ASHRAE publishes 2016 refrigerant standards

USA: The 2016 editions of ASHRAE’s major refrigerants-related standards have been published as a package with 30 new refrigerants and refrigerant blends added.

ANSI/ASHRAE 15, Safety Standard for Refrigeration Systems, and its sister standard, ANSI/ASHRAE 34, Designation and Safety Classification of Refrigerants, constitute a complete set of requirements for the safe design, construction and application of refrigeration systems used in a wide variety of residential, commercial and industrial applications.

For both of the standards, the updates come from a continuing stream of changes made based on new science and research, experience, and proposals from designers, manufacturers and users.

The 2016 edition of Standard 15 incorporates addenda a, b, c, e and g to Standard 15-2013.  These include changes to the safe design, construction, installation and operation of refrigeration systems; updated requirements for safety relief systems, including revisions to relief vent pipe discharge locations and design provisions for headered relief vent systems; updated design pressure requirements for CO2 systems; modified overpressure protection for heat exchangers and pressure limiting devices for positive displacement compressors.

The 2016 edition of Standard 34 incorporates 35 addenda to the 2013 edition. These include the addition of three new refrigerants and 27 new refrigerant blends and changes to the requirement for submission of standard test result data to validate the method used to determine burning velocity.

The cost of ASHRAE Standards 15 and 34, which are packaged together, is $95 for ASHRAE members ($112, non-members). To order, visit www.ashrae.org/bookstore.
