Protection of the Stratospheric Ozone: Motor Vehicle Air Conditioning System Servicing

The Environmental Protection Agency (EPA) is adopting three technical standards developed by SAE International (SAE) for equipment that recovers, recycles, and/or recharges the refrigerant 2,3,3,3- Tetrafluoroprop-1-ene (HFO-1234yf or R-1234yf) in motor vehicle air conditioners (MVACs). The three standards are SAE J2843, SAE J2851, and SAE J3030. This rule adopts the most current versions of these standards by incorporating them by reference into the regulations under Title VI of the Clean Air Act (CAA).
