A clean room is a space where environmental pollutants are controlled to a specific level. These rooms are commonly utilized in manufacturing, scientific research, and medical applications when even the tiniest of contaminates will compromise a project. Contaminants include things like dust, airborne microbes, aerosol particles and chemical vapors. They can come from facilities, people, tools, fluids, and products. Even cosmetics, including cologne, hairspray, and fingernail polish, are banned from a clean room. While it is impossible to completely eliminate all contaminants, the levels of acceptable contaminates vary by clean room.
Definition of Classes
The controlled level of contamination is designated by the number of allowed particles per cubic meter at a specified particle size. A discrete-particle-counting, light-scattering instrument measures the particles in the air. There are different standards used to denote the accepted level of contaminates. The Federal Standard 209 E … Read More »
