MORRIS TOWNSHIP, N.J., June 25, 2013 /PRNewswire/ -- Honeywell (NYSE: HON) announced today that SAE International, the world's leading automotive engineering association, has concluded that Honeywell's new low-global-warming-potential mobile air conditioning refrigerant, HFO-1234yf, is safe for use in automobiles after completing an expanded and extensive evaluation.
The SAE International Cooperative Research Project (CRP) also said that all 11 global automakers who participated in the project "have indicated agreement with these conclusions" and called testing conducted by Daimler late last year that raised questions about the refrigerant's flammability "unrealistic."
"After extensive testing and analysis, the new CRP concluded that the refrigerant release testing completed by Daimler was unrealistic," the SAE CRP said in its final summary. "Their testing created extreme conditions that favored ignition while ignoring many mitigating factors that would be present in an actual real-world collision."
"The conclusions from SAE's latest expanded evaluation, combined with years of extensive testing in the U.S., Europe and elsewhere, again leaves no doubt that HFO-1234yf is safe for automotive applications," said Ken Gayer, vice president and general manager for Honeywell Fluorine Products. "The fact that all 11 global automakers participating in the project agreed with the SAE CRP's conclusions is further proof that this product can be used safely."The latest CRP included European, North American, and Asian automakers, including Chrysler/Fiat, Ford, General Motors, Honda, Hyundai, Jaguar Land Rover, Mazda, PSA, Renault and Toyota. HFO-1234yf, a highly-efficient, safe and effective replacement for HFC-134a, is already in use by the auto industry. It is being adopted by automakers in part to meet the European Union's Mobile Air Conditioning (MAC) Directive, which aims to reduce the greenhouse gas emissions of air-conditioning systems in passenger cars and light commercial vehicles. The directive requires that refrigerants in all new type vehicles sold in Europe after Jan. 1, 2013, have a global-warming potential (GWP) below 150 and that all cars sold after 2017 meet the lower GWP requirement. HFO-1234yf has a GWP of 4 and reduces global warming impact by 99.7 percent compared with HFC-134a. According to third-party data, HFO-1234yf's adoption in cars today would have the greenhouse gas equivalent impact of removing more than 4 million cars from European roads.
