The 2013 editions of ASHRAE’s major refrigerants-related standards, incorporating 41 new addenda, have been published. Requirements in ANSI/ASHRAE Standard 34-2013, Designation and Safety Classification of Refrigerants, and ANSI/ASHRAE Standard 15-2013, Safety Standard for Refrigeration Systems, complement each other in that Standard 34 describes a shorthand way of naming refrigerants and assigns safety classifications based on toxicity and flammability data.
