Mar 1, 2002 12:00 PM
The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) has published ANSI/ASHRAE Standard 34-2001, Designation and Safety Classification of Refrigerants. This standard establishes a simple means of referring to common refrigerants. It also establishes safety classifications.
Standard 34-2001 incorporates the 1997 standard as well as 17 previously approved addenda. The standard is published on a three-year cycle. Five new addenda have been incorporated: 34m, 34n, 34r, 34s, and 34t. These add designations and safety classifications for R414B, R416A, and R417A; change the safety classification of R245fa to B1; and change the composition tolerances for R402A and R402B.
The cost of Standard 34-2001, Designation and Safety Classification of Refrigerants, is $45 ($36 for ASHRAE members). To order, phone 800-527-4723 (United States and Canada) or 404-636-8400 (worldwide), fax 404-321-5478, visit the ASHRAE Online Bookstore at www.ashrae.org, or contact 1791 Tullie Circle NE, Atlanta GA 30329.
