A particle counter testing method includes the steps for storing particles in a container, blowing a compressed gas through an inlet flow path, through a wall of the container, into the particles that are stored within the container, spraying the particles that are blown by the compressed gas to outside of the container through a nozzle that is provided on the container, and measuring the number of particles by a particle counter. In the method, an outer shape of the nozzle is a conical shape. The compressed gas is blown into the container through an inlet flow path so that a pressure of a sprayed aerosol gas flow that includes particles is lower than a pressure of a surrounding gas. |
