System Air Leakage Test Standard

SMACNA has included a procedure for leakage testing of ductwork Since January of 1965. This process like many others has evolved after more research and feedback from the industry led to changes in both the pass/fail criteria and the application of testing. The next major leap forward is this standard. It goes beyond the duct and include 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. It does so in a responsible manner where 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 on decades of experience.

OSHA & Regulatory Compliance

OSHA Rule on Silica in Construction

The OSHA rule for silica in construction became effective September 23, 2017 although OSHA included a 30-day “grace period” for full enforcement. SMACNA members affected by this rule are encouraged to take a “holistic” approach to silica compliance by assessing the tasks and processes where silica (found in concrete) is disturbed (cut, drilled, grinded, etc.). SMACNA members should be aware that “Table One” and dust collection tools are not the only options for compliance.
