Scope:

This SAE Standard applies to: • recycled R-134a refrigerant, used in servicing of motor vehicle air conditioning (A/C) systems that were designed for use with R-12 and have been retrofitted for use with R-134a; • recycled R-134a refrigerant, used in servicing of motor vehicle air conditioning (A/C) systems that were designed for use with R-134a; • recycled R-1234yf refrigerant, used in servicing of motor vehicle air conditioning (A/C) systems that were designed for use with R-1234yf. Hermetically sealed, refrigerated cargo systems are not covered by this document.

Rationale:

Refrigerant used in mobile air conditioning systems, under Federal Law, cannot be vented at service. The refrigerant can be recovered and generally be reused by using onsite recovery and recycling equipment that meet the appropriate SAE service equipment requirements. This SAE Standards identifies the level of purity of recovered and recycled refrigerant that can be considered acceptable for re-used in R-134a and R-1234yf mobile air conditioning systems.
