Scope
This Standard provides an overview of results and requirements needed to remove refrigerant from a mobile air conditioning system for determining refrigerant emissions (leakage).
This reclaim procedure for use on fleet vehicles in a field service environment should produce an accuracy and repeatability sufficient to determine refrigerant loss within 2 g.
Rationale
The removal of refrigerant from a mobile air conditioning system to determine the direct refrigerant emissions is a difficult procedure to do accurately. As part of the SAE I-MAC Cooperative Research Program a detail study was conducted on accurate removal of refrigerant from a mobile air conditioning system. Additional studies on the removal of HFC-134a from mobile air conditioning systems have been completed by others in the automobile industry. Use of commercially available equipment, including equipment meeting SAE J Standards, will not allow complete removal of refrigerant from a mobile air conditioning system in order to determine the direct refrigerant emissions. It is difficult and unreliable to remove refrigerant from mobile A/C systems and use this to quantify system emissions.

Issuing Committee
Interior Climate Control Service Committee
The Interior Climate Control Service Committee is responsible for developing and maintaining SAE Standards, Recommended Practices, and Information Reports that serve as guidelines for technicians who service mobile air conditioning systems and operate refrigerant recycling equipment as it applies to automobiles, light trucks and other vehicles with similar R12 systems. Participants in the SAE Interior Climate Control Standards Committee include OEMs, suppliers, consulting firms, government, and other interested parties.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
