WARRENDALE, Pa., Dec. 14, 2012 /PRNewswire-USNewswire/ --  The SAE
International Cooperative Research Project (CRP1234-4) team was recently
established to perform an updated engineering review of R-1234yf refrigerant
usage in vehicles. The group has been regularly meeting to review and share
test information completed since the close of the original CRP1234-3 in 2009.
The previous study concluded that R-1234yf is a safe and acceptable
alternative refrigerant for mobile air conditioning systems that can be used
to meet new environmental and consumer needs.

The new CRP team began by conducting a detailed review of the original Fault
Tree Analysis (FTA) and chose to expand the trees to ensure that
newly-identified information and testing from each of the OEMs is
incorporated. This study has highlighted concerns with relying on one test to
be reflective of real world collisions across vehicle applications.

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. Several OEMs have shared test results regarding their vehicles.
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.

R-1234yf is approved as an alternative refrigerant by the U.S. EPA and is
REACH registered in Europe. Many new vehicles in Europe have received "type
approval" to use this refrigerant. It is already in use in vehicles in North
America and Europe.

The CRP team continues to hold regular conference calls and face-to-face
meetings and expects to be able to provide updated progress reports as new
information becomes available. The next report is expected by the middle of
February. To insure thoroughness, the OEM team is working quickly but
diligently to complete the expanded fault trees and several of the OEM members
continue to do testing toward that goal. The new risk assessment and
publication of the findings is planned for completion in the second quarter of
2013.

The team includes 13 members: Audi, BMW, Chrysler/Fiat, Daimler, Ford,
General Motors, Honda, Hyundai, Jaguar Land Rover, Mazda, PSA, Renault and
Toyota.
