Abstract: A method for abrasion testing of a material sample includes abrading a surface of the sample with a tribometer, then characterizing particles in a portion of the flowing air that is received in an airborne particle collector. The testing may be done in an enclosure or container, such as an enclosure in or simulating a clean room environment. The drawing of air into the enclosure may be done by a fan pushing in air through a filter, such as a high efficiency particulate air (HEPA) filter. The enclosure may have vents (or louvers) through which some of the outflow of air may be directed, to help maintain an even flow, for example a laminar flow, of air through the container, and in particular past where the tribometer abrades the test material. The method may allow for real-time characterization of the particles produced by the testing.
