The American National Standards Institute (ANSI) announced that SMACNA’s “Round Industrial Duct Construction Standards,” second edition, has been approved as an American National Standard.

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 642-page “Round Industrial Duct Construction Standards” offers a standardized, engineered basis for design and construction of industrial ducts of Classes 1 to 5. It includes a spiral duct chapter for Classes 1 and 2 and covers design pressures ranging from 30-inch water gauge negative to 50-inch water gauge positive, plus carbon and galvanized steel tables. Also included are expanded tables for stainless steel and aluminum, plus expanded tables for duct sizes up to 96 inches in diameter, introduction of a new Duct Class 5 for systems handling corrosives, and spiral lockseam pipe. As alternatives to using tables, the publication has a manual calculation procedure using equations and fully developed examples, and offers optional calculation software.

SMACNA members may purchase the “Round Industrial Duct Construction Standards,” 2nd edition, at the member price of $64 for the book, $77 for the CD-ROM and $64 for the PDF download. The IFUS price for the book is $137, $164 for the CD-ROM and $137 for the PDF download.

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.
