HFC-134a Mobile Air Conditioning System Refrigerant Emission Chart
- Ground Vehicle Standard
Published August 28, 2008 by SAE International in United States
The original SAE J2727 "Emission Chart" provided a rating system for comparing mobile A/C systems and was not intended to define mobile A/C system refrigerant emission. It had been developed from industry experience of expected system refrigerant emission based upon currently available technologies. The "System Emissions Chart" now contained in this revision is intended to serve as a means of estimating the annual refrigerant emissions rate (grams per year) from new production A/C systems equipped with specified component technologies. It provides emission values for various component technologies that are currently available, and can be expanded as new technologies are commercialized. This document provides the information to develop an Excel file template "System Emissions Chart" for system emission analysis. The chart includes automotive compressor technologies for conventional mobile air conditioning systems as well as those using semi-hermetic compressors. This standard can be considered a companion document to SAE J2763 Test Procedure for Determining Refrigerant Emissions from Mobile Air Conditioning Systems. SAE J2727 estimates system emissions, taking into account production assembly variation. SAE J2763 may be used to quantify emissions from properly assembled systems.
Industry standards did not exist for measuring, or estimating, refrigerant emissions from mobile air conditioning systems when the original version of SAE J2727 was created in 2005. This revision is based on laboratory measurements and field correlations and supersedes the original, which provided a relative system emission rating based solely on component technology used in the system combined with expert input regarding relative emission rates of components.

Interior Climate Control Fluids Committee
The Interior Climate Control Fluids 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.
