ANSI/ASHRAE 110 - 1995:

Method of Testing Performance of Laboratory Fume Hoods


The ANSI Z9.5 Laboratory Ventilation Standard States:

"The tracer gas containment tests shall be conducted in the ANSI/ASHRAE 110-1995 Method of Testing Performance of Laboratory Fume Hoods or by a test recognized to be equivalent" (Source: ANSI/AIHA Z9.5-2003 (Sec. 6.3.7))

All new fume hoods shall be evaluated on-site to achieve an acceptable ASHRAE 110 - 1995 "AI" (As Installed) rating. This is critical for successful containment control. We will work with your team to develop acceptable "AI" ratings for each hood, provide the evaluation and, if necessary, a clear plan for corrective action.

The Commissioning Report includes all ASHRAE 110 Target Test Data vs. Measured Performance. Concerns, if any, are identified during the evaluation and recommended corrective action outlined.
 
This approach ensures chemical fume hoods and laboratory design work in harmony. The “AI” rating evaluation serves several purposes:
  • It recognizes that laboratory design factors have a significant impact on chemical fume hood performance
  • It recognizes that simple changes can positively impact performance
  • It provides a quantifiable benchmark measurement for each hood
  • It educates the end user of the operational limits of each hood
  • It establishes the required recording keeping system for your facility
  • It educates the end user about fume hood safety and use
We look forward to working with you. Together we will define the desired end result and long-term approach to Laboratory Ventilation Management that is a good fit for your facility and budget.
