Full Description

First published in 2000, Standard 126 is a joint project of ASHRAE and SMACNA, the Sheet Metal and Air Conditioning Contractors National Association. It was created to provide methods of testing to determine the strength and durability characteristics of HVAC duct and fittings under various loading and environmental conditions. To the project committees knowledge, no other publication covers all of the structural and durability tests as comprehensively as this standard, although individual tests are covered under other standards. The intent of this standard is to cover all duct shapes and materials.
