dc.descriptionThis document is a fact sheet that updates readers on refrigerant standards from the American Society of Heating, Refrigerating and Air-Conditioning Engineers and introduces refrigerants recently assigned “R” numbers and placed on the international market. It explains how Standard 34 assigns refrigerant numbers for pure substances and blends and describes safety classifications that combine toxicity classes with flammability classes, including the newer subclass for slowly burning, mildly flammable refrigerants. It also summarizes safety issues addressed in Standard 15 for refrigeration systems. The document provides a table of refrigerant designations introduced after 2010 with safety groups, global warming potential values, and boiling-point information, and notes cooperation with the United Nations Environment Programme.en
