ABSTRACT:
A method and apparatus for testing a gas mask filter element comprising, ple supply means for supplying a test sample, a filter element box for containing a gas mask filter element, said element box having a sample inlet connected to said sample means for supplying a test sample to a filter element in the element box to form an effluent in the box, and an effluent outlet for discharging the effluent from the box. An inhalation chamber defining a space and having an effluent inlet connected to said effluent outlet for supplying effluent into said space, said inhalation chamber having a chamber outlet for discharging effluent from said space. At least one plethysmographic box connected to said inhalation chamber for receiving a test animal and having an opening communicating with said space through which the head of a test animal can pass into said inhalation chamber space. Respiration response means connected to said plethysmographic box for measuring a respiratory response of a test animal therein, and a breathing pump connected to said chamber outlet for drawing effluent from said inhalation chamber space in a manner which simulates human respiration.
