8th Edition Includes Expanded and Revised Content

The Associated Air Balance Council (AABC) announces the publication of the AABC National Standards for Total System Balance, 8th Edition. This comprehensive manual for the test and balance industry, last updated in 2016, details the minimum standards for total system balance, assists design professionals in achieving design intent, provides a better understanding of the scope of work required of the TAB agency, and ensures that proper methods and procedures are followed in the test and balance process.
Like the 7th edition, this newest version is American National Standards Institute (ANSI) approved. ANSI approval signifies that the procedures used by AABC in connection with the development of the standards meet the Institute’s essential requirements for openness, balance, consensus and due process.
“It’s important to keep updating the standards because the industry is changing,” said AABC Standards Committee Chairman Gaylon Richardson (Engineered Air Balance Co., Inc.). “Updating the systems and procedures is essential to AABC’s identity as the leader in our industry. Anyone involved with HVAC systems needs a copy… everybody needs to know this information.”
