Criteria for Refrigerant Identification Equipment for Use with Mobile Air-Conditioning Systems(STABILIZED May 2011)
This SAE Standard applies to refrigerant identification equipment to be used for identifying refrigerant CFC-12 (R-12) and HFC-134a (R-134a) refrigerant when servicing a mobile A/C system or for identifying refrigerant in a container to be used to charge a mobile A/C system. Identification or other refrigerants are the option of the equipment manufacturer.
This document applies to R12 refrigerant which has been phased out of OEM usage since 1995. This standard covers technology, products, or processes which are mature and not likely to change in the foreseeable future.
