SMACNA Publishes New HVAC Duct Systems Inspection Guide
The Sheet Metal and Air Conditioning Contractors’ National Association has published the fourth edition of its HVAC Duct Systems Inspection Guide, which is available digitally and in print.
The manual contains guidelines for inspection of commercial HVAC duct systems for compliance with SMACNA/ANSI HVAC Duct Construction Standards, Metal and Flexible, (4th edition), Fibrous Glass Duct Construction Standard (8th edition) and Phenolic Duct Construction Standards (1st edition). It reviews materials and reinforcement of duct systems, as well as assembly and supports of ducts. The Fire, Smoke and Radiation Damper Guide (6th edition) also summarizes the installation, maintenance and inspection of fire life safety dampers. The Grease Duct Construction Reinforcement Standards (1st edition) covers common construction and reinforcements for Type I grease ducts. Checklists are included for ductwork and fire dampers.
The updated 210-page standard was revised to provide the information needed to apply effective and efficient solutions to projects. The manual includes chapters on timing and risks related to inspection, as well as qualifications for inspectors, compliance and quality control, among other topics.
