Improved Control Of Cleanroom Materials Characterization

Various materials are present in controlled environments, such as pharmaceutical or food and beverage manufacturing areas. These materials may be part of the manufacturing process, as is the case with a polystyrene bag for example, or may be used in critical environments, such as with gloves and wipes. Use of these materials can result in significant particle generation. Therefore, characterization of such materials is valuable in understanding a controlled environment and the particles therein.

Materials can vary widely in their particle shedding tendencies. Manufacturers may report material particulate levels, often in units of particles per square meter, which can be useful in selecting low particulate shedding cleanroom wipes and gowns. Such information is not provided for all materials; however, and when provided, may not supply an adequate measure of the likelihood or risk of the material to introduce particles into a controlled environment.
