Product Code:SAE J639
Title:Safety Standards for Motor Vehicle Refrigerant Vapor Compresssions Systems
Issuing Committee:Interior Climate Control Committee
Scope:This SAE Recommended Practice is restricted to mechanical vapor compression refrigerant systems which provide cooling for the occupant's compartment. This document provides guidelines for refrigerant containment and safety for a mobile air- conditioning (A/C) system. The purpose is to also provide cautionary statements for the mobile A/C industry to alert service technicians to the inadvisability and the possible health and safety effects associated when venting refrigerant during service of mobile A/C systems. It is not intended to restrict the use of, or further development of, other types of refrigeration systems for passenger compartment cooling. Should other systems be found practical at some future time, this document may be amended or an additional recommended safety practice drawn up for such other systems. This document only addresses CRC-12 (R-12) and HFC-134a (R-134a) refrigerants. To prevent mobile A/C system refrigerant contamination, all other alternate refrigerants considered for automotive use require unique service fittings.
