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. Standard 15 establishes rules for safe refrigerant application in equipment and systems. ASHRAE is selling the standards as a set.

Standard 34-2013 contains the 2010 standard and 36 published addenda. Standard 15 contains the 2010 standard plus five published addenda.
