Using published procedures, 10 commercially available cleanroom wiping materials were tested and evaluated for characteristics related both to functionality and to contamination. The sorptive capacities of these 10 wipers were found to span a range from 100 to 500 mL/m2, while rates of sorption cover two orders of magnitude, from 30 to 3000 mL/m2/s. Particles are reported as readily releasable particles, those easily removed from wipers using water, and as particles which are generated in response to the administration of frictional energy. Data are also given for extractible matter with two solvents, water and 2-propanol, and for the total mass of inorganic matter as measured by the level of high-temperature ash. The data related to contamination cover several orders of magnitude and are reported not only per unit area and per unit mass, but also on a unique basis introduced here: unit of filth per unit of function.
