SMACNA 016-2012

HVAC Air Duct Leakage Test Manual

This American National Standard, ANSI/SMACNA 016-2012, covers revised leakage criteria and builds on the proven methods for testing ductwork for air leaks from the first edition. Contains updates to the expected leakage rates for ductwork constructed to the SMACNA HVAC Duct Construction StandardsùMetal & Flexible, duct leakage test procedures, recommendations on use of leakage testing, types of test apparatus and test setup and sample leakage analysis. Includes a new educational chapter for designers and specifiers, to aid in the specification and implementation of duct leakage and testing methods.


SMACNA 1108-2008

Accepted Industry Practice For Industrial Duct Construction

This guide is a compilation of accepted industry practices and construction reinforced or unreinforced, for operation from 4 in. to 20 in. wg positive or negative pressure, and from ambient to 650 F for carbon or stainless steel, 400 F for galvanized steel, and 120 F for aluminum. Also rectangular duct fabricated from panels from a few inches up to 5 ft wide, all welded, Pittsburgh, grooved seam pipe lock or standing seam joined duct, for operation from 4 in. to 20 in. wg positive or negative pressure, and for the same materials and temperature limits as round duct. Also includes chapters on industrial applications, material properties, hangers and supports, fittings, vents, doors, discharge ducts (small stacks) and surface preparation of metals.


SMACNA 1167-2011

Guide For Free Standing Steel Stack Construction

Contractors, designers, and engineers will find this guide a very valuable resource, as tables containing hundreds of stacks are detailed and ready to go. This new publication updates the 1996 Guide for Steel Stack Construction, second edition, incorporating text and tables. New are design considerations for free standing stacks under resonant vibration, established limits on stacks fitted with testing platforms, larger stack selection diameters, and consideration of custom designed anchoring systems instead of a standardized schedule. Includes tables for selection of free standing stacks from 20 feet to 120 feet high, and diameters to 120 inches, companion flange, stiffener sizes and stacks with access ladders and platforms.


SMACNA 1520-1999

Round Industrial Duct Construction Standards

This edition expands the scope of the 1977 version, updating original text to incorporate a revised theory of design, new materials and more ôuser friendlyö tables. Offers a standardized, engineered basis for design and construction of industrial ducts of Classes 1 to 5. Includes a spiral duct chapter for Classes 1 and 2, covers design pressures ranging from 30ö wg negative to 50ö wg positive, plus carbon and galvanized steel tables. Changes to the manual include expanded tables for stainless steel and aluminum, 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 table use, the publication has a manual calculation procedure using equations and fully developed examples, and offers optional calculation software. Includes soft metrics.


SMACNA 1922-2004

Rectangular Industrial Duct Construction Standards (Inch Pound)

The second edition of the Rectangular Industrial Duct Construction Standards expands the scope of the 1980 version, updating original text to incorporate a revised theory of design, new materials and more ôuser friendlyö tables. Included are new tables for stainless steels and aluminum, plus expanded chapters on materials, welding practices, and a guide specification. It covers the simple, low or moderate temperature and pressure (or vacuum) indoor systems as well as the more complex outdoor systems that operate at moderate to high temperature and pressure (or vacuum), and are subject to higher and more complex external loading.


SMACNA 1966-2005

HVAC Duct Construction Standards - Metal & Flexible

The third edition of the HVAC Duct Construction Standards û Metal and Flexible is intended primarily for commercial and institutional duct construction. The standard contains tables and details for constructing ductwork for ╜ö to 10ö 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 6ö wg positive and negative pressure and sizes up to 96ö. 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. Includes soft metrics.


SMACNA 1987-2006

HVAC Duct Systems Inspection Guide

Contains guidelines for inspection of commercial HVAC duct systems for compliance with SMACNA/ANSI HVAC Duct Construction StandardsùMetal and Flexible, (3rd Ed.) and Fibrous Glass Duct Construction Standards (7th Ed.). It reviews materials and reinforcement of duct systems, as well as assembly and supports of ducts. The Fire, Smoke and Radiation Damper Guide (5th Ed.) also summarizes installation details. Checklists are included for ductwork and fire dampers. Valuable as a study guide for the HVAC Duct Construction Standards manual and for learning inspection procedures in general. Includes soft metrics. -
