The cleanliness classification range of cleanrooms typically spans
from Class 1 to Class 100,000 (hundred thousand), with smaller
numbers indicating higher cleanliness levels.
Level 1: Used in the microelectronics industry for manufacturing
integrated circuits, with extremely high requirements.
Grade 10: Primarily used in the semiconductor industry for
applications with bandwidth less than 2 micrometers.
Class 100 (Hundred Level): The number of dust particles with a
diameter of 0.5 micrometers or larger per cubic meter does not
exceed 3,500. It is commonly used in sterile manufacturing
processes in the pharmaceutical industry.
Class 1000 (Thousand-class): The number of dust particles smaller
than 0.5 micrometers per cubic meter is controlled below 3,500,
used for the production of high-quality optical products.
Class 10,000 (10,000-level): The number of dust particles greater
than or equal to 0.5 microns per cubic meter is controlled within
35,000 particles, suitable for the assembly of hydraulic or
pneumatic equipment.
Class 100,000 (100,000-class): Used in many industrial sectors,
such as optical product manufacturing and food and beverage
production.
Class 100 (ISO Class 5): Integrated circuit manufacturing, vaccine
production, high-end optical components, and implantable medical
devices.
Class 1000 (ISO Class 6): Medical device assembly, pharmaceutical
production, and high-quality optical product testing.
Class 10,000 (ISO Class 7): Food and beverage processing, cosmetics
production, conventional pharmaceutical manufacturing, and plant
tissue culture.
Class 100,000 (ISO Class 8): Automotive components, machining,
electronic component assembly, food packaging.
Class 300,000 (ISO Class 9): Suitable for scenarios with less
stringent cleanliness requirements, such as agricultural
cultivation, textile manufacturing, and warehousing.
