Cleanroom Classification and Applications
Currently, the most commonly used cleanroom classification system is the US Federal Standard FS 209E. A Class 100 cleanroom, commonly referred to as a cleanroom, requires no more than 100 particles of 0.5 microns or larger per cubic foot of space. A Class 10 cleanroom requires no more than 10 particles of 0.5 microns per cubic foot of space, while a Class 10 cleanroom requires no more than 10 particles of 0.5 microns per cubic foot of space, and a Class 1000 cleanroom requires no more than 1,000 particles.
Generally speaking, Class 1 cleanrooms are primarily used in the microelectronics industry, which manufactures large-scale integrated circuits; Class 10 cleanrooms are primarily used in the semiconductor industry, where bandwidths are less than 2 microns; Class 100 is the most commonly used cleanroom, used for sterile manufacturing processes in medicine, surgical procedures, artificial organs, and integrated circuit production; Class 1000 is primarily used in the production of optical products and high-quality miniature bearings, as well as for testing aircraft gyroscopes; Class 10,000 is used in the production of hydraulic and pneumatic equipment, and in some cases, in the production of food and beverages; and Class 100,000 is used in many industrial sectors and is also commonly used in the food and beverage and pharmaceutical industries.
