4. 1 .3. 1 .4 Room With Racks, Cages and Simulated Animals: Test Procedure 
The test room was divided into seven zones for data collection, as indicated in figure 4.50. The 
total number of measurement locations is shown in table 4.1.14. The room mean air velocity, 
median air velocity, range of air velocity, temperature, TI, and CO 2 concentration patterns were 
determined at 0.30m (12”) increments throughout the room. Measurements started 0.05m (2”) 
from racks and walls. Temperature measurements were obtained with type -T thermocouples, air 
velocity with the BERL air velocity sensors, and CO 2 with the Fuji gas monitor (Fuji Electric 
Co., model ZEP5YA31). This equipment and their calibration procedures were described section 
4.3. 1.2. All sensors were calibrated prior to the start of this experimental sequence except for the 
thermocouples. The sensors were moved around the room with a traverse system as described 
earlier so no people entered the room during or 10 minutes prior to any measurements. A view of 
the measurement sensors on the traverse system is shown in figure 4.51.
