AABC Publishes Updated National Standards for Total System Balance

8th Edition Includes Expanded and Revised Content

8th edition cover update

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.”

New, additional and revised content includes:

  • Updates to TAB report requirements & structure.
  • Updated requirements for instrumentation, calibration, and tolerances.
  • Updated Pitot tube traverse requirements.
  • Added information covering fan laws.
  • New recommendations regarding total leakage for air leakage testing.
  • Updated procedures for testing constant and variable volume systems.
  • New discussion of fan system equations.
  • Added information on energy recovery and temperature control systems.
  • New discussion of AFLDs and PICVs.
  • Updated information about cooling tower testing.
  • New boiler plant procedures.
  • Significant updates to laboratory and kitchen systems.
  • Updates to smoke control testing.
  • A rewritten chapter on HVAC commissioning and commissioning plan.
  • An entirely new chapter with expanded information on underfloor air distribution systems.
