September 25, 2012: Even though several manufacturers (Daimler included) have already begun using R-1234yf, Daimler announces that in-house testing shows it can cause a fire in a crash. They decide to continue using R-134a despite EC regulations until a suitable alternative can be developed. October 2012: SAE International launches a fourth Cooperative Research Program (CRP) specifically to address Daimler's claims. All OEMs are (again) invited to participate. October 2012: Other German automakers announce solidarity with Daimler, but with no new platforms scheduled for release this year, they are not in violation of the law. Spring 2013: The German KBA (federal motor transport authority) begins their own vehicle testing program to investigate refrigerant flammability. Meanwhile, Daimler is granted an extension of type approval for three Mercedes-Benz models, effectively back-dating those platforms and allowing them to continue using R134a under German law. June 2013: The European Union (EU) Industry Commissioner begins formal infringement procedures, giving the German government ten weeks to initiate sanctions against Daimler for not complying with EU law. Meanwhile, the SAE Cooperative Research Program reports the risks posed by R-1234yf are "well below" those commonly accepted in a vehicle. The report calls Daimler's test "unrealistic," saying it was designed to increase the possibility of fire in a collision. July 2013: France refuses to register three Mercedes-Benz models for sale in that country. Germany reportedly pressures other EU countries to weaken or postpone implementing lower CO2 emission limits. August 2013: Although the German KBA finds "no serious risk" in using R1234yf, the German government supports Daimler's decision to continue using R134a. Thus begins a formal process giving the European Commission 10 weeks http://www.agscompany.com http://www.agscompany.com http://agscompany.com http://www.macsw.org/imis15/MACS/Publications/ACtion_Reader_Reply/MACS/Publications/ACTION/ACtion_Reader_Reply.aspx?hkey=ac24bddb-c045-442a-813c-cbf05f88ac4d
