  • Fibrous particle generating apparatus and test system
    Patent number: 8176802
    Abstract: There is provided a fibrous particle generating apparatus and a test system. The fibrous particle generating apparatus includes a base material containing a fibrous material; a holding unit holding the base material; a fibrous particle generator generating fibrous particles by chafing the base material; and a movement unit moving the holding unit such that the base material held by holding unit is chafed against the fibrous particle generator. With this configuration, fibrous particles can be stably generated, and an evaluation of the object apparatus can be carried out on the basis of the generated fibrous particles.
