Organization: SAE
Publication Date: 1 September 2020
Status: active
Page Count: 10
scope:

This SAE Standard applies to refrigerant identification equipment to be used for identifying refrigerant HFC-134a (R-134a) and HFO-1234yf (R-1234yf) 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 of other refrigerants is the option of the equipment manufacturer, although it shall not misidentify refrigerants, per 3.2.

Purpose

Establishing such specifications will ensure equipment that meets this standard can identify relatively pure refrigerant HFC-134a (R-134a) and HFO-1234yf (R-1234yf) from mixtures of refrigerants (HFC, HCFC, CFC, hydrocarbons, etc.) in a refrigerant supply tank, or mobile system prior to recovering/recycling (R/R) the refrigerant, or prior to charging an A/C system from a refrigerant container. The identifier also shall identify and display weight of non-condensable gases, such as air. The displays shall be in percentages, per 3.1.3, and to the specified accuracies.
