ANSI/ASHRAE 15-2004 is the newest version of one of ASHRAE''s oldest standards. This version is a republication of ANSI/ASHRAE 15-2001, including addendum a. The reader is referred to that addendum as well as Appendix J of this standard for changes that have been made since the original publication of ANSI/ASHRAE 15-2001. Among those changes were changes to the treatment of flammable refrigerants, including correction of an omission in the 2001 standard. In addition, changes were made to the requirements for pressure vessel protection and references were updated.

This standard is directed toward the safety of persons and property on or near the premises where refrigeration facilities are located. It includes specifications for fabrication of tight systems but does not address the effects of refrigerant emissions on the environment. For information on the environmental effects of refrigerant emissions, see ASHRAE Guideline 3-1996, Reducing Emission of Halogenated Refrigerants in Refrigeration and Air-Conditioning Equipment and Systems.
