MORRIS TOWNSHIP, N.J.
, Aug. 8, 2013 /PRNewswire/ -- Honeywell (NYSE: HON) issued the following statement following the report-out of the German Federal Motor Transport Authority (KBA) about its recent tests of the new low-global-warming-potential (GWP) refrigerant HFO-1234yf:
"KBA's tests again demonstrate that using HFO-1234yf creates no serious risks, and as a result it will not pursue action under
Product Safety Act. With the exception of Daimler, there is broad consensus that HFO-1234yf poses no greater risk than HFC-134a in cars.
"We acknowledge that KBA was put in the unenviable position of devising its own test because of a single automaker's decision not to comply with the EU Mobile Air Conditioning (MAC) Directive, which took effect this past
. KBA's results are not surprising because automobile manufacturers routinely incorporate materials that are far more highly flammable than HFO-1234yf into their vehicle designs, including motor oil, automotive transmission fluid, radiator antifreeze, brake fluid, and compressor lubricant – not to mention fuel.

"Honeywell and others have previously expressed concerns over KBA's testing protocols, which did not follow industry standards. SAE International, the world's most respected automotive engineering organization, has used globally accepted protocols to complete comprehensive Cooperative Research Programs (CRPs) to evaluate HFO-1234yf. Those programs have definitively determined that HFO-1234yf is safe. The CRPs included technical experts at automotive manufacturers and suppliers around the world, and used a wide range of information and data, including actual crash test results. These studies also employed fault-tree analysis, which evaluates the probability of a fire or other adverse conditions based on real data. This type of analysis has been proven to be a more accurate evaluation than any single test, which may be unintentionally flawed, biased or misleading.
