The American National Standards Institute (ANSI) announced that SMACNA’s “HVAC Duct Construction Standards – Metal and Flexible,” third edition, was 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 new ANSI status will also enhance SMACNA’s overall credibility as a standards developing organization, both domestically and internationally.

The 390-page “HVAC Duct Construction Standards – Metal & Flexible” manual is intended primarily for commercial and institutional duct construction. The standard contains tables and details for constructing ductwork for ½ inch to 10 inch wg positive and negative pressures. This edition improves upon the second edition with expanded pressure class tables, separate tables for TDC/TDF construction and expanded tables for round duct construction including 6 inch wg positive and negative pressure and sizes up to 96 inches. 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.

Members may purchase the 390-page “HVAC Duct Construction Standards - Metal & Flexible,” (third edition, 2005), at the special member price of $35 for the book, $41 for the CD-ROM, $52 for the CD/book combination and $35 for the PDF download.

Architects and engineers may purchase the new publication at the discounted price of $151 for the book, $178 for the CD-ROM, $204 for the CD/book combo and $151 for the PDF download. The list price for the book is $215, the CD-ROM is $255, the CD/book combo is $339 and the PDF download is $215.

ANSI does not develop American National Standards. It facilitates standard development by assuring that consensus is established among qualified and affected interest groups. The Institute ensures that the guiding principles of consensus, due process and openness are adhered to by organizations developing standards under its review to provide a coherent U.S. standards strategy.
