Dear Chip and Colleagues--For fume hood performance issues, use 
ANSI/AIHA Z9.5-1992, "Laboratory Ventilation".  For testing, use 
ANSI/ASHRAE 110-19995, "Method of Testing Performance of Laboratory 
Fume Hoods".  These standards are not available on the Web, but you 
can purchase them from ANSI or perhaps find a copy at your local 
college or university library.   You could also consult with a 
competent PE who is knowledgeable concerning lab HVAC design issues 
(hard to find in some markets!).  Good luck with your projects.  Tom
