Abstract
In at least one implementation, a blank washer inspection process includes the steps of: applying at least one test particle to a blank; washing the blank having the test particle thereon; inspecting the blank after it has been washed to identify any test particle on the blank; and comparing any test particle identified in the inspection step to a threshold. The threshold may relate to a control property of the test particle. In at least some implementations, the control property is the size of the particle and a maximum size may be set as a threshold. Other control properties may be used. Further the test particles may include detection properties to facilitate identifying test particles and distinguishing among test particles in different groups.
