ashrae 110 testing
ASHRAE 110 is an American National Standard for the method of testing performance of laboratory fume hoods. As a part of this performance testing the tests required are: face velocity measurement and smoke containment visualization as a means of documenting a fume hood's performance and for comparison to current standards (ANSI/AIHA, SEFA). This testing and certification procedure is a part of a lab's chemical safety management program. Other aspects, including preventative maintenance and inspections, chemical exposure monitoring, and periodic ASHRAE 110 (utilizing a tracer gas) testing can give a facility a complete program for fume hood management.
