ANSI Approves SMACNAs New HVAC Duct Construction Manual

The American National Standards Institute (ANSI) announced that the Sheet Metal and Air Conditioning Contractors’ National Association’s (SMACNA) new HVAC Duct Construction Standards, Metal and Flexible, third edition, has been approved as an American National Standard, designated ANSI/SMACNA 006-2006.
ANSI recognition increases the potential that SMACNA’s standards are internationally adopted for industry and regulatory use. The approval will also encourage wider domestic use of SMACNA’s standard by state- and local-code governing bodies as well as the design and engineering community.
The 390-page manual is intended primarily for commercial and institutional duct construction. This updated edition features expanded pressure class tables, separate tables for TDC/TDF construction, and expanded tables for round duct construction including 6-in. wg positive and negative pressure, and sizes up to 96-in.
New in this edition is an engineering and design chapter to provide additional information to design professionals, double-wall construction details, new casing construction details, and additional accessory items. The standard is applicable for construction using uncoated steel, galvanized and stainless steels, and a limited range of aluminum ducts. This standard has been adopted in the ICC International Mechanical Code.
To order, call SMACNA’s Publications Department at 703/803-2989 or visit www.smacna.org/bookstore.
