE International’s J2788 HFC-134a (R-134a) Recovery/Recycling Equipment and Recovery/Recycling/Recharging for Mobile Air-Conditioning Systems was published. J2788 superseded the requirements of SAE J2210 HFC-134a (R-134a) Recovery/Recycling Equipment for Mobile Air-Conditioning Systems to reduce refrigerant emissions during servicing and provides requirements for charging refrigerant into mobile air conditioning systems.


In October 1995, SAE International’s J1770 automotive refrigerant recovery/recycling equipment intended for use with both R-12 and R-134a was issued. This equipment does not meet current start of art to assure refrigerant recovery from the MAC system and does not provide any method to assure the system is accurately recharged with refrigerant.


Both J1770 and J2210 Standards have been canceled because they don’t meet current industry refrigerant containment of emissions criteria when recovering and charging    R-134a refrigerant during service of MAC systems.

SAE International’s Interior Climate Control Standards Committee has developed requirements for the new R-1234yf refrigerant to be used in future MAC systems. Among the new SAE standards is J2843 R-1234yf Recovery/Recycling/Recharging Equipment for Flammable Refrigerants for Mobile Air-Conditioning and J2851 R-1234yf Refrigerant Recovery Equipment for Mobile Automotive Air-Conditioning Systems. It is anticipated that the new R-1234yf SAE Standards and Recommended Practices will be published in 2011.
