SAE International Cooperative Research Project says latest extensive evaluation of HFO-1234yf refrigerant shows no change in its previous safety conclusions; Says concerns raised by one automaker based on “unrealistic” testing

MORRIS TOWNSHIP, N.J., Feb. 12, 2013 – Honeywell (NYSE: HON) announced today that SAE International, the world’s leading automotive engineering association, has reiterated that it has a “high level of confidence” that Honeywell’s new low-global-warming-potential mobile air conditioning refrigerant, HFO-1234yf, is safe for use in automobiles.

SAE International’s Cooperative Research Project (CRP), which included technical experts from 11 global automakers, said in a press release Monday that “the high level of confidence” that SAE CRP has in the safety of the refrigerant “continues to grow.”

The CRP said that the findings of its original evaluation of the refrigerant “remain well founded” and that the refrigerant “posed no greater risk than any other engine compartment fluids.” The CRP also said that testing conducted by Daimler late last year that raised questions about safety was “unrealistic” and used “extremely idealized conditions … while ignoring actual collision scenarios.”

“The SAE’s latest evaluation, combined with years of other extensive testing, leaves no doubt that HFO-1234yf is safe for automotive applications,” said Terrence Hahn, vice president and general manager for Honeywell Fluorine Products. “Automakers globally continue to adopt this new, effective solution to comply with new environmental regulation, including the European Union’s Mobile Air Conditioning (MAC) Directive.”

HFO-1234yf, a highly-efficient, safe and effective replacement for HFC-134a, is already in use by the auto industry. It reduces global warming impact by 99.7 percent over HFC-134a and, according to third-party data, its adoption in cars today would have the greenhouse gas equivalent impact of removing more than 4 million cars from European roads.

SAE initiated the latest CRP after Daimler raised questions about the refrigerant’s flammability. SAE said the CRP’s latest evaluation was expanded based on Daimler’s concerns, but that “the CRP has found that the refrigerant is highly unlikely to ignite and that ignition requires extremely idealized conditions.”

“The SAE CRP team of OEMs has also identified that the refrigerant release testing completed by Daimler was unrealistic by creating the extremely idealized conditions for ignition while ignoring actual real world collision scenarios,” the SAE said in its announcement. “These conditions include specific combinations of temperature, amount and distribution of refrigerant, along with velocity, turbulence, and atomization, which are highly improbable to simultaneously occur in real-world collisions.”

By comparison, the CRP said its safety evaluation of the refrigerant used, “universally accepted engineering methods, including analysis of recent OEM testing from actual vehicle crash data, on-vehicle simulations, laboratory simulations, bench tests, and over 100 engine compartment refrigerant releases.”

The CRP said it is continuing to review use of the refrigerant. “The CRP continues to populate the fault trees to insure completeness of the risk assessment through pragmatic and factual input based on the latest and most accurate data available,” the CRP said. “Fault tree analysis as conducted by the CRP is the most appropriate approach for evaluating risks of new alternative refrigerants. This approach has been recommended and employed by numerous public and private organizations including the U.S. Environmental Protection Agency, the U.S. Department of Energy, the International Electrotechnical Commission, the European Union Joint Research Centre and the United Kingdom Health and Safety Executive.”

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 is being adopted by automakers in part to meet the European Union’s 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.

SAE International, formerly known as the Society of Automotive Engineers, is an independent, global association of more than 133,000 engineers and related technical experts in the aerospace, automotive and commercial-vehicle industries.

Under rare conditions, HFO-1234yf exhibits mild flammability, at levels significantly lower than highly flammable materials already present under the hood of an automobile, including motor oil, automotive transmission fluid, radiator antifreeze, brake fluid, and compressor lubricant – not to mention fuel.

Company fully prepared to support automakers with safe, effective HFO-1234yf refrigerant, which reduces greenhouse gas impact by 99.7 percent compared with current refrigerant HFC-134a

MORRIS TOWNSHIP, N.J., Jan. 15, 2013 – Honeywell (NYSE: HON) today said it welcomed implementation of the European Union’s Mobile Air Conditioning (MAC) Directive, aimed at reducing greenhouse gas emissions by requiring use of automotive refrigerants with significantly lower global warming impact.

The directive came into force on Jan. 1, 2013, and the company said it is fully prepared to supply automakers with HFO-1234yf, a new lower-global-warming-potential refrigerant that has been proven to be a safe and effective replacement for HFC-134a and is already in use by the auto industry.

