SAE International Announces New Technical Standards for HFO-1234yf Refrigerant

WARRENDALE, Pa., Feb. 9, 2011 - The SAE Interior Climate Control Standards Committee has announced the publication of new SAE International documents covering the use of HFO-1234yf refrigerant in mobile air conditioning systems. This refrigerant was evaluated in 2009 within an SAE Cooperative Research project and deemed safe for use by the industry group which worked together in the SAE CRP1234.

Over the last several years, this committee’s membership and extensive industry efforts, including SAE Cooperative Research Projects has resulted in the development or revision of 18 SAE International J standards for this new refrigerant. New vehicles entering production later this year will be equipped with this new low Global Warming Potential (GWP) refrigerant.

These SAE International standards cover MAC systems using HFO-1234yf refrigerant design requirements, service equipment and certification procedures for system components, service equipment and technician training.

Over the years, SAE International J Standards have been referenced by regulatory authorities, such as J639 Safety Standards for Motor Vehicle Refrigerant Vapor Compression Systems, which cover system design, components and service equipment for refrigerants used in MAC systems.

The following documents are available on the SAE International Web Site:
