IHSC conducts laboratory hood testing utilizing the ASHRAE 110-1995 Method of Testing Performance of Laboratory Hoods.
This includes the following tests:
- Flow visualization using small and large amounts of smoke;
- Face velocity measurements from the face of the fume hood; and
- Tracer gas containment using a mannequin.
IHSC uses SF6 (sulfur hexafluoride) as the trace gas and Miran Sapphire as the continuous reading gas detector.
