One purpose of ANSI/ASHRAE Standard 34, Designation and Safety Classification of Refrigerants, has been to provide safety classifications for refrigerants that reflect their flammability potential.
This paper provides a description and brief history of refrigerant flammability safety classification systems, a summary of a literature survey of flammability test data for single-compound refrigerants and refrigerant blends, and also presents new flammability test results on the lower flammability limits (LFLs) of refrigerants and refrigerant blends containingflammable components that are currently ASHRAE designated and classified. The results presented were determined under ASHRAE Research Project 1073. The new LFL data are relative to new test method requirements set forth in proposed Addendum p to ANSI/ASHRAE Standard 34-1992 (34P-1992). With the results presented here, a self-consistent database of flammability results now exists to support ASHRAE flammability safety classifications under 34p-92.
