Refrigerant Purity and Container Requirement for Carbon Dioxide (CoD2 R-744) Used in Mobile Air-Conditioning Systems
This SAE Standard applies to Carbon Dioxide R-744 refrigerant used to service motor vehicle passenger air-conditioning (A/C) systems designed to use CO2 (R-744). Carbon dioxide (R-744) when used as a refrigerant in mobile air-conditioning systems shall contain an odorant as an identification of refrigerant leaking from the system.
Hermetically sealed, refrigerated cargo systems are not covered by this document.
Rationale: The purpose of this SAE Standard is to establish the minimum level of purity, odorant requirement and container specifications for Carbon dioxide (CO2) refrigerant use in, mobile air-conditioning (A/C) systems.
