1. Definition of ISO 14644-1 Cleanroom
According to the explanation of "Code for Design of Clean Workshop" (GB 50073-2001), an ISO cleanroom is a room with controlled concentration of suspended particles in the air. It should be constructed and used to reduce indoor attraction, generation and retention of particles. Other indoor parameters such as temperature, humidity, pressure, etc. are controlled as required.
It can be seen that an ISO cleanroom is a special room, and parameters such as air suspended particle concentration, air temperature, humidity, and pressure in the room need to be controlled. And it should have the effect of reducing the attraction, generation and retention of particles. This needs to be achieved through the joint action of good airflow organization, effective pressure difference control, ISO cleanroom shape and decoration materials that meet process requirements, skilled construction technology, and scientific operation management. The size of the ISO cleanroom ranges from a few square meters to several thousand square meters. The ISO cleanroom of several thousand square meters is composed of small cleanrooms arranged scientifically according to the conditions of production technology, production process and pollution control theory. The so-called clean workshop.

3.ISO 14644-1 Cleanroom Industry Applications
Cleanrooms can be classified into two categories: industrial cleanrooms and biological cleanrooms.
(1) Industrial cleanroom It mainly controls the pollution of inanimate particles to the operating objects. The main application fields are aerospace industry, precision machining industry, integrated circuit production enterprises, film production enterprises, atomic energy industry, printing enterprises, etc.
Biological cleanroom It mainly controls the contamination of living particles to the operating objects. Its application fields include pharmaceutical companies, food processing industries, disease control centers, medical units, laboratory animal rooms, scientific research and teaching experiments, etc. For biosafety laboratories, in addition to controlling the contamination of living particles to the operating objects, it is also required to control the contamination of potentially harmful operating objects to the operators and the surrounding environment. Therefore, the control of differential pressure is more important in biosafety laboratories.
