World's Leading Automotive Engineering Organization Reconfirms That
Honeywell's Low-Global-Warming Refrigerant Is 'Safe and Effective'
SAE International Cooperative Research Project says updated analysis of
HFO-1234yf refrigerant does not change prior findings; Says 'unrealistic' test
conducted by one automaker does not represent actual crash conditions
MORRIS TOWNSHIP, N.J., April 23, 2013
MORRIS TOWNSHIP, N.J., April 23, 2013 /PRNewswire/ --Honeywell (NYSE: HON)
announced today that SAE International, the world's leading automotive
engineering organization, has reconfirmed that Honeywell's new
low-global-warming-potential mobile air conditioning refrigerant, HFO-1234yf,
is "safe and effective to use in automotive applications."
SAE International's Cooperative Research Project (CRP) said that it has
carefully evaluated extensive testing on HFO-1234yf, including collision
scenarios, and has reconfirmed its finding that HFO-1234yf is safe for use in
automobile air conditioning.
The evaluation involved technical experts from Fiat-Chrysler, Ford, General
Motors, Honda, Hyundai, Jaguar Land Rover, Mazda, PSA Peugeot Citroen, Renault
The CRP also concluded that a test conducted by Daimler late last year, which
raised questions about safety, was "unrealistic" and "not an appropriate test
to verify the safety of refrigerant applications in vehicles" because it "did
not include any actual vehicle collisions or the mitigating factors that occur
in an actual collision."
"The CRP's recent announcement again confirms that HFO-1234yf is safe for use
in mobile air conditioning," said Dr. Ian Shankland, chief technology officer
for Honeywell Performance Materials and Technologies. "Extensive testing by
global automakers and third-party experts alike proves that HFO-1234yf is
safe. HFO-1234yf is being readily adopted by automakers around the world
because of its safety, effectiveness and availability today to meet
environmental regulations such as the European Union's Mobile Air Conditioning
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.
HFO-1234yf was the subject of comprehensive testing conducted by an SAE CRP
from 2007 to 2009. That CRP, which was sponsored by 15 global automakers,
including all leading German automakers, major suppliers and 18 international,
independent research institutes, concluded that HFO-1234yf is safe for use in
SAE initiated the latest CRP after Daimler raised questions about the
refrigerant's flammability in the event of a crash. Those questions were based
on in-house testing of Daimler's own vehicles without the participation of any
reputable third party and without consultation with others in the industry.
The SAE concluded that "the risk of passenger exposure to a vehicle fire
associated with this refrigerant is exceptionally remote."
"The SAE CRP team of OEMs has concluded that the refrigerant release testing
conducted by Daimler is unrealistic and that it is not an appropriate test to
verify the safety of refrigerant applications in vehicles," the SAE said in
its announcement. "The Daimler testing did not include any actual vehicle
collisions or the mitigating factors that occur in an actual collision."
By comparison, the CRP said its safety evaluation, which used fault-tree
analysis, "is the most appropriate approach for evaluating risks of new
alternative refrigerants." Fault-tree analysis, which evaluates the
probability of a safety accident, 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.
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. HFO-1234yf has a GWP
of 4, compared with the current refrigerant, HFC-134a, which has a GWP of

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.
