Classification of Cleanroom based on Functionality

Typically used in manufacturing or scientific research, a cleanroom is a controlled environment that has a low level of pollutants such as dust, airborne microbes, aerosol particles, and chemical vapors. To be exact, a cleanroom has a controlled level of contamination that is specified by the number of particles per cubic meter at a specified particle size. The ambient air outside in a typical city environment contains 35,000,000 particles per cubic meter, 0.5 mm and larger in diameter, corresponding to an ISO 9 cleanroom which is at the lowest level of cleanroom standards.

A room in which the concentration of airborne particles is controlled, and which is constructed and used in a manner to minimize the introduction, generation, and retention of particles inside the room and in which other relevant parameters, e.g. temperature, humidity and pressure are controlled as necessary.

Cleanroom is defined as “a specially constructed room in which the air supply, air distribution, dust and airborne particle, room pressure, temperature and humidity are environmentally regulated to meet appropriate cleanliness level”.

In the high technological industries such as electronics, optical and biological industries, the newly developed commodities are manufactured with precise fabrication as a basic process.