“Honeywell has been preparing to assist automakers meet this milestone directive, investing in research to develop HFO-1234yf, which is the alternative refrigerant that best meets the requirements for safety, effectiveness and energy efficiency,” said Dr. Ian Shankland, chief technology officer for Honeywell Performance Materials and Technologies. “HFO-1234yf is a near drop-in replacement for HFC-134a, making it easy and cost-effective for automakers to comply with the MAC Directive.”

The European Union’s F-Gas Regulation (842/2006), passed in July 2006 and enforced through the MAC Directive, aims to reduce emissions of specific fluorinated greenhouse gases in the 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. HFC-134a has a GWP of 1,430, while HFO-1234yf has a GWP of 4, far exceeding the MAC Directive requirement.

According to a third-party study, if all cars in Western Europe today were converted from HFC-134a to HFO-1234yf, it would result in a reduction of an equivalent 8 million tons of carbon dioxide emissions per year ‒ or removing 4 million cars from the road.

The European Commission, at a December 2012 meeting of its Technical Committee – Motor Vehicles (TCMV), reconfirmed that the MAC directive would be fully enforced starting on Jan. 1.

HFO-1234yf has been exhaustively and extensively evaluated by respected global testing agencies, including SAE International, which concluded after a three-year evaluation of the refrigerant involving 15 global automakers, 17 top automotive suppliers and 18 international, independent research institutes that the refrigerant is safe and effective in automotive applications.

SAE International, formerly known as the Society of Automotive Engineers, is an independent, global association of more than 133,000 engineers and related technical experts in the aerospace, automotive and commercial-vehicle industries.

Overwhelming evidence gathered by collaborative auto industry processes has demonstrated new low-global-warming offering can safely be used in automobiles

MORRIS TOWNSHIP, N.J., Dec. 14, 2012 – Honeywell (NYSE: HON) today said it is confident that SAE International, recognized as the world’s leading automotive engineering association, will reconfirm that HFO-1234yf, Honeywell’s new low-global-warming-potential automotive air conditioning refrigerant, is safe for use in automobiles.

SAE International, in announcing an update on its fourth and latest Cooperative Research Project (CRP) on the refrigerant, said, “To date, the majority of the OEMs involved in the new CRP do not believe that any of the new information reviewed will lead to a change in the overall risk assessment.”

“With the exception of Daimler, no OEM in the CRP has provided information that would suggest a concern for the safe use of R-1234yf in their vehicles,” SAE International said.

“Based on today’s announcement, Honeywell continues to believe that SAE International’s latest evaluation will only reconfirm the overwhelming body of data – including rigorous and comprehensive studies conducted in Europe, the U.S. and Japan – that have clearly and repeatedly determined that HFO-1234yf is safe for use in automobiles,” said Dr. Ian Shankland, chief technology officer for Honeywell Performance Materials and Technologies. “HFO-1234yf is a safe and effective refrigerant, and it is better for the environment.”

SAE International, formerly known as the Society of Automotive Engineers, is an independent, global association of more than 133,000 engineers and related technical experts in the aerospace, automotive and commercial-vehicle industries. Previously, HFO-1234yf was the subject of comprehensive testing conducted over a three-year period under an SAE International CRP using proven, standard methods for evaluating new products and materials in automobiles. That CRP, which was sponsored by 15 global automakers, including all leading German automakers, concluded that HFO-1234yf is safe for use in automobile applications.

HFO-1234yf is a highly efficient, low-global-warming refrigerant that was developed as a direct replacement to HFC-134a in mobile air-conditioning applications. Compared with HFC-134a, HFO-1234yf offers a 99.7 percent improvement in global warming potential and far exceeds the European Union Mobile Air Conditioning (MAC) Directive requirement.

Under rare conditions, HFO-1234yf exhibits mild flammability, at levels significantly lower than highly flammable materials already present under the hood of an automobile, including motor oil, automotive transmission fluid, radiator antifreeze, brake fluid, and compressor lubricant – not to mention fuel. For a video on this topic, which includes a comparison of HFO-1234yf vs. HFC-134a and other materials, visit www.1234facts.com/resources or www.1234fakten.de/ressourcen.

SAE International’s previous research projects have addressed the issue of flammability, employing proven and universally accepted fault-tree risk assessment techniques to evaluate the real-world possibility of a fire and human impact. SAE International said in its latest statement that it has expanded its fault-tree assessment in the new CRP to “ensure that newly-identified information and testing from each of the OEMs is incorporated.”

As part of SAE International’s programs, internationally recognized laboratories – including Hughes Associates Inc. and France’s Institute National de l’Environment Industriel et des Risques (INERIS) – conducted extensive testing on flammability and safety, and all concluded that HFO-1234yf is safe for use in automobiles.
