- GENERATION OF TEST ATMOSPHERE / CHAMBER DESCRIPTION
- Exposure chamber volume: 435 liter stainless steel chamber
- Method of holding animals in test chamber: the animal room, reserved exclusively for rodents on acute tests, was maintained at 20 - 21°C and was kept clean
- System of generating vapours: Harvard pum
- Temperature: 20 - 21°C
- Total Volume of Air: 2175 liter/minute
TEST ATMOSPHERE
- Brief description of analytical method used: the test material was introduced into a distilling flask at a constant rate by use of a Harvard pump. The vapors generated were introduced into the air stream. The dosage amount was calculated from the air flow and the amount of liquid material used.
