4001 -- Development of Ventilation Rates and Design Information for Laboratory Animal Facilities. Part 2 - Laboratory Tests PDF

Reports on the study of eight ventilation parameters (room air exchange rate, diffuser neck diameter, diffuser type, number of returns, return location, cage type, room size and cage rack arrangement) for laboratory animal facilities in a full-scale room ventilation simulator. Air exchange rates, velocities and temperatures within the room and the cages were studied. Finds that cage type was the most important factor affecting cage conditions. The remaining factors did not significantly affect cage conditions in the ranges studied. Summarises the results in tables.
