This SAE Recommended Practice applies to refrigerant blends (multicomponent refrigerants) intended for use as retrofit refrigerants to replace CFC-12 (R12) in mobile air conditioning 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 air conditioning 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.
The SAE Interior Climate Control Standards Committee consists of a Steering Committee plus the following sub-committees: Fluids, MAC Supplier, Service, and Vehicle OEM. The SAE Interior Climate Control Standards Committee has published more than 50 documents and has an HS-2900 handbook. These documents include standards on safety, refrigerants, components, testing, service procedures, service equipment, and training. Many of these standards are cited in EPA regulations. SAE ICCC membership includes engineers from every global automaker, system and component supplier, and service equipment manufacturer many of which are considered to be experts in Automotive Climate Systems.
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.

Search Tips: Search Operators:AND, OR, NOT; Wild Cards; Using Quotes
SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Wild Cards
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
