Product Code:SAE J1658
Title:Alternate Refrigerant Consistency Criteria for Use in Mobile Air-Conditioning Systems
Issuing Committee:Interior Climate Control Committee
Scope:This SAE Recommended Practice applies to refrigerant blends (multicomponent refrigerants) intended for use as retrofit refrigerants to replace CFC-12 (R-12) in mobile air-conditioning (A/C) systems. Since the composition of non-azeotropic refrigerant mixtures changes as refrigerant is lost, either through the vapor phase or the liquid phase, the method of charging A/C systems is important. The purpose of this document is to determine the proper refrigerant phase, liquid or vapor, for system charging by relating system performance changes to the charging method.This document is complete only when combined with the requirements of SAE J1657.
