A fume hood performance audit is a series of tests conducted to determine the containment characteristics of fume hoods, measuring the capability to contain vapors in “as used” conditions.


Once we have verified that the fume hood and the controls systems are in proper working condition, Belnor will proceed with the following ANSI/ASHRAE 110-1995 fume hood test operation procedures:

  1. 6.1.1 – Flow Visualization* 

  2. 6.2 – Face Velocity Measurements** 

*Smoke pencil testing

**using Shortridge Instruments Inc. Airdata Multimeter


Belnor will provide a complete report detailing the procedures used for testing, condition of each fume hood, recommendations as well as results of the local flow visualization and face velocity measurements.
