How is purification workshop graded?

Purification workshop, also known as clean workshop, can be divided into the following six levels: 1 00000 clean workshop,110000 clean workshop, 100 clean workshop and first-class clean vehicle.

Extended data:

1000000 class100000 class clean workshop is used in many industrial sectors, such as manufacturing optical products, manufacturing large electronic systems with smaller components, manufacturing hydraulic or pneumatic systems, producing food and beverages, and medical and pharmaceutical industries often use this class clean workshop.

10000 clean room is used to assemble hydraulic equipment or pneumatic equipment, and in some cases it is also used in food and beverage industry. In addition, ten thousand clean rooms are also commonly used in the medical industry.

1000 clean workshop is mainly used to produce high-quality optical products, as well as to test and assemble aircraft snake snail rice and assemble high-quality miniature bearings.

100 class Many people think that this class clean room is the most commonly used clean room, so it is also the most important clean room. People often mistakenly refer to 100 clean room as sterile room to explain the "aseptic" or "clean" environmental requirements.

100 clean room can be used in aseptic manufacturing process of pharmaceutical industry. This kind of clean room is widely used in manufacturing implants, surgery (including transplantation), manufacturing integrators and isolation treatment of patients who are particularly sensitive to bacterial infection, such as isolation treatment after bone marrow transplantation.

10 clean workshop is mainly used in semiconductor industry with bandwidth less than 2 microns.

1 class clean workshop is mainly used for manufacturing integrated circuits in microelectronics industry, and the accuracy of integrated circuits requires sub-micron level.
