https://www.yizhongalu.com/resources/types-of-cleanrooms.html A cleanroom is a specially designed and configured room that has been constructed to eliminate dust particulates and atmospheric contaminants. They are commonly used for scientific research, pharmaceutical production, and other industries that produce products that can be damaged by unsanitary or polluted conditions. The classification of a cleanroom is determined by the amount of particulate matter (PM), a descriptor for particles and liquids in the air, it has per cubic meter. The air we breathe has about 35 million particles in a cubic meter with an estimated size of 0.5 μm, micrometers or one millionth of a meter. Cleanrooms are classified by the International Organization of Standards (ISO) that uses a grading system of ISO 1, for extremely clean, to ISO 9, satisfactorily clean. The determination of the classification is decided by the size and numbers of particles in the room's air. The United States classification system for cleanrooms was Federal Standard 209E published by the Institute of Environmental Sciences and Technology (IEST) in 1963. The IEST used a classification system that ran from Class 1, an ISO 3 class, to Class 100,000, an ISO 8 classification. Though several countries still use the IEST system, it was formally retired in 2001 as being obsolete. For many years, scientists, engineers, and designers had attempted to create an uncontaminated atmosphere but failed due to problems with uncontrollable particles and airflow. In 1960, Physicist Willis Whitfield developed a filtration system that led to the development of the modern cleanroom. Requirements for a Cleanroom Cleanrooms are used by specialized industries, such as pharmaceutical, biotech, semiconductors, laboratories, microchip producers, and photovoltaic. Any manufacturing process requiring strictly controlled production and product handling will have some form of cleanroom. The nature and delicacy of a product....
