SMACNA Launches System Air Leakage Testing Standard

Oct 15, 2020

SYSTEM AIR LEAKAGE 250x308SMACNA has officially launched the First Edition, System Air Leakage Testing Standard. This must-own publication will be an immediately welcome addition to SMACNA members’ resource libraries.

SMACNA Member firms and Chapters are each entitled to one free* copy of this new Standard. An email went out earlier to chapter executives and member primary contacts (owners, presidents, CEOs) with a promo code that can be used to order either one PDF download or one hard copy book. Please refer to that email for information on how to get your free* copy of this Standard.

Since 1965, SMACNA has included a procedure for leakage testing of ductwork (HVAC Duct Construction Standard & HVAC Air Duct Leakage Manual). This process, like many others developed by SMACNA, has evolved over time based on research and feedback from the industry, resulting in changes to both the pass/fail criteria and the application of testing.

The culmination of that feedback and research is this standard. SMACNA’s System Air Leakage Test Standard goes beyond the duct and includes procedures for any item included in a forced air system. This standard addresses leakage testing of any portion of, and up to, the entire forced air system.

The pass/fail criterions are based on sound research specific to testing conditions, and distributes the responsibility of system performance equitably. The testing process is reliable, practical, and based is on decades of experience. 

*Each SMACNA chapter and member firm is entitled to one free copy of the System Air Leakage Testing Standard. This free copy is limited to either one PDF download or one hard copy book. Hard copy book orders will be subject to a shipping fee.
